Strengths Comparison
PC-PBT Strengths
- Very easy PC-class filament (~260C), low warping, good surface quality
- Maintains shatter resistance and stays durable in cold (won't get brittle)
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
PC-PBT Caveats
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 PC-PBT or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to PC-PBT (Tier A). However, the best choice depends on your specific needs: PC-PBT is best for Very easy PC-class filament (~260C), low warping, good surface quality, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between PC-PBT and TPU?
PC-PBT prints at 250-270°C nozzle / 80-100°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do PC-PBT and TPU need an enclosure?
PC-PBT: recommended. TPU: not needed.
Which is more beginner-friendly: PC-PBT or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
