Knowledge About 3d Printer

1. Early life and career of 3d printer

Jimmy Snyder was born in 1934 in New Brighton, Pennsylvania and soon moved to Wheeling, West Virginia as a young man, working as a coal miner to support his family. His professional music career began at the age of seventeen, when he was invited to play on the local WWVA radio show, "Wheeling Jamboree," in Wheeling, West Virginia.

One of the earliest bands that Snyder played in was Toby Stroud and The Blue Mountain Boys. The boys primarily played bluegrass, boasting the talented fiddle player, Toby Stroud, who would soon have a very successful career as a bluegrass fiddler. Toby Stroud and The Blue Mountain Boys enjoyed minor success with their song entitled "Jesse James.

" Today, the song is recognized as a classic example of early Bluegrass music, oftentimes included on compilation albums. Snyder soon found his way to Los Angeles, California, after his service in the US military. He began playing with the Gene Davis band in the mid-1950s.

By 1959, the Gene Davis Band had a regular gig at The Palomino Club of North Hollywood. Snyder began getting recognition, as the band was soon advertised as "The Gene Davis Band featuring Jimmy Snyder." Snyder left the Gene Davis Band in 1961 and found his own gig at the Rag Doll Club, while Gene Davis attempted to replace him with Johnny Paycheck, but Paycheck soon lost the gig and it was given to Jerry Inman.

Jimmy Snyder was first signed to country label Toppa Records in the early 1960s. Among other early Toppa artists were Gene Davis, Johnny and Jonie Mosby, Wade Ray, Johnny Dabbs, Kenny Brown, and Lina Lynne. He was briefly signed with K-Ark Records in the late 1960s.

In February 1971, K-Ark merged with B.J.B Records of Hollywood and Snyder had releases in the weeks to follow, along with Tony Booth and Bobby Bakersfield.

He signed with Wayside Records, where he enjoyed the most commercial success of his career, produced by Little Richie Johnson. It was under Johnson's production that Snyder scored his biggest hit, "The Chicago Story", a song about a soldier's wife seeing him off to war, with a twist ending that was considered to be controversial at the time of the single's release. By the 1970s he was signed with American Heritage Records.

In 1972, the Shelby Singleton Corportatio signed a contract with American Heritage Records for exclusive distribution rights. While signed to American Heritage, Snyder's "Candy" reached the country charts. Little Richie Johnson once again produced Snyder on American Heritage Snyder made several film appearances, including the cult classic "Rock All Night" and Clint Eastwood's "Any Which Way You Can".

Snyder left California in the 1980s and moved to Nashville, Tennessee, where he played in Printer's Alley, mentoring several aspiring country musicians, including Tim McGraw and Trace Adkins, giving them their first gigs. After playing Printer's Alley, he landed the house gig at Tootsie's World Famous Orchid Lounge, where he plays with the Jimmy Snyder Band.

Black Legion of 3d printer

Effinger took control in 1931 of the Black Legion; he believed it could be the basis for a network of revolutionary cells. He supported expansion by a military structure of brigades, battalions, etc. and soon advocated a revolution, intending for the Legion to seize power in Washington D.

C. and install him as dictator. Effinger described his movement as "a guerrilla army designed to fight the Republican and Democratic parties".

He rewrote history, claiming that the Legion dated to the revolutionary-era Boston Tea Party, rather than the 1920s. Under Effinger's vision, the Legion expanded in Ohio and Michigan during the early 1930s of the Great Depression, where a chapter was first founded by Arthur Lupp in Highland Park in 1931. Its membership was similar to those previously attracted to the KKK: white Protestant native-born men, many from the South, who were threatened by immigration and other changes in society; many lacked skills for the industrial jobs of major cities.

While Effinger claimed leadership, the chapters were highly independent. The Black Legion members had a long list of enemies: immigrants, Catholics, Jews, blacks, labor organizers, communists, and socialists. The Black Legion was linked in Michigan especially to a handful of racist and political murders as well as attempts to appeal to a wider base of the community by arson and bomb attacks on communist bookshops and labor organizers.

The Black Legion expanded even more in Michigan than Ohio, reaching an estimated membership of 20,000 to 30,000 in the mid-1930s, with one third based in Detroit. They were later found to have been particularly influential in Highland Park, Michigan, with a mayor, chief of police, and city councilman as members, among many others. Their network helped members get jobs and exert political influence.

In May 1936 Charles Poole, a Catholic Works Progress Administration organizer, was shot and killed in southwest Detroit, Michigan by Legion member Major Dayton Dean after being kidnapped by him and a gang of followers. While crimes against non-whites or communists were often ignored by small-town police at the time, offenses for religious affiliation tended to be taken more seriously. Poole's killers were vigorously pursued by Detroit city police and the Wayne County Prosecutor's office.

Dean pleaded guilty and testified against other members of his gang and the Legion; he and ten others were sentenced to life in prison. Investigations resulting from his testimony and public outrage about the group led to convictions of another 37 men for crimes ranging from attempted murder to other murders; they all received prison sentences. With so many leaders jailed, the Black Legion collapsed.

