SainSmart TPU vs ASA
Compare SainSmart TPU and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
SainSmart TPU vs ASA: SainSmart TPU is known for excellent layer adhesion, while ASA is known for excellent uv resistance (outdoors indefinitely). SainSmart TPU is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 230°C). Choose SainSmart TPU for excellent layer adhesion, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
SainSmart TPU
-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
SainSmart TPU 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
SainSmart TPU 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
