In selective laser sintering (LS), fine thermoplastic powder is melted layer by layer using a CO² laser to produce complex three-dimensional components with high mechanical properties. PA12 has become the dominant material for this process. Alternative thermoplastics are rarely available in sufficient quantities. Powder flowability and the resulting component properties in the LS process depend primarily on the particle shape. For this reason, a high degree of sphericity of the individual powder particles is beneficial. Conventional powder production processes are particularly inadequate for ductile and tough materials. For this reason, we offer the materials polypropylene (PP) and urethane-based thermoplastic elastomers (TPU) as powders for the LS sector with highly spherical particles.

Areas of application
Selective laser sintering (LS) of plastics requires extremely fine powder with spherical particles and the highest possible packing density. For this reason, we offer these optimized PP and TPU powders for the LS process.
The components manufactured in this way are used both as prototypes and as directly usable components, design and advertising elements, orthopedic and patient-adapted insoles and, for example, as cost-effective spare parts.
