Strengths Comparison
PVA / BVOH Strengths
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
PVA / BVOH Caveats
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
