In the selective laser sintering of plastics (LS), fine thermoplastic plastic powder is fused layer by layer using a CO² laser, thus producing complex three-dimensional components with high mechanical properties. The material PA12 has established itself as the dominant material for this process. Alternative thermoplastics are rarely available in sufficient form. In the LS process, the powder flowability and the resulting component properties depend in particular on the particle shape. For this reason, a high sphericity of the individual powder particles is beneficial. Conventional powder production processes are inadequate, particularly for ductile and tough materials. For this reason, we offer the materials polypropylene (PP) and thermoplastic elastomers based on urethane (TPU) as powders for the LS range with highly spherical particles.

application areas
For the selective laser sintering (LS) of plastics, extremely fine powder is required, with powder particles that are as spherical as possible and a packing density that is as high as possible. For this reason we offer these optimized powders made of PP and TPU for the LS process.
The components manufactured in this way are used both as prototypes and as technically directly applicable components, design and advertising elements, orthopedic and patient-adapted insoles and e.g. B. as inexpensive spare parts their application.
