Laser sintering

As an alternative to injection molding, laser sintering is a proven manufacturing process for prototypes and small series.

Layer by layer material is being additively built up to an individual component.

Prior to production, a 3D model 1 of a new component is generated on computer. The computer 2 controls the laser sintering process in the build chamber, where the component emerges layer by layer. A roller 3 pushes a thermoplastic polyurethane (TPU) powder into the building chamber. The laser beam 4 scans the single TPU layer, fusing the TPU powder into a solid layer. A close-up 5 of the component shows how the TPU powder melts through the contact with the laser beam, and re-solidifies afterwards.

Desmopan® is not directly supplied in powder form for this technique, but delivered in the form of granules to our partner Lehmann & Voss & Co.
Lehmann & Voss & Co. then produces a cold-milled powder which they sell under the trade name Desmosint®.
