Strengths Comparison
TPE 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
TPE Caveats
- Drive gears can squash it; hard to dial extrusion
- Print quality tends to be poor/runny
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is TPE or ASA better for 3D printing?
ASA is generally rated higher (Tier A) compared to TPE (Tier F). However, the best choice depends on your specific needs: TPE is best for various applications, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between TPE and ASA?
TPE prints at 200-230°C nozzle / 30-50°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do TPE and ASA need an enclosure?
TPE: not needed. ASA: recommended.
Which is more beginner-friendly: TPE or ASA?
TPE is more beginner-friendly as it doesn't require an enclosure.
