Direct Metal Laser Sintering is a metal additive manufacturing technology in which a high power laser focus sinters metal powder layer by layer according to the coordinates specified in a CAD file.
Selective Laser Sintering technology is a plastic additive manufacturing technology in which a laser that melts the plastic powder particles according to the specified 3D model is used as a thermal energy source and repeats the process layer after layer.
Stereolithography or Photopolymerization is a plastic additive manufacturing technology that consists of hardening or polymerizing a liquid photopolymer through an ultraviolet laser focus, selectively layer by layer.
Photopolymer Injection is a plastic additive manufacturing technology in which a print head travels by injecting a plastic material reactive to ultraviolet light (photopolymer) and a UV lamp hardens it after being injected. The process is repeated layer by layer.
