Strengths Comparison
TPE Strengths
TPU Strengths
- Perfect layer adhesion; extremely impact resistant; nearly indestructible
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
TPE Caveats
- Drive gears can squash it; hard to dial extrusion
- Print quality tends to be poor/runny
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
Frequently Asked Questions
Is TPE or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to TPE (Tier F). However, the best choice depends on your specific needs: TPE is best for various applications, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