Introduction to 3d Printer
Introduction to 3d Printer
1. Protector of Aborigines of 3d printer After arriving in Sydney in November 1838, Sievwright lived briefly with his wife, Christina, and their seven children in Melbourne. The whole family then moved to live among the Aborigines in the Geelong area. This was on the edge of the area assigned to him, known as the Western District, covering about 40,000 square kilometres. British and Irish settlers had begun arriving in the District about three years earlier, but at the time thousands of Aboriginal people still far outnumbered the Europeans. As a Protector of Aborigines, Sievwright was commissioned by the British government to represent the Aboriginal people, and to protect them "from cruelty, oppression and injustice" and "from encroachments upon their property". In February 1841, Sievwright and his family moved further into his district to set up a new camp at Lake Keilambete, near present-day Terang. A year later, he moved to Mt Rouse, near present day Penshurst, again urging the Aborigines of the district to join him. Sievwright's difficulties were considerable, not speaking the languages of the Aborigines under his care, and most of them coming into contact with Europeans for the first time. Nevertheless, at each of his camps he launched limited agricultural training programs in return for food, when traditional food supplies became scarcer as more European settlers arrived with sheep and cattle. At the same time, he launched a series of investigations into the killing of Aboriginal people. His efforts to seek prosecutions of Europeans involved in killings made him extremely unpopular among the white settlers. One squatter recorded in his private journal that by February 1840, Sievwright had already become "the most unpopular man that ever breathed". Around the same time, the Port Phillip Gazette reported that Sievwright was "in very bad odour" with the squatters of the Western District. "These gentlemen, it appears, cut him upon all occasions, and will not suffer him to enter their houses." In August 1842, Sievwright was told that he'd been suspended without pay because of charges against his moral character, dating back to 1839. Port Phillip's Superintendent Charles La Trobe told NSW Governor George Gipps in Sydney that even if the charges against Sievwright were false, they had been "from the outset fatal to him and his recent career". Chief Protector Robinson had already backed a plan to sack Sievwright months earlier. Even before Sievwright learned of his suspension at Mt Rouse, it had been reported in Melbourne by the Port Phillip Gazette. At the same time, the Gazette referred to a threat by the colonial government to refuse squatting licences in part of the Western District where Sievwright had reported the recent murders of three Aboriginal women and a child. "There is still some doubt if the whole affair has not been exaggerated," it said. After it became apparent that Sievwright's suspension was based at least in part on a letter written by his own wife in 1839, both she and their eldest daughter, Frances, wrote to La Trobe defending him.However, Sievwright remained suspended, and the family slipped into poverty. "Mr Sievwright's situation precluded him from making friends among the white population," a man called Frederic Nesbitt wrote to La Trobe. "Therefore they are now suffering the penalty of having done their duty to the Aborigines." Geelong Police Magistrate Nicholas Fenwick confirmed the family's plight, telling the Superintendent: "Nobody here it appears will give them anything on credit now that Mr Sievwright has been suspended, and how they manage to get their daily bread, nobody can tell, and their children are in rags." In London, Secretary of State for War and the Colonies, Edward Smith-Stanley, endorsed Gipps' recommendation that Sievwright be dismissed. "I should wish if possible to avoid pursuing this matter further, as it is not of a character fit for public investigation," he told the Governor. La Trobe and Gipps continued to reject Sievwright's demands for a full inquiry into the allegations that had led to his dismissal. They agreed only to two inquiries into subsequent claims raised in 1844 that he'd misappropriated government stores. Sievwright told La Trobe he regretted to state that Chief Protector Robinson was his "openly declared enemy", and was withholding documentary evidence that would show the claims had no basis. To further try to clear his name, Sievwright wrote a lengthy letter to the Geelong Advertiser, the voice of the Western District squatters. Over two days in February 1845, it devoted four broadsheet pages to Sievwright's letter. It incorporated correspondence relating to the Protectorate, his views on what he viewed as its maladministration by Robinson, and the failure of La Trobe to grant his demand for a full inquiry into his dismissal. "We cannot see a man crushed, as Mr Sievwright has been, without crying 'shame'. We confess that until these disclosures were made, we always entertained a strong prejudice against Mr Sievwright, and did not scruple to express it, and we are therefore glad of the opportunity to make reparation," the Advertiser commented. In May 1845, Sievwright sailed from Melbourne to London, leaving his family in Melbourne, to put his case for an inquiry direct to the British government. He was still trying unsuccessfully at least as late as 1849. ------ 2. Selected bibliography of 3d printer The author is Henri-Jean Martin unless indicated otherwise. Les mtamorphoses du livre.

