  • PP-based & HDPE-based powders for 3D Printing
  • Further improved mechanical values, elongation at fracture now at 7.5%
  • For layer thicknesses down to 100µm, parts as thin as 1.5mm
  • Parts can be painted & welded

Diamond Plastics GmbH, Nuremberg, Germany, has introduced a new polypropylene powder grade for SLS (Selective Laser Sintering). The Laser PP CP 75 grade features improved mechanical values. For example, the elongation at fracture has been increased from previously 2.2% (PP CP 22) to 7.5%.

The material, based on polypropylene can be processed on all state of the art laser sinter equipment. Parts manufactured from this material are dimensionally stable and feature very good chemical resistance. With a maximum particle size of 90µm, the powder can be processed at a layer thickness of 100µm.

The company also offers the HDPE-based laser sintering powder HDPE HX 17 which can also be processed on all state of the art laser sinter equipment and is also 100% reusable. The HDPE material features high rigidity and is suitable for parts as thin as 1,5mm. The smooth surface makes Laser HDPE HX 17 very suitable for the production of master forms for vacuum casting. The powder, dark grey in colour, can be processed at a layer thickness of 100µm. Finished parts can be painted, welded or crosslinked. As it is based on HDPE, the material is resistant against acid and base, alcohol, oil and gasoline.
