Selective Laser Sintering – SLS

With components made using the laser sintering process, both functional samples and small series can be produced in a very short time. Laser sintering is characterised by attention to detail and excellent material properties. In the time-to-market principle, risks can be minimised in product development and thus series start-ups can be significantly shortened.

Due to the layered construction and the lack of support geometries, laser sintering has almost unlimited possibilities in terms of design and construction. Complex and filigree components as well as compact structures can be created. Different materials also allow the use for series applications. SLS technology has been used successfully for years in a wide range of applications, especially in the automotive and aerospace industries. In laser sintering, a plastic powder is applied layer by layer and the component geometry is partially fused by a laser. Layer thicknesses of 120 to 80 µm can be achieved. In contrast to many other additive processes, no support geometries are necessary in laser sintering. This means that any number of components can be produced in a single job. It is also possible to produce entire assemblies without the otherwise necessary subsequent assembly.