CONCRETE 3D PRINTER Introduction , Working , Types , Applications , Advantages & Disadvantages
CONCRETE 3D PRINTINGThree dimensional printing (3DP) is a manufacturing process that builds layers to create a three- dimensional solid object from a digital model. It allows for mass customization and complex shapes that cannot be produced in other ways, eliminates the need for tool production and its associated labour, and reduces waste stream. Because of these advantages, 3DP has been increasingly used in different areas. including medical, automotive, aerospace, construction, etc. 3D printing for civil structures can significantly reduce the construction time and cost.However, unlike applications of 3DP in other areas, civil structures are typically large scale, with length or height spanning hundreds of meters. They are subjected to complex loadings, including gravity, wind, seismic, etc. Therefore, it is challenging to develop suitable printing tools and materials. As a result, 3DP of civil structures is still at a primitive stage. 1. Contour crafting 2. Concrete printing 3. CON print 3DThis Three are Extrusion based techniquesThe extrusion-based technique is analogous to the fussed deposition modelling (FDM) method which extrudes cementitious material from a nozzle mounted on a gantry, crane or a 6-axes robotic arm to print a structure layer by layer.This technique has been aimed at on-site construction applications such as large-scale building components with complex geometries, and has a great potential to make a significant and positive contribution to the construction industry. A schematic of the extrusion based technique is illustrated in Figure1. Contour crafting (CC) technology has been developed at the university of Southern California, USA. This technology uses the extrusion-based technique to extrude two layers of cementitious mixture to build a vertical concrete formwork. Custom-made reinforcement ties are manually inserted between layers (at every 30 cm horizontal and 13 cm vertically) while the CC machine is constantly extruding the layers. Trowel-like Gins are attached to the print head to create smooth extruded surfaces. Once the extruded formwork is completed, concrete is then manually poured to a height of 13 cm and a second batch is poured on top of the first batch after one hour. A one hour delay batch is to control the lateral pressure of the concrete by allowing it to partially cure and harden. The chief advantagesThe superior surface finish and the greatly enhanced of fabrication. Other key advantage of CC is possibility of integration with other robotics methods for installing internal components such as pipes, electrical conductors, and reinforcement modules to enhance mechanical property. The CC technology currently produces vertical elements largely in compression. When doorway or window is required a lintel is placed to bridge the gap and the wall can be placed above. Therefore, it avoids the cantilever problem.Drawbacks for the CC technology :1.This technology is limited to vertical extrusion, hence yielding 2. 5 D topologies (vertical extension of a planar shape),2. The initial formwork and trowel system can be rather complex to implement for production, depending on the size and shape of the object being printed.3.The interrupted sequential casting of concrete within the formwork due to hydrostatic pressure and weak mechanical properties of the extruded concrete may result in weakened interfacial zones between the layers. 2. Concrete PrintingConcrete Printing technology has been developed by a team at Loughborough University in the United Kingdom. This technology also uses the extrusion-based technique and to some extent is similar to the cc technology.However, the concrete Printing technology has been developed to retain 3D freedom and has, smaller resolution of deposition, which allows for greater control of internal and external geometries In addition, the material used in Concrete Printing is a high performance fiber-reinforced fine-aggregate concrete resulting in superior material properties to those obtained in the CC technology. Concrete printing requires additional support to create overhangs and other freeform features. It use, second material, in a similar manner to the FDM method. The disadvantage of this process is that an additional deposition device is needed for the second material resulting in more maintenance, cleaning and control instructions and the secondary structure must be cleaned away in a post processing operation. Drawbacks of Concrete Printing Technology(1) The trade-off necessary for maintaining its dimensional accuracy makes the process quite slow with regards to the envisioned industrial application,(2) Although the technology initially aimed at the veneration of 3D topologies rather than 2.5 D. the use of second material to support overhangs reduces the efficiency and flexibility of the process while increasing its material cost,(3) Dimensions and possibilities in terms of shape-design are limited by the dimensions of the printing frame3. and Concrete Printing technologies, while demonstrating many technological advantages, are subjected inherent limitations such as the necessity of using new and advanced machinery, small mineral some aggregate sizes (fine-aggregate mortar rather than concrete), and limited size of the printed elements (i. e. the size of the 3D printer must be larger than the size of the element to be printed). To overcome these limitations, a novel approach for 3DCP technology for on-site construction, named CONPrint 3D, is currently being developed at the TU Dresden, Germany, which intends to bring 3DCP directly into the building sites. The main advantages of CONPrint 3D technology are high geometrical flexibility, usage of commonly used construction machinery and low dependency skilled labour.

