Ultimaker CPE (co-polyester) material is an ideal choice for 3D printing functional prototypes and mechanical parts. This filament is formulated for chemical resistance, toughness, and reliable dimensional stability.

CPE Ultimaker


Ultimaker CPE material is developed for a seamless experience with Ultimaker hardware.

  • Excellent chemical resistance
  • High toughness and dimensional stability
  • High impact strength
  • A range of colors to choose from, including grayscale for professional-looking models


Below are a few of Ultimaker CPE’s key mechanical properties:

  • Good flexural strength (Flexural modulus of 2100 MPa)
  • Good tensile strength (Tensile stress at break 38 MPa)
  • High impact strength (Izod tested to 95 J/m)
  • High hardness (Rockwell 108)


Similar to PET and PETG, Ultimaker CPE is ideal for a range of applications:

  • Visual and functional prototyping
  • Short-run manufacturing
  • Custom components
  • Fit testing
  • Tooling


Ultimaker CPE material is officially supported by the Ultimaker S5, Ultimaker 3 series, and Ultimaker 2+ series of 3D printers. It is compatible for dual extrusion with:

  • Ultimaker Breakaway
  • Ultimaker PVA
