  • 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