CONCRETE 3D PRINTINGThree dimensional printing (3DP) is a manufacturing process that builds layers to create a three- dimensional solid object from a digital model. It allows for mass customization and complex shapes that cannot be produced in other ways, eliminates the need for tool production and its associated labour, and reduces waste stream. Because of these advantages, 3DP has been increasingly used in different areas. including medical, automotive, aerospace, construction, etc. 3D printing for civil structures can significantly reduce the construction time and cost.However, unlike applications of 3DP in other areas, civil structures are typically large scale, with length or height spanning hundreds of meters. They are subjected to complex loadings, including gravity, wind, seismic, etc. Therefore, it is challenging to develop suitable printing tools and materials. As a result, 3DP of civil structures is still at a primitive stage. 1. Contour crafting 2. Concrete printing 3. CON print 3DThis Three are Extrusion based techniquesThe extrusion-based technique is analogous to the fussed deposition modelling (FDM) method which extrudes cementitious material from a nozzle mounted on a gantry, crane or a 6-axes robotic arm to print a structure layer by layer.This technique has been aimed at on-site construction applications such as large-scale building components with complex geometries, and has a great potential to make a significant and positive contribution to the construction industry. A schematic of the extrusion based technique is illustrated in Figure1. Contour crafting (CC) technology has been developed at the university of Southern California, USA. This technology uses the extrusion-based technique to extrude two layers of cementitious mixture to build a vertical concrete formwork. Custom-made reinforcement ties are manually inserted between layers (at every 30 cm horizontal and 13 cm vertically) while the CC machine is constantly extruding the layers. Trowel-like Gins are attached to the print head to create smooth extruded surfaces. Once the extruded formwork is completed, concrete is then manually poured to a height of 13 cm and a second batch is poured on top of the first batch after one hour. A one hour delay batch is to control the lateral pressure of the concrete by allowing it to partially cure and harden. The chief advantagesThe superior surface finish and the greatly enhanced of fabrication. Other key advantage of CC is possibility of integration with other robotics methods for installing internal components such as pipes, electrical conductors, and reinforcement modules to enhance mechanical property. The CC technology currently produces vertical elements largely in compression. When doorway or window is required a lintel is placed to bridge the gap and the wall can be placed above. Therefore, it avoids the cantilever problem.Drawbacks for the CC technology :1.This technology is limited to vertical extrusion, hence yielding 2. 5 D topologies (vertical extension of a planar shape),2. The initial formwork and trowel system can be rather complex to implement for production, depending on the size and shape of the object being printed.3.The interrupted sequential casting of concrete within the formwork due to hydrostatic pressure and weak mechanical properties of the extruded concrete may result in weakened interfacial zones between the layers. 2. Concrete PrintingConcrete Printing technology has been developed by a team at Loughborough University in the United Kingdom. This technology also uses the extrusion-based technique and to some extent is similar to the cc technology.However, the concrete Printing technology has been developed to retain 3D freedom and has, smaller resolution of deposition, which allows for greater control of internal and external geometries In addition, the material used in Concrete Printing is a high performance fiber-reinforced fine-aggregate concrete resulting in superior material properties to those obtained in the CC technology. Concrete printing requires additional support to create overhangs and other freeform features. It use, second material, in a similar manner to the FDM method. The disadvantage of this process is that an additional deposition device is needed for the second material resulting in more maintenance, cleaning and control instructions and the secondary structure must be cleaned away in a post processing operation. Drawbacks of Concrete Printing Technology(1) The trade-off necessary for maintaining its dimensional accuracy makes the process quite slow with regards to the envisioned industrial application,(2) Although the technology initially aimed at the veneration of 3D topologies rather than 2.5 D. the use of second material to support overhangs reduces the efficiency and flexibility of the process while increasing its material cost,(3) Dimensions and possibilities in terms of shape-design are limited by the dimensions of the printing frame3. and Concrete Printing technologies, while demonstrating many technological advantages, are subjected inherent limitations such as the necessity of using new and advanced machinery, small mineral some aggregate sizes (fine-aggregate mortar rather than concrete), and limited size of the printed elements (i. e. the size of the 3D printer must be larger than the size of the element to be printed). To overcome these limitations, a novel approach for 3DCP technology for on-site construction, named CONPrint 3D, is currently being developed at the TU Dresden, Germany, which intends to bring 3DCP directly into the building sites. The main advantages of CONPrint 3D technology are high geometrical flexibility, usage of commonly used construction machinery and low dependency skilled labour.

