Fillamentum CPE vs ASA
Compare Fillamentum CPE and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Fillamentum CPE vs ASA: Fillamentum CPE is known for better chemical resistance than petg, while ASA is known for excellent uv resistance (outdoors indefinitely). Fillamentum CPE is easier to print; Fillamentum CPE prints at higher nozzle temperatures (275°C vs 220-275°C). Choose Fillamentum CPE for better chemical resistance than petg, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Fillamentum CPE
-Better chemical resistance than PETG; holds up to alcohols, water, acids, and bases
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface
Detailed Comparison
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
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
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
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
