ABS vs TPU
Compare ABS and TPU filaments side-by-side. See which one is best for your 3D printing project.
ABS
CAcrylonitrile Butadiene Styrene
Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
TPU
SThermoplastic Polyurethane
Perfect layer adhesion; extremely impact resistant; nearly indestructible

Strengths Comparison
ABS Strengths
- Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
- Outdoor capable for years (not fully UV proof but long-lasting)
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
ABS Caveats
- Warps heavily
- Strong fumes/off-gassing; enclosure recommended
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 Perfect layer adhesion; extremely impact resistant; nearly indestructible.
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.
