Ultrafuse ABS vs TPU
Compare Ultrafuse ABS and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Ultrafuse ABS vs TPU: Ultrafuse ABS is known for fast printing, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Ultrafuse ABS is less moisture-sensitive; Ultrafuse ABS prints at higher nozzle temperatures (255°C vs 200-240°C). Choose Ultrafuse ABS for fast printing, or TPU for excellent layer adhesion.
Key differences at a glance
Ultrafuse ABS
-Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
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
Ultrafuse 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
Ultrafuse 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
