2.1 AM processes According to ISO/ASTM there are currently seven AM process categories that result in a 3D CAD model being formed into a solid , integrated part : Binder jetting : droplet printing of a liquid used to bind powder particles together ; Directed energy deposition : material is simultaneously fed into a moving focused energy region ; Material extrusion : material is fed through a nozzle in a liquid state after which solidifies ; Material jetting : material is jetted in liquid droplet form after which it solidifies ; Powder bed fusion : powder material is selectively heated so that the particles partially or fully melt to form a solid matrix ; Sheet lamination : sheets of material are bonded together either before or after the part outline is separated from the sheets ; Vat photopolymerisation : a platform is dropped through or raised above a vat of liquid resin where light is used to selectively solidify it .
