Print Temperature: 180-220°C
PETG (Polyethylene Terephthalate Glycol)
Strong and durable with good temperature resistance
Properties
- Strong and durable
- Water resistant
- Good layer adhesion
- More challenging than PLA
Best For
- Functional parts
- Outdoor use
- Mechanical parts
Print Temperature: 230-250°C
ABS (Acrylonitrile Butadiene Styrene)
Tough and heat-resistant, but requires ventilation
Properties
- High strength
- Heat resistant
- Requires heated bed
- Needs good ventilation
Best For