Introduction to 3d Printer
Introduction to 3d Printer
1. Protector of Aborigines of 3d printer After arriving in Sydney in November 1838, Sievwright lived briefly with his wife, Christina, and their seven children in Melbourne. The whole family then moved to live among the Aborigines in the Geelong area. This was on the edge of the area assigned to him, known as the Western District, covering about 40,000 square kilometres. British and Irish settlers had begun arriving in the District about three years earlier, but at the time thousands of Aboriginal people still far outnumbered the Europeans. As a Protector of Aborigines, Sievwright was commissioned by the British government to represent the Aboriginal people, and to protect them "from cruelty, oppression and injustice" and "from encroachments upon their property". In February 1841, Sievwright and his family moved further into his district to set up a new camp at Lake Keilambete, near present-day Terang. A year later, he moved to Mt Rouse, near present day Penshurst, again urging the Aborigines of the district to join him. Sievwright's difficulties were considerable, not speaking the languages of the Aborigines under his care, and most of them coming into contact with Europeans for the first time. Nevertheless, at each of his camps he launched limited agricultural training programs in return for food, when traditional food supplies became scarcer as more European settlers arrived with sheep and cattle. At the same time, he launched a series of investigations into the killing of Aboriginal people. His efforts to seek prosecutions of Europeans involved in killings made him extremely unpopular among the white settlers. One squatter recorded in his private journal that by February 1840, Sievwright had already become "the most unpopular man that ever breathed". Around the same time, the Port Phillip Gazette reported that Sievwright was "in very bad odour" with the squatters of the Western District. "These gentlemen, it appears, cut him upon all occasions, and will not suffer him to enter their houses." In August 1842, Sievwright was told that he'd been suspended without pay because of charges against his moral character, dating back to 1839. Port Phillip's Superintendent Charles La Trobe told NSW Governor George Gipps in Sydney that even if the charges against Sievwright were false, they had been "from the outset fatal to him and his recent career". Chief Protector Robinson had already backed a plan to sack Sievwright months earlier. Even before Sievwright learned of his suspension at Mt Rouse, it had been reported in Melbourne by the Port Phillip Gazette. At the same time, the Gazette referred to a threat by the colonial government to refuse squatting licences in part of the Western District where Sievwright had reported the recent murders of three Aboriginal women and a child. "There is still some doubt if the whole affair has not been exaggerated," it said. After it became apparent that Sievwright's suspension was based at least in part on a letter written by his own wife in 1839, both she and their eldest daughter, Frances, wrote to La Trobe defending him.However, Sievwright remained suspended, and the family slipped into poverty. "Mr Sievwright's situation precluded him from making friends among the white population," a man called Frederic Nesbitt wrote to La Trobe. "Therefore they are now suffering the penalty of having done their duty to the Aborigines." Geelong Police Magistrate Nicholas Fenwick confirmed the family's plight, telling the Superintendent: "Nobody here it appears will give them anything on credit now that Mr Sievwright has been suspended, and how they manage to get their daily bread, nobody can tell, and their children are in rags." In London, Secretary of State for War and the Colonies, Edward Smith-Stanley, endorsed Gipps' recommendation that Sievwright be dismissed. "I should wish if possible to avoid pursuing this matter further, as it is not of a character fit for public investigation," he told the Governor. La Trobe and Gipps continued to reject Sievwright's demands for a full inquiry into the allegations that had led to his dismissal. They agreed only to two inquiries into subsequent claims raised in 1844 that he'd misappropriated government stores. Sievwright told La Trobe he regretted to state that Chief Protector Robinson was his "openly declared enemy", and was withholding documentary evidence that would show the claims had no basis. To further try to clear his name, Sievwright wrote a lengthy letter to the Geelong Advertiser, the voice of the Western District squatters. Over two days in February 1845, it devoted four broadsheet pages to Sievwright's letter. It incorporated correspondence relating to the Protectorate, his views on what he viewed as its maladministration by Robinson, and the failure of La Trobe to grant his demand for a full inquiry into his dismissal. "We cannot see a man crushed, as Mr Sievwright has been, without crying 'shame'. We confess that until these disclosures were made, we always entertained a strong prejudice against Mr Sievwright, and did not scruple to express it, and we are therefore glad of the opportunity to make reparation," the Advertiser commented. In May 1845, Sievwright sailed from Melbourne to London, leaving his family in Melbourne, to put his case for an inquiry direct to the British government. He was still trying unsuccessfully at least as late as 1849. ------ 2. Selected bibliography of 3d printer The author is Henri-Jean Martin unless indicated otherwise. Les mtamorphoses du livre.

Startups Use SLS 3D Printers to Enter the Market
Startups Use SLS 3D Printers to Enter the Market
Trends of the global startups market show that the era of virtual ventures is in the downturn. Now it is time for advanced manufacturing. With that in mind, business owners are looking for reliable and inexpensive tools for prototyping. We are living in the global startup revolution era. According to the Startup Genome Report, venture capital investments in startups hit $140 billion invested in 2017. It was the decade high. As this sector is growing about 25% every two years, we can observe some crucial shifts inside it. Companies that were on the rise at the beginning of the startup era, focused mainly on digital media, social media apps, and other strictly internet based companies are declining. Now it is time for blockchain, advanced manufacturing, and artificial intelligence.Advanced manufacturing is the futureWhy is that? Internet-based companies used to be the first choice for the new business owners because of being inexpensive. At least at the beginning. It was easier to buy a domain, learn Wordpress a little bit and create a value proposition to potential customers. US Small Business Administration reports that most microbusinesses cost around $3,000.That is way it was a boom for companies offering services instead of real products. When it comes to the production, the steep road ahead effectively deterred future entrepreneurs.- There are a lot of factors to take into account when you are hitting the market with the real product says Konrad Glowacki, one of the Co-Founders of Sinterit. Costs effectiveness is crucial. When we established Sinterit in 2014, it was a startup too. Time and money are two agents you need to control wisely he adds.Prototyping is a one of the areas that are causing the most problems. You needed to order a lot of elements to keep it cheap. But for startup owners, it could be way too risky.Prototyping the problem solvedFor years, the only way to make useful prototype was to order samples made by CNC machines. It took a lot of time (12 weeks per part), was costly and needed a lot of knowledge in designing pieces. Another possibility was injection molding, but way more expensive and consuming a lot of time, from 2 to 8 weeks. In this environment starting an internet-based business seemed to be less problematic.Three factors that changed the startup environmentEverything changed when 3D printers become popular. Those machines lowered not only the prototyping costs but also shortened the time needed to produce the final element.With a lot of possible options, startup owners were looking for the most available ones, like basic 3D printers. For simple, uncomplicated and undemanding products it seemed to be a perfect solution. But for more sophisticated ones, with a lot of little parts that need to be both precise and durable, the limitations of the most popular machines become more visible. Low accuracy and demanding post-processing frighten some start-uppers. There is always an option of sending production files to service providers. But new business owners who are devoutly concerned with the security and copyright protection issues are not likely to do so.Desktop SLSA lot of those concerns ended with the development of the desktop SLS 3D printing branch. With companies like Sinterit, the producer of Sinterit Lisa and Lisa PRO, prototyping process become available for almost everyone. Three most common barriers holding potential business owners from entering the SLS world become the history.With the price even 20th times lower than the industrial machines, desktop SLS 3D printers started to appear in the design offices more often.That also dealt with the second stopper, which was the space needed to place the printer in house. Now you can put it on the desk, literally next to your laptop.And the third one, the ease of use was a game changer. As the industrial 3D printers need a trained operator, desktop machines are so easy to operate, with integrated software included in its price. You need a little knowledge to start printing. Not to mention that after the process ends, you just need to get rid of the remaining powder and thats it. Without shipping costs and waiting time.Startups choose SLS 3D printersHistory shows that even the most prominent companies like Microsoft or Apple were settled in the garage. When you have your genuinely original idea, you dont need a production plant to test it. The day to scale your business will come sooner or later.Owning an affordable SLS printer is the first step to develop functional prototypes, arrange some test or even prepare for a crowdfunding campaign. It is easier to get funding for a real product rather than use the most beautiful render. For Sebastian Religa, CTO in LOCKY, the worlds first smart key overlay producer, it was crucial.- We decided to use Sinterit Lisa to make a functional prototype for LOCKY. We needed a reliable tool to produce the first examples of our device that will have the characteristics of the final product says Sebastian Religa. Using desktop SLS 3D printer we got the best precision of every detail, fast production time and the most cost-effective solution he adds.It took about 18 hours to print four sets of LOCKY, ready to put the key inside and test all of the functions. Sinterit Lisa can print even 16 complete sets in one go

