SLS

Selective Laser Sintering is similar to SLA except a powder is cured instead of a resin. The advantage of SLS is that much tougher materials can be used such as glass filled nylon. The resolution of SLS printers is not as good as SLA so the surface finish is no where near as smooth as SLA but as you can used tougher materials it is great for fit and function testing and also for rapid manufacturing for non visible parts.

The parts are built by melting powder plastic with a CO2 Laser which traces around the profile of the part for each slice.
