The 3D printing process builds a three-dimensional object from a computer-aided design (CAD) model,
usually by successively adding material layer by layer, which is why it is also called additive manufacturing unlike “conventional machining”,
casting and forging processes, where material is removed from a stock item (subtractive
manufacturing) or molding and shaping by means of dies, presses and hammers.
The brief history
Beginning...
Over 40 years of past.
In 1981, “Hideo Kodama” of Nagoya Municipal Industrial Research Institute published his account of a
functional rapid-prototyping system using
photopolymers ( A solid, printed model was built up in layers, each of which corresponded to a cross-
sectional slice in the model.
FDM printers use a thermoplastic filament, which is heated to its melting point and then extruded, layer by layer, to create a three
dimensional object. The technology behind FDM was invented in the 1980s by Scott Crump, co-founder and chairman of Stratasys Ltd.
Three years later, in 1984, Charles Hull made 3D- printing history by inventing stereolithography.
In 2005, Dr. Adrian Bowyer’s RepRap Project launched an open-source initiative to create a
3D printer that could basically build itself.
In 1999 the first 3D-printed organ was implanted in humans. Scientists at Wake Forest Institute for
Regenerative Medicine printed synthetic scaffold of human bladder.
By the mid-2000s, the democratization of manufacturing had captured the public’s
imagination, as had the idea of mass
customization . The first SLS machine became commercially viable in 2006, which opened
the door to on-demand manufacturing of industrial parts. 3D-printing startup Objet
(now merged with Stratasys).
While the price of 3D printers has fallen rapidly and the accuracy of 3D printing has improved, innovators are pushing the envelope in ways that Charles Hull could only dream of. Designers are no longer limited to printing
with plastic.We can now print the engagement ring of your dreams using
GOLD,SILVER! and other metals.
