Ultimaker PP: for functional prototypes and durable end use parts

Ultimaker PP Polypropylene filament is now available from Redstack. Polypropylene (PP) is one of the most commonly used plastics in the world. It's a favorite material of many manufacturers and engineers and is utilised across a wide range of applications. With its toughness and exceptional fatigue resistance, it is a great material for creating functional prototypes and durable end use parts. With a low density, polypropylene can be used to produce lightweight parts with a high strength to weight ratio. 

Polypropylene also delivers outstanding temperature, electrical, and chemical resistance. It can withstand temperatures up to 105°C, it can be used as an electrical insulator, and can tolerate a wide range of bases and acids - including industrial cleaning chemicals. Polypropylene is also semi flexible, translucent, and has low friction and smooth surfaces, making it suitable for producing everything from electrical components to working hinges.  With a high fatigue resistance, it does not break when repeatedly bent, allowing it to be used for a broad range of applications such as clamps and hinges.    

Why choose Ultimaker PP?
Polypropylene is popular worldwide with engineers and manufacturers for a wide variety of applications.

  • Durable with high toughness and fatigue resistance (PP retains its shape after torsion, bending, and/or flexing)
  • Low friction and smooth surfaces
  • Good heat resistance (up to 105°C)
  • Semi-flexible
  • Chemical resistance to a wide range of bases and acids, including industrial cleaning agents
  • High electrical resistance makes it a good electrical insulator
  • Very resistant to moisture
  • Translucent
  • Low density resulting in lightweight parts (high strength-to-weight ratio)
  • Excellent layer bonding
  • Adequate bed adhesion and low warping when using Advanced 3D Printing Kit stickers
  • Recyclable, for low environmental impact

See examples below of a bottle and clamp, both printed with Ultimaker PP filament:

Ultimaker PP Examples

Ultimaker PP is a good choice for printing low friction end use parts that have good fatigue resistance and toughness. When printing using one of the extensively tested Cura profiles for Ultimaker 2+ or Ultimaker 3 3D printers, you get reliable results and a seamless 3D printing experience.
