ABS vs TPU
Compare ABS and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
ABS
CAcrylonitrile Butadiene Styrene
Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable

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
ABS Strengths
- Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
- Good impact toughness for the price
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
ABS Caveats
- Warps heavily
- Strong fumes/off-gassing; enclosure plus ventilation recommended
- Poor UV resistance; yellows and gets brittle outdoors (ASA is the better outdoor/UV choice)
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 ABS or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to ABS (Tier C). However, the best choice depends on your specific needs: ABS is best for Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance, while TPU is best for Excellent layer adhesion; extremely impact resistant; highly durable.
What are the temperature differences between ABS and TPU?
ABS prints at 230-255°C nozzle / 95-110°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do ABS and TPU need an enclosure?
ABS: recommended. TPU: not needed.
Which is more beginner-friendly: ABS or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
