selective laser sintering (SLS)

Selective Laser Sintering (SLS) is a 3D printing technique for rapid prototyping

. In selective laser sintering, which is based on the sintering of printing powder, the printing powder is applied layer by layer in thin layers and fused together in a sintering process. In selective laser sintering, the melting temperature is generated by a powerful carbon dioxide laser. Polyamide, ceramic or metal powder is used as the printing powder. The layer thickness is between 1 µm 0.2 mm, the layers are sintered or melted down. The resolution

is very high and is between 1 µm and 200 µm.

3D printing techniques

The production of 3D models using the LSL process is extremely time-consuming and can take several hours. This is due to the fact that the printing material has to cool down after sintering before a new layer of printing powder is printed. Therefore, laser sintering is primarily suitable for prototype production.
