PVA / BVOH vs ASA

Compare PVA / BVOH and ASA filaments side-by-side so you can pick the right one for your 3D printing project.

PVA / BVOH vs ASA: PVA / BVOH is known for general use, while ASA is known for excellent uv resistance (outdoors indefinitely). PVA / BVOH is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 195-215°C). Choose PVA / BVOH for general use, or ASA for excellent uv resistance (outdoors indefinitely).

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

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)

    PVA / BVOH Caveats

      ASA Caveats

      • Still off-gasses; enclosure/ventilation recommended
      • Can still warp; needs tuning

      Frequently Asked Questions

      What is the difference between PVA / BVOH and ASA?
      PVA / BVOH prints at 195-215°C nozzle / 60°C bed (No enclosure, low moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
      Is PVA / BVOH or ASA stronger?
      Our dataset does not include comparable tensile strength values for both. Qualitatively, PVA / BVOH is suited to , while ASA is suited to excellent uv resistance (outdoors indefinitely).
      Which prints at a higher temperature, PVA / BVOH or ASA?
      ASA prints at a higher temperature (220-275°C nozzle vs 195-215°C for PVA / BVOH).
      Is PVA / BVOH or ASA better for beginners?
      PVA / BVOH is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
      Should I use PVA / BVOH or ASA for outdoor use?
      For outdoor use, ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose PVA / BVOH instead when .
