{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.
{name} in short
Extremely strong, tough, and wear resistant. It is also very hygroscopic: it must be dried and printed from a dry box, or it will print foamy and weak.
