Extrudr Flex Medium vs ASA
Compare Extrudr Flex Medium and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Extrudr Flex Medium vs ASA: Extrudr Flex Medium is known for excellent layer adhesion, while ASA is known for excellent uv resistance (outdoors indefinitely). Extrudr Flex Medium is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 240°C). Choose Extrudr Flex Medium for excellent layer adhesion, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Extrudr Flex Medium
-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
Extrudr Flex Medium 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
Extrudr Flex Medium 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
