Selective Laser Sintering, SLS
A laser sintering machine will coat a layer of plastic powder onto a build platform, which is melted by a laser (or multiple lasers). The build platform will then be lowered and the next layer of plastic powder will be laid out on top. By repeating the process of laying out powder and melting where needed, the parts are built up in the powder bed.
Laser Sintering does not require any support structures. The built parts are sustained by the loose plastic powder. The entire build volume can therefore be filled with several parts including stacking and pyramiding of parts, which are then all produced together. The process chamber is preheated and under a protective gas environment.
The technology manufactures parts in standard plastics with good mechanical properties. A constantly widening set of materials is available. For small lot sizes, laser sintering is price competitive and often the cheapest solution.
Laser sintering parts do not have exactly the same properties as their injection molded counterparts. Especially in regards to surface finish.
