Fillamentum CPE vs TPU

Compare Fillamentum CPE and TPU filaments side-by-side so you can pick the right one for your 3D printing project.

Fillamentum CPE vs TPU: Fillamentum CPE is known for better chemical resistance than petg, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Fillamentum CPE is less moisture-sensitive; Fillamentum CPE prints at higher nozzle temperatures (275°C vs 200-240°C). Choose Fillamentum CPE for better chemical resistance than petg, or TPU for excellent layer adhesion.

Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.

Strengths Comparison

Fillamentum CPE Strengths

  • Better chemical resistance than PETG; holds up to alcohols, water, acids, and bases
  • Tough and ductile with strong impact resistance; bends where PLA would snap
  • Heat resistant to roughly 75°C plus UV resistance, so it survives outdoors
  • Low moisture uptake and minimal shrink/warp for an engineering material
  • Strong layer adhesion suits thin-walled models and parts under mechanical stress

TPU Strengths

  • Excellent layer adhesion; extremely impact resistant; highly durable
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

Considerations

Fillamentum CPE Caveats

  • Bonds hard to the build plate; the wrong sheet can be damaged on part removal
  • Around 275°C at the nozzle rules out PTFE-lined hotends
  • Less widely stocked and pricier than PETG for a modest step up in performance

TPU Caveats

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly

Frequently Asked Questions

What is the difference between Fillamentum CPE and TPU?
Fillamentum CPE prints at 275°C nozzle / 90°C bed (No enclosure, low moisture sensitivity). TPU prints at 200-240°C nozzle / 30-60°C bed (No enclosure, high moisture sensitivity).
Is Fillamentum CPE or TPU stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Fillamentum CPE is suited to better chemical resistance than petg, while TPU is suited to excellent layer adhesion.
Which prints at a higher temperature, Fillamentum CPE or TPU?
Fillamentum CPE prints at a higher temperature (275°C nozzle vs 200-240°C for TPU).
Is Fillamentum CPE or TPU better for beginners?
Fillamentum CPE is better for beginners: enclosure is no and moisture sensitivity is low, vs no enclosure and high moisture for TPU.
Should I use Fillamentum CPE or TPU for flexible parts?
For flexible parts, TPU is usually the better fit (Excellent layer adhesion). Choose Fillamentum CPE instead when better chemical resistance than petg.
