- Filament
- PLA FilamentsPLA is a biodegradable, renewable plastic that is easy to print and affordable.
- PETG FilamentsPETG is an alternative to ABS for those who do not have an enclosure to print in. PETG filaments have excellent layer adhesion and handle heat up to 70-80C for higher ambient temperatures.
- ABS FilamentsABS is a very strong plastic with high-temperature resistance (100C+). ABS should be printed inside an enclosure to ensure part strength and reduce warping.
- Nylon FilamentsNylon is a very STRONG filament where durability and layer adhesion is needed. These filaments are typically able to be printed without an enclosure and need a high nozzle temp of 230-250C and bed temp up to 80C. These are more expensive than PLA or ABS but their strength is unmatched.
- Recycled FilamentsRecycled filaments are made from recycled materials. If you’re eco-conscious these are worth checking out!
