ASA vs PP
How ASA and PP compare, from typical settings across every filament we list.
- ASA is stiffer, more heat resistant and better outdoors; PP is more flexible.
- ASA typically prints about 25 °C hotter at the nozzle.
- ASA typically prints about 10 °C hotter on the bed.
- PP is less dense, so a 1 kg spool holds about 73 m more 1.75 mm filament.
- There are 109 ASA filaments in 638 colours, and 28 PP filaments in 50 colours.