They are sometimes tested (on an annual basis) by the physical plant or occupational health and safety people at an institution, and Ive seen it done under these conditions. And of course they are used (rarely) for actual emergencies. But the best story I know is this: A friend of mine, who will remain unnamed, while a new technician at a university that shall remain unnamed, asked about the emergency shower outside the lab. Other folks in the lab challenged the new tech to give the handle a pull. (I expect that they were expecting her to get soaked, and that they thought itd be a fine practical joke to play on the newbie.) Challenge accepted! The valve broke, and the shower could not be turned off. There was no drain beneath the shower. Water began to flood the building from an upper floor. It turns out that somebody neglected to put a cutoff valve on the emergency water supply. Water had to shut off at a valve on a main that supplied a reasonably large area. This took some time. Meanwhile, water was flowing at high volume. Considerable damage ensued. Honestly, officer, some guy weve never seen before wandered through the hall, pulled the shower handle, and ran!
Why 3D Printer Manufacturers Should NEVER Make Software
Why 3D Printer Manufacturers Should NEVER Make Software
Have you heard of Pirate3Ds Buccaneer 3D Printer?Its the Jony Ives-inspired 3D printer that never took sail.With a sleek, aluminum body, smooth, crystal clear acrylic housing, and beautiful aesthetics, its all beauty and no brains.If you arent in the loop, Pirate3D raised a (then) record-breaking $1. 4M on Kickstarter for their Buccaneer 3D Printer in 2013.It was a hit.Largely because most consumers had never seen such a well thought out 3D printer at such an affordable price point.At the time, the most well-known printer was Makerbots Replicator 2, which ran for $2,200 and Pirate3D claimed to have a better designed, faster printer (The Buccaneer) for just $347. Truth is: it WAS a well-designed printer and we were just as excited for Pirate3D to pull this off.Not only that, Pirate3D was ambitious enough to pitch an entire 3D printing ecosystem, instead of just a 3D printer.They claimed to have a cloud-based component to the Buccaneer 3D printer called Treasure Island that would allow users to directly send 3D printable objects into their printer from any web-enabled device. It makes a lot of sense and the guys at Pirate3D were definitely thinking about the importance of having a source for rich 3D printable content.Thats not all.They also claimed to deliver something called Smart Objects which was supposed to be an idiot-proof 3D design software that anyone could easily use without having any specialized training.With Smart Objects, anyone without design experience could easily manipulate and customize 3D models according to their own needs before printing them. Again, this is all well thought out and I tip my hat to the Pirate3D founders for their boldness and ambition.With that said, the biggest reason, I believe, that Pirate3D struggled to deliver printers and eventually failed is because of a tremendous lack of focus.Manufacturing 3D printers is not an easy task and people underestimate the difficulty of engineering hardware. Not to mention, there are countless successfully funded 3D printers on Kickstarter that failed to deliver the printers. (Remember ez3Ds Phoenix 3D Printer? Or how about Duy Dangs Eventerbot?)Keep in mind, this does not even include the gargantuan task of building a software-driven ecosystem around the printer (i.e: Smart Objects, Treasure Island etc.).To make it even more difficult, it was going to be executed by recent college graduates with zero experience in business or manufacturing. . .Its just that the current design has heavy costs because it was designed by 3 fresh graduates with no training in industrial design and manufacturing two years ago Brendan Goh, Co-Founder of Pirate3DKeep in mind, this company failed after raising an additional $2 million dollar investment.In my opinion, 3D printer manufacturers should focus their energy on hardware, not softwareThere are benefits to being a jack of all trades, but, when it comes to technology, it is often best to stick to ones expertise and focus on one area.In fact, Pirate3D is an excellent real-world case study highlighting that fact. Do you see Lamborghini trying to get into consumer washing machines or Apple coming out with a new line of breakfast cereal? Nope.Building a software-driven ecosystem for consumer 3D printers is an incredibly complex task.Which is why it should only be left for companies with expertise in software. (like us)Personally, I have been advocating for 3D printer manufacturers building their own 3D printer operating systems for this exact reason. In fact, in August 2015, I even used Pirate3D as an example of a company that is contributing to the market fragmentation of 3D printer software.Not only that, Brendon from Pirate3D seems to agree with me:. .Developing an entire ecosystem of our own combination of hardware, software and library was a far more costly engineering project than expected Brendan Goh, Co-Founder of Pirate3DWhen 3D printer manufacturers lose focus and start branching off into software, the result is an incessantly fragmented marketplace filled with complex software and lack of compatibility.In Pirate3Ds case, a potentially successful Kickstarter that went belly up, leaving most of their backers empty-handed.If you are a 3D Printer manufacturer interested in making your printers easy-to-use, we can help. Our expertise is in software engineering for 3D Printing, and as the fastest growing cloud platform in 3D Printing, weve learned a LOT about the industry throughout the years.Let us help you make your 3D Printers even more useful and easier to use by helping you engineer the software (embedded or otherwise) that ships with your printers.If you are curious about specific questions, simply get in touch with us. Dilanka. RELATED QUESTION Whats the first thing one should do if they accidentally sprayed insect killer spray on their eyes? Flush with water. Almost universally, when you get something in your eyes, flushing with water is the first step - thats why you see those emergency eye wash stations in chemistry labs. Check the label before you use it (because if that happens, you may not be able to read the label). Some are more dangerous than others and may direct you to take additional steps, but in some cases, a good flushing may be all you need. Example: Ortho Home Defense - If in eyes: flush with plenty of water. See a doctor if irritation persists.

