PolyLite is a family of 3D printing filaments made from the finest raw materials to deliver exceptional quality and reliability. PolyLite covers the most popular 3D printing materials to meet your daily design and prototyping needs. PolyLite PLA is a high-quality PLA designed for reliability and easy printability. PolyLite PLA is based on a high molecular weight PLA from Natureworks, making it one of the stiffest PLA materials on the market. Polymaker Jam-free technology increases the heat resistance of the filament itself (not the printed part) to 140°C. This prevents an interference problem due to the problem with heat crawling at the hot end. Heat crawling is the process by which the heat spreads irregularly in your hot end, softens the filament before entering the melting chamber, and blocking the filament by expanding in the cold end. Increasing the heat resistance of the filament from 60°C to 140°C ensures a jam-free experience.
