Polymaker Jam-Free™ Technology increases the heat resistance of the filament itself (not the printed part) to 140°C.
This prevent any jamming issue due to the hot end heat creep issue.
Heat creep is the process of heat spreading irregularly throughout your hot end, softening the filament before entering the melting chamber and jamming the filament by making it expand in the cold end..
The increase of the filament heat resistance from 60°C to 140°C ensures a Jam-Free experience.
(Note the printed part will have the same heat resistance as regular PLA: ~60°C)
