Strengths Comparison
PCTG Strengths
- Tough, strong layer adhesion, minimal warping/sagging
- Lower moisture uptake vs PETG; very easy printing for performance level
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
PCTG Caveats
- Supports can be hard to remove
- Expensive and harder to find
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 PCTG or TPU better for 3D printing?
PCTG is generally rated higher (Tier S) compared to TPU (Tier S). However, the best choice depends on your specific needs: PCTG is best for Tough, strong layer adhesion, minimal warping/sagging, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between PCTG and TPU?
PCTG prints at 230-260°C nozzle / 70-85°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do PCTG and TPU need an enclosure?
PCTG: optional. TPU: not needed.
Which is more beginner-friendly: PCTG or TPU?
Both PCTG and TPU are beginner-friendly options.
