Ultrafuse PRO1 vs ASA
Compare Ultrafuse PRO1 and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Ultrafuse PRO1 vs ASA: Ultrafuse PRO1 is known for easiest to print, while ASA is known for excellent uv resistance (outdoors indefinitely). Ultrafuse PRO1 is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 215°C). Choose Ultrafuse PRO1 for easiest to print, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Ultrafuse PRO1
-Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
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
Ultrafuse PRO1 Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
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
Ultrafuse PRO1 Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
