3D Printing Definition and Timeline
Paul provided the following definition and timeline:
3D printing–also known as additive manufacturing or positive manufacturing–is a process of making a three dimensional solid object of virtually any shape from a digital model.
- 70’s Stereo Lithography (SLA) laser cured liquid photo polymer (3D Systems / NYSE:DDD)
- 80’s Fusion Deposition Modeling (FDM) melting plastic filament (Stratasys Inc / NASDAQ:SSYS)
- 80’s Selective Laser Sintering (SLS) for metal, ceramics, or plastics, etc…
- 90’s Rapid Prototyping service bureaus became available: Raychem,Quickparts, SolidConcepts, etc…
- 2007 Reprap homegrown (FDM) “self-replicating” printer hits open source maker movement (See RepRap Family Tree)
- 2012 consumer level printers hit the mainstream media
- 2013 MakerBot makes the Today Show, 3D Systems “Cube” sold at Staples.