CONCRETE 3D PRINTER Introduction , Working , Types , Applications , Advantages & Disadvantages
CONCRETE 3D PRINTINGThree dimensional printing (3DP) is a manufacturing process that builds layers to create a three- dimensional solid object from a digital model. It allows for mass customization and complex shapes that cannot be produced in other ways, eliminates the need for tool production and its associated labour, and reduces waste stream. Because of these advantages, 3DP has been increasingly used in different areas. including medical, automotive, aerospace, construction, etc. 3D printing for civil structures can significantly reduce the construction time and cost.However, unlike applications of 3DP in other areas, civil structures are typically large scale, with length or height spanning hundreds of meters. They are subjected to complex loadings, including gravity, wind, seismic, etc. Therefore, it is challenging to develop suitable printing tools and materials. As a result, 3DP of civil structures is still at a primitive stage. 1. Contour crafting 2. Concrete printing 3. CON print 3DThis Three are Extrusion based techniquesThe extrusion-based technique is analogous to the fussed deposition modelling (FDM) method which extrudes cementitious material from a nozzle mounted on a gantry, crane or a 6-axes robotic arm to print a structure layer by layer.This technique has been aimed at on-site construction applications such as large-scale building components with complex geometries, and has a great potential to make a significant and positive contribution to the construction industry. A schematic of the extrusion based technique is illustrated in Figure1. Contour crafting (CC) technology has been developed at the university of Southern California, USA. This technology uses the extrusion-based technique to extrude two layers of cementitious mixture to build a vertical concrete formwork. Custom-made reinforcement ties are manually inserted between layers (at every 30 cm horizontal and 13 cm vertically) while the CC machine is constantly extruding the layers. Trowel-like Gins are attached to the print head to create smooth extruded surfaces. Once the extruded formwork is completed, concrete is then manually poured to a height of 13 cm and a second batch is poured on top of the first batch after one hour. A one hour delay batch is to control the lateral pressure of the concrete by allowing it to partially cure and harden. The chief advantagesThe superior surface finish and the greatly enhanced of fabrication. Other key advantage of CC is possibility of integration with other robotics methods for installing internal components such as pipes, electrical conductors, and reinforcement modules to enhance mechanical property. The CC technology currently produces vertical elements largely in compression. When doorway or window is required a lintel is placed to bridge the gap and the wall can be placed above. Therefore, it avoids the cantilever problem.Drawbacks for the CC technology :1.This technology is limited to vertical extrusion, hence yielding 2. 5 D topologies (vertical extension of a planar shape),2. The initial formwork and trowel system can be rather complex to implement for production, depending on the size and shape of the object being printed.3.The interrupted sequential casting of concrete within the formwork due to hydrostatic pressure and weak mechanical properties of the extruded concrete may result in weakened interfacial zones between the layers. 2. Concrete PrintingConcrete Printing technology has been developed by a team at Loughborough University in the United Kingdom. This technology also uses the extrusion-based technique and to some extent is similar to the cc technology.However, the concrete Printing technology has been developed to retain 3D freedom and has, smaller resolution of deposition, which allows for greater control of internal and external geometries In addition, the material used in Concrete Printing is a high performance fiber-reinforced fine-aggregate concrete resulting in superior material properties to those obtained in the CC technology. Concrete printing requires additional support to create overhangs and other freeform features. It use, second material, in a similar manner to the FDM method. The disadvantage of this process is that an additional deposition device is needed for the second material resulting in more maintenance, cleaning and control instructions and the secondary structure must be cleaned away in a post processing operation. Drawbacks of Concrete Printing Technology(1) The trade-off necessary for maintaining its dimensional accuracy makes the process quite slow with regards to the envisioned industrial application,(2) Although the technology initially aimed at the veneration of 3D topologies rather than 2.5 D. the use of second material to support overhangs reduces the efficiency and flexibility of the process while increasing its material cost,(3) Dimensions and possibilities in terms of shape-design are limited by the dimensions of the printing frame3. and Concrete Printing technologies, while demonstrating many technological advantages, are subjected inherent limitations such as the necessity of using new and advanced machinery, small mineral some aggregate sizes (fine-aggregate mortar rather than concrete), and limited size of the printed elements (i. e. the size of the 3D printer must be larger than the size of the element to be printed). To overcome these limitations, a novel approach for 3DCP technology for on-site construction, named CONPrint 3D, is currently being developed at the TU Dresden, Germany, which intends to bring 3DCP directly into the building sites. The main advantages of CONPrint 3D technology are high geometrical flexibility, usage of commonly used construction machinery and low dependency skilled labour.

