A liquid photopolymer in a vat is selectively cured by light- activated polymerization
Thermal energy - laser or electron beam, selectively melts regions of powder into a 3D shape
Selectively deposit liquid droplets to join powder materials into a part
Selectively deposit droplets to build a 3D shape
Sheets of materials are bonded to form a 3D shape
Extrudes material through a nozzle to a final 3D shape
Focused thermal energy is used to melt material as the material itself is deposited
