The Nylon PA6 Low Warp GF30 is a nylon filament reinforced with 30% glass fibres. This makes it a hard filament with high heat resistance (maximum 180˚C). In addition, the filament has excellent resistance to chemicals, is resistant to wear and shrinks little. Nylon PA6 Low Warp has good adhesion between layers and can be printed without a heated print chamber. This is a 1.75mm black filament on a 1kg spool.
