3D Printing polypropylene (PP)

Polypropylene is one of the most common plastics overall. Packing products like clear tape, ready meal boxes etc.. are made from polypropylene. PP has excellent chemical resistance and endures higher temperatures than other foodsafe plastics. A huge con of PP is the printing, as it requires a special plate also made from PP, otherwise it will deform away from the print surface.

Pros

  • Chemical resistance
  • Temperature resistance
  • Semi flexible
