Thanks to personal computing developing into a revolutionary innovation in the early 1970s, 3D printing was made possible in the late 1980’s. 3D printing technology was at one point only available for the business elites because of its high cost and limited production by few companies. This technology in the the late 1980s began as a new additive manufacturing, changing and speeding up what use to be subtractive manufacturing. Subtractive manufacturing relied on tooling and assembly lines since it began, 3D printing however made it possible for companies to fabricate prototypes on demand. However 3D printing is no longer limited to manufacturing, but has developed into various categories as printer cost continue to go down, making it more…show more content…
Stephanie Crawford says SLA Printers work by a focused beam of UV rays on the surface of the object to be recreated. The CAD designed object is filled with what 's called resin (photopolymer). When the light hits the resin, the liquid hardens to form a high resolution 3D model of the object that you designed. Hull, a few years later co found 3D Systems Corporation, one of the first companies to sell a high end 3D printer and still is one of the leading companies with this technology today. Charles Hull’s first RP system, the SLA-1, was revealed in 1987 and quickly followed ongoing testing until this system was sold in 1988. As always after new technology is discovered, there is always new competition, in 1987, Carl Deckard, who at the time was working for University of Texas, filed a patent in the US for the Selective Laser Sintering (SLS). SLS method is somewhat similar to stereolithography (SLA) but instead of using liquid resin, you can use powdered material in the instead. SLS made it possible to use a variety of materials ceramics, nylon, aluminum, glass and steel or silver. In 1989 another new Printing process was invented by Scott Crump, he too co found a leading company today Stratasys Inc. Scotts process was called Fused Deposition Modelling (FDM). This process is what is widely used by beginners in 3D printing do to its easy refillable and cheap material. FDM works by melted thermoplastic materials joined together in
