Strengths Comparison
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)
TPE Strengths
Considerations
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
TPE Caveats
- Drive gears can squash it; hard to dial extrusion
- Print quality tends to be poor/runny
Frequently Asked Questions
Is TPU or TPE 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: TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible, while TPE is best for various applications.
What are the temperature differences between TPU and TPE?
TPU prints at 200-240°C nozzle / 30-60°C bed. TPE prints at 200-230°C nozzle / 30-50°C bed.
Do TPU and TPE need an enclosure?
TPU: not needed. TPE: not needed.
Which is more beginner-friendly: TPU or TPE?
Both TPU and TPE are beginner-friendly options.
