Selective Laser Sintering (SLS) for Additive Manufacturing

Selective Laser Sintering (SLS) for Additive Manufacturing

Selective laser sintering is an additive process that draws on a bed of thermoplastic powder to create a fully sintered, Nylon-based part. This technique is ideal for parts with highly complex geometries.

The SLS process involves a CO2 laser drawing onto a hot bed of thermoplastic powder. From there, it lightly sinters, or fuses, the powder into a solid. After a layer is sintered, a roller places another layer of thermoplastic powder on top of the bed to repeat the process. This results in parts and/or prototypes that are highly durable and accurate, but have a rougher surface and lack finer details than you’d see in stereolithography techniques.
