PEKK vs ASA
Compare PEKK and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
PEKK vs ASA: PEKK is known for nearly peek-class strength with far better print success..., while ASA is known for excellent uv resistance (outdoors indefinitely). ASA is easier to print; PEKK prints at higher nozzle temperatures (340-380°C vs 220-275°C). Choose PEKK for nearly peek-class strength with far better print success..., or ASA for excellent uv resistance (outdoors indefinitely).

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
PEKK Strengths
- Nearly PEEK-class strength with far better print success rate
- Described as one of the easiest high-end polymers to print once equipment checks pass
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
PEKK Caveats
- Extremely expensive and very difficult to print; warping/curling issues (pricing varies widely by brand, so verify current pricing)
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