RELATED QUESTION Have you ever known/seen someone have to use the emergency shower in science labs? They are sometimes tested (on an annual basis) by the physical plant or occupational health and safety people at an institution, and Ive seen it done under these conditions. And of course they are used (rarely) for actual emergencies. But the best story I know is this: A friend of mine, who will remain unnamed, while a new technician at a university that shall remain unnamed, asked about the emergency shower outside the lab. Other folks in the lab challenged the new tech to give the handle a pull. (I expect that they were expecting her to get soaked, and that they thought itd be a fine practical joke to play on the newbie.) Challenge accepted! The valve broke, and the shower could not be turned off. There was no drain beneath the shower. Water began to flood the building from an upper floor. It turns out that somebody neglected to put a cutoff valve on the emergency water supply. Water had to shut off at a valve on a main that supplied a reasonably large area. This took some time. Meanwhile, water was flowing at high volume. Considerable damage ensued. Honestly, officer, some guy weve never seen before wandered through the hall, pulled the shower handle, and ran!

3D Printer That Can Print Human Skin: Spanish Scientists ...
Spanish scientists have developed a prototype 3D bioprinter to produce functional human skin. Picture: Universidad Carlos III de MadridSource:SuppliedPRETTY soon if your skin becomes wrinkly, saggy or damaged you might just be able print yourself some new skin to patch up your ageing body. It may be the biggest human organ, but its about to become a lot less finite.Thats because scientists in Spain have developed a prototype for a 3D bioprinter that is capable of producing totally functional human skin.The skin can be used for research purposes, testing cosmetics and other chemical-based products, and for transplanting onto human patients.(It) can be transplanted to patients or used in business settings to test chemical products, cosmetics or pharmaceutical products in quantities and with timetables and prices that are compatible with these uses, said Jos Luis Jorcano, one of the researchers behind the project.This new version of human skin is one of the first living human organs created using bioprinting to be introduced to the marketplace, according to Phys.org.The endeavour is a collaboration between scientists at Universidad Carlos III de Madrid (UC3M) and bio-engineering company BioDan Group which specialises in regenerative medicine with a particular focus on skin.The material the printer produces mimics the structure of skin, with the inside layer consisting of fibroblasts that produce collagen, the protein that gives elasticity and mechanical strength to the skin.As well as medical applications, one day a similar product could conceivably be used in robotics as the lifelike epidermis of our eventual robot companions.Printable human skin could come in handy in some surprising ways.Source:SuppliedThis method of bioprinting allows skin to be generated in a standardised, automated way, and the process is less expensive than manual production, Alfredo Brisac, CEO of BioDan Group claimed.The research was published recently in the electronic version of the scientific journal Biofabrication.As the authors note, significant progress has been made over the past 25 years in the development of in vitro-engineered substitutes for skin, but bioprinters could make it much easier to produce such materials in a more cost effective way.3D bioprinting has emerged as a flexible tool in regenerative medicine, the authors wrote.In the present study, we have used this technique to print a human bilayered skin using bioinks containing human plasma as well as primary human fibroblasts and keratinocytes that were obtained from skin biopsies.These results demonstrate that 3D bioprinting is a suitable technology to generate bioengineered skin for therapeutical and industrial applications in an automatised manner.
