Add North’s Rigid X is a carbon fiber reinforced PETG filament. It combines the excellent chemical, heat and UV-resistance of regular PETG, along with the strength and stiffness of carbon fibers. It also adds about 10-20°C in heat resistance, making it the perfect material for a broad range of demanding applications, such as vehicle parts, fixtures or jiggs.

Rigid X is effortless to print. You can easily achieve maximum layer adhesion and a beautiful surface finish, with zero warping. Because of the higher print temperatures, starting at 245 °C, we recommend an all metal hotend. Rigid X is a highly abrasive filament that requires a hardened steel nozzle or equivalent. Nozzle X works very well for printing all our abrasive filaments.

Rigid X is available in black and a green camo color.

Rigid X is available in 500g and 1,000g spool sizes in 1.75mm and 2.85mm diameter.
