Direct Metal Laser Sintering (DMLS) uses a laser as the power source to sinter the powdered metal material, aiming the laser automatically at points in space defined by a 3D model, sintering the metal particles together to create a solid structur

Selective laser sintering (SLS) uses a laser as the power source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

Stereolithography (SLA) uses a laser to solidify a layer of liquid resin onto a build platform, which moves up out of the resin tank and the process is repeated, building the part layer by layer.
