ColorFabb nGen flex vs ASA
Compare ColorFabb nGen flex and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
ColorFabb nGen flex vs ASA: ColorFabb nGen flex is known for excellent layer adhesion, while ASA is known for excellent uv resistance (outdoors indefinitely). ColorFabb nGen flex is easier to print; ColorFabb nGen flex prints at higher nozzle temperatures (260°C vs 220-275°C). Choose ColorFabb nGen flex for excellent layer adhesion, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
ColorFabb nGen flex
-Excellent layer adhesion; extremely impact resistant; highly durable
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
ColorFabb nGen flex Strengths
- Excellent layer adhesion; extremely impact resistant; highly durable
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
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
ColorFabb nGen flex Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
