TPU vs ABS
How TPU and ABS compare, from typical settings across every filament we list.
- TPU is easier to print, tougher, better outdoors and more flexible; ABS is stiffer and more heat resistant.
- ABS typically prints about 20 °C hotter at the nozzle.
- ABS typically prints about 55 °C hotter on the bed.
- ABS is less dense, so a 1 kg spool holds about 56 m more 1.75 mm filament.
- There are 158 TPU filaments in 945 colours, and 151 ABS filaments in 1,021 colours.
