PEI vs HIPS
How PEI and HIPS compare, from typical settings across every filament we list.
- PEI is tougher, stiffer, more heat resistant and better outdoors; HIPS is easier to print.
- PEI typically prints about 125 °C hotter at the nozzle.
- PEI typically prints about 40 °C hotter on the bed.
- HIPS is less dense, so a 1 kg spool holds about 73 m more 1.75 mm filament.
- There are 17 PEI filaments in 24 colours, and 15 HIPS filaments in 46 colours.
