PC-PBT vs TPU
Compare PC-PBT and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
PC-PBT vs TPU: PC-PBT is known for very easy pc-class filament (~260c), while TPU is known for excellent layer adhesion. TPU is easier to print; PC-PBT is less moisture-sensitive; PC-PBT prints at higher nozzle temperatures (250-270°C vs 200-240°C). Choose PC-PBT for very easy pc-class filament (~260c), or TPU for excellent layer adhesion.
Key differences at a glance
PC-PBT
APolycarbonate + PBT alloy
Very easy PC-class filament (~260C), low warping, good surface quality
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-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
- 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-PBT 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
