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
Polycarbonate Strengths
- Very tough and stiff; doesn't shatter like PLA
- High heat resistance (~150C softening region)
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)
Considerations
Polycarbonate Caveats
- Often overkill and high effort for typical use
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 Polycarbonate or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to Polycarbonate (Tier B). However, the best choice depends on your specific needs: Polycarbonate is best for Very tough and stiff; doesn't shatter like PLA, while TPU is best for Excellent layer adhesion; extremely impact resistant; highly durable.
What are the temperature differences between Polycarbonate and TPU?
Polycarbonate prints at 260-310°C nozzle / 90-120°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do Polycarbonate and TPU need an enclosure?
Polycarbonate: required. TPU: not needed.
Which is more beginner-friendly: Polycarbonate or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
