Selective Laser Sintering (SLS^®) is an additive fabrication method used to produce durable and functional models and prototypes.  As an additive technology, SLS can produce parts with highly complex geometries.

The SLS process is mainly comprised of a CO₂ laser and a thermoplastic (nylon) or metal powder.  Based on CAD data, computer software directs the laser to sinter particles of powdered material together one layer at a time.

As SLS technology develops and matures, it is increasingly being adopted as a method for producing end use parts.  In many cases, the final SLS part can exhibit material properties comparable to those achieved through traditional manufacturing methods.

Highlights of the SLS process include:

• Functional parts (living hinge, etc)
• No support structures needed
• Complex geometries
• Speed (delivery in 2-3 days)
