Polypropylene (PP)


Polypropylene (PP)

Polypropylene (PP) for Selective Laser Sintering. With this material, PP parts can be generated using the selective laser sintering technology.

Pre-series parts can thus be produced in the same basic material as large series parts. Decisive advantages of this material are the outstanding toughness and media resistance. In addition, Polypropylene (PP) is sterilizable (medical technology) and the sealability allows welding with other PP parts.
