Who Invented 3D Printing?
In May 1981, Dr Hideo Kodama at the Nagoya Municipal Industrial Research Institute published details concerning a ‘rapid prototyping‘ technique. This research was the first piece of literature to describe the layer-by-layer approach so intrinsic to 3D printing. His research involved printing photopolymers using a method which preceded stereolithography, and also spoke about cross-sectional slices of layers which lay on top of each other to form the 3D object. However, Dr Kodama didn’t fulfil...
1984 – 87: Early History of 3D Printing & Invention of Stereolithography
Three years later in 1984, three French engineers named Alain Le Méhauté, Olivier de Witte, and Jean Claude André filed a patent for the Stereolithography process. They were to pioneer a new manufacturing process that was to revolutionize manufacturing! But it wasn’t to be. The three men abandoned the patent soon after they filed it, citing ‘lack of business perspective.’ In hindsight, I’m sure they’re gutted. Just three weeks after the French engineers, Charles ‘Chuck’ Hull filed his patent...
1988 – 92: Stratasys, EOS, and FDM and SLS to Rival SLA
Stereolithography had competition in the 3D printing space however, with rival processes in development. In 1988, Carl Deckard at the University of Texas filed a patent for Selective Laser Sintering(SLS) technology. Instead of using a UV light, SLS used a laser to trace and solidify layers of powder polymers. This innovative new technology was then leased to DTM Inc to use. Then it became a three-horse race. Scott Crump co-founded Stratasys in 1989 and filed the patent for Fused Deposition Mo...
The first ten years of the history of 3D printing led to the birth of future giants such as 3D Systems, Stratasys, and EOS. Still, in the mid-1990s, they were relative minnows compared to the billion-dollar valuations they now possess.
A patent expired between end tail end of 2008 and the beginning of 2009. Big deal, patents expire all the time right? This patent was owned by a now-very-large company called Stratasys, for Fused Deposition Modeling technology. FDM is the simplest 3D printing technology; it involves heating up a plastic filamentuntil it melts, and then extrudes it ...
Hideo Kodama was a Japanese researcher who published a paper on layer-by-layer 3D printing in 1981, but did not patent it. Learn how his work influenced the development of stereolithography and other 3D printing technologies.
Mar 1, 2017 · Learn about Hideo Kodama, the Japanese doctor who filed the first patent for a 3D printing system in 1980. Discover how his invention inspired other researchers and led to the creation of stereolithography and other 3D printing processes.

Mar 14, 2019 · Hideo Kodama of Japan was the first to describe how photopolymers can be used to create solid prototypes in 1981. He was not the inventor of the first 3D printer, which was designed by Chuck Hull in 1984.
Mar 20, 2019 · This was based upon the exposure of reactive monomer systems to the intersection of radiation beams, which following a direct or indirect polymerisation process, produced a sensible 3D object or solid structure. 1 A few years later in 1980, Hideo Kodama filed a patent application for a 3D printing process (for rapid prototyping), which was ...

3D printing’s roots began with the inventive efforts of Dr. Hideo Kodama. In 1981, he laid the foundation for additive manufacturing. Dr. Kodama, working at the Nagoya Municipal Industrial Research Institute, developed a system for creating three-dimensional objects through a layer-by-layer approach using photosensitive resins.
