{name} in short
The default filament. Prints easily on almost any machine, holds detail well, and is cheap. It softens at low temperatures, so it is a poor choice for hot cars or functional outdoor parts.
{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.
