3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Chuck Hull (Charles W. Hull; born May 12, 1939) is an American inventor who is the co-founder, executive vice president and chief technology officer for regenerative medicine [1] of 3D Systems. [2] [3] He is one of the inventors of the SLA 3D printer, the first commercial rapid prototyping technology, and the widely used STL file format.
Several 3D printing processes have been invented since the late 1970s. [3] The printers were originally large, expensive, and highly limited in what they could produce. [4] Evolution of 3D printing over the decades. [3] A large number of additive processes are now available.
S. Scott Crump (born Steven Scott Crump) is the inventor of fused deposition modeling (FDM) and co-founder of Stratasys, Ltd. Crump invented and patented FDM technology in 1989 with his wife and Stratasys co-founder Lisa Crump.
Carl Robert Deckard, Ph.D, ME (1961 - December 23, 2019) was an American inventor, teacher, and businessman, best known for inventing and developing Selective Laser Sintering (SLS), a method of 3D printing. [1] He died at the age of 58, on 23 December 2019. [2]
Unlike stereolithography, the printing process is continuous. The inventors claim that it can create objects up to 100 times faster than commercial three dimensional (3D) printing methods. [1] [2] [3]
Both are complete systems for translating 3D computer models into G-code, the machine language that commands the printer. Later, other programs like Slic3r and Cura were created. Recently, the Franklin firmware was created to allow RepRap printers to be used for other purposes such as milling and fluid handling. [16]
The first 3D printing (additive manufacturing) was used in 1983 by an American inventor, Charles (Chuck) W. Hull, to make industrial components.It is unknown when 3D printing technology entered India, but the earliest reference to 3D printing in India is when Imaginarium company started making jewellery via 3D printing technology. 3D printing has been rapidly used in many industries in India ...
