Selective Laser Sintering (SLS) is an additive manufacturing technique that makes use of a melting laser beam to fabricate solid 3D objects.
The process has been developed in 1980 by Carl Deckard, a student at the Texas university, together with his professor Joe Beaman.
He co-founded Desktop Manufacturing Corp. (DTM) but later sold his business to 3D Systems Inc. a company that developed the stereolithography (SLA), a technique similar to SLS.
The main difference between both methods is that SLS uses powder instead of liquid photopolymer resin.
Unlike other additive production processes such as stereolithography or FDM (Fused Deposition Modelling), SLS does not need any support structure.
Like all other additive manufacturing technologies, Selective Laser Sintering starts with the creation of a CAD file, to be converted to .STL format.
Thanks to the great variety of different materials such as nylon, ceramics, aluminium, steel or silver that could be used, the SLS system is very popular and widespread in the 3D world.
The parts created through Selective Laser Sintering can be made out of high performance materials such as Prototech,(aluminium filled nylon), Protoplus (standard polyamide) and Protoglass (glass-filled nylon) .
The SLS technology is ideal for the fabrication of small production batches and prototypes of large dimensions, whose parts are assembled and finished in our post-production department.
The Selective Laser Sintering allows to produce both functional and aesthetic prototypes with the desired surface finishing.
