{name} in short
ABS with far better UV and weather resistance. The go-to material for anything that lives outdoors. Same enclosure and ventilation requirements as ABS.
{name} in short
The best all-round functional filament for most people. Tough, slightly flexible, weather resistant, and food-contact friendly in most formulations. Tends to string and stick too well to smooth beds.
