SLS, or Selective Laser Sintering, is a 3D printing technique that builds objects layer by layer by melting thermoplastic powder. A fine layer of powder is evenly distributed across the building surface, and a laser fuses the plas…

SLA, short for stereolithography, is a 3D printing process where an UV laser creates layer after layer by selectively curing and solidifying a photopolymer resin.
