Prusament PVB vs ASA
Compare Prusament PVB and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Prusament PVB vs ASA: Prusament PVB is known for alcohol smoothing (isopropanol) can fuse layers and create..., while ASA is known for excellent uv resistance (outdoors indefinitely). Prusament PVB is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 215°C). Choose Prusament PVB for alcohol smoothing (isopropanol) can fuse layers and create..., or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Prusament PVB
-Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
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
Prusament PVB Strengths
- Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
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
Prusament PVB Caveats
- Alcohol vapor can fuse the spool itself (example: spool stuck together)
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
