PC (Polycarbonate) vs TPU
Compare PC (Polycarbonate) and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
PC (Polycarbonate) vs TPU: PC (Polycarbonate) is known for extremely stiff, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; PC (Polycarbonate) is less moisture-sensitive; PC (Polycarbonate) prints at higher nozzle temperatures (270-275°C vs 200-240°C). Choose PC (Polycarbonate) for extremely stiff, or TPU for excellent layer adhesion.
Key differences at a glance
PC (Polycarbonate)
-Extremely stiff; useful where flex must be minimal
TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable
Detailed Comparison
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
PC (Polycarbonate) Strengths
- Extremely stiff; useful where flex must be minimal
- Surprisingly affordable in some brands
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
PC (Polycarbonate) Caveats
- Feeding can be difficult unless spool is close/direct-fed
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
