{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
Flexible, rubber-like filament. Prints slowly and needs a direct-drive extruder or a well-tuned Bowden setup. Great for phone cases, gaskets, and wearables.
