This guide is taken from Bambu Labs filament guide comparison. We omited the other materials as we are offering these 3 filament materials only.
PLA Thermoplastic
- Biodegradable
- Recyclable
- High glass transition temperatures
- Good form stability
- Good visual transparency
ABS Thermoplastic
- High rigidity, good weldability, and insulating properties
- Good impact resistance
- Good abrasion and strain resistance
- High dimensional stability
- High surface brightness
PETG
We found a simple comparison guide for filament type which can help you decide which is best for your applications. Main difference here is with ABS, however most prints with PETG or PLA will suffice.
