6 Historical Development In 3D Printing Technology

Hideo Kodama's Rapid Prototyping System (1981)

This is where it all began. Hideo Kodama of Nagoya Municipal Industrial Research Institute was the first to describe a functional rapid-prototyping system using photopolymers.

Chuck Hull, the co-founder of 3D Systems, invented the Stereolithography Apparatus (SLA). This technology uses a UV laser to solidify layers of photopolymer resin, creating a 3D object.

Carl Deckard, a student at the University of Texas, developed the Selective Laser Sintering (SLS) technology. This process involves using a laser to sinter powdered material, binding it together to create a solid structure.

Scott Crump's Fused Deposition Modeling (1988)

This technology uses a plastic filament or metal wire which is unwound from a coil, supplying material to produce a part.

EOS, a German company, introduced the Stereos technology, an industrial 3D printing process that builds parts layer-by-layer using a laser to melt and solidify a metal powder.

3D Systems' MultiJet Printing (1996)

3D Systems introduced MultiJet Printing (MJP) which is a similar process to SLA, but it uses a jet to spray the photopolymer material onto a build platform.
