SLS (Selective Laser Sintering) is a powder-based fusion technique that uses a laser beam to sinter polymer powder, layer by layer, to create parts. A recoating blade puts an extremely thin layer of powdered material (0.1 mm) onto the build platform after it is heated at high temperatures in the overflow bin. After that, the building platform scans a whole cross-section, lowering the platform by one layer thickness. The unsintered powder will stay in the same place to support subsequent layers, eliminating the requirement for support structures. The recoating blade applies another layer of powder on top of the previously scanned layer. The laser beam then sinters the cross-section part onto the previously solidified cross-section. This process is repeated until the part is finished. 

SLS is required for users seeking a solution for manufacturing functional goods with complex geometries. This technology has little to no restrictions compared to other 3D printing technologies.

Materials

Polyamide 12 (PA 12)

Post Processing for SLS 3D Printing

Several post-processing techniques such as spray painting and dyeing can be done to improve the overall appearance of the 3D printed part.
