Subtractive vs. Additive Manufacturing Subtractive (Traditional) Manufacturing CNC routers, drills, lathes, saws, etc. Start with something big and work your way down Examples: Carving a statue, cookie cutters Additive Manufacturing (AM) “3D printers” (FFF, SLA, SLS, DMLS, Polyjet) Start with nothing, build up layer by layer Examples: Laying bricks, painting a picture
Method: Fused Filament Fabrication (FFF) Material: Thermoplastic Filament
Method: Stereolithography (SLA) Material: Photoreactive resin
Material: Photocurable Resin Method: Polyjet Material: Photocurable Resin
Method: Direct Metal Laser Sintering Material: Powdered Metal
