What are the 7 categories of additive manufacturing?
There are seven additive manufacturing types in the ISO/ASTM 52900 standard: Material extrusion: an additive manufacturing process in which material is selectively dispensed through a nozzle or orifice Material jetting: an additive manufacturing process in which droplets of build material are selectively deposited Binder jetting: an additive manufacturing process in which a liquid bonding agent is selectively deposited to join powder materials Sheet lamination: an additive manufacturing process in which sheets of material are bonded to form a part Vat photopolymerization: an additive manufacturing process in which liquid photopolymer in a vat is selectively cured by light-activated polymerization Powder bed fusion: an additive manufacturing process in which thermal energy selectively fuses regions of a powder bed Directed energy deposition: an additive manufacturing process in which focused thermal energy is used to fuse materials by melting as they are being deposited
