I was lucky enough to be 1st employee of 3D Systems, the company which invented 3D printing way back in '87. I designed and built the prototypes of the first commercial printer, the SLA-250, with my own hands. I NEVER thought then that some of the things being printed now would ever be possible. |

Amazing, never released their history went back so far, chicklewis |

I witnessed 3D printing at the U.S. Naval Academy back in 1980… |

Tell us more about that, if you would, please, nudspinespittle. To which technology are you referring? |

Are you in the documentary "Printing a Legend"? |
| chicklewis | 06 Jul 2015 7:07 a.m. PST |
I've never seen "printing a legend", davenbak, so it is unlikely I'm in it. I'll go find and watch it, though. (Edit: International Movie Database has never heard of "Printing a Legend" and google searches come up empty. Perhaps a variation on the title?) |

Probably Print the Legend?

Heres what wikipedia says on the early history on 3d printing:
Earlier Additive Manufacturing (AM) equipment and materials were developed in the 1980s. In 1981, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two AM fabricating methods of a three-dimensional plastic model with photo-hardening polymer, where the UV exposure area is controlled by a mask pattern or the scanning fiber transmitter. Then in 1984, Chuck Hull of 3D Systems Corporation developed a prototype system based on this process known as stereolithography, in which layers are added by curing photopolymers with ultraviolet light lasers. Hull defined the process as a "system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed," but this had been already invented by Kodama. Hull's contribution is the design of the STL (STereoLithography) file format widely accepted by 3D printing software as well as the digital slicing and infill strategies common to many processes today. |

Yes, Chuck Hull, for whom I had worked previously, invited me to be employee #1 of 3D Systems. I had not heard about Hideo Kodama's work, but he apparently didn't do anything to commercialize the ideas. |
