Key features:

• Original nozzles for Flashforge Guider 2S 3D printer.
• This upgraded nozzle is more abrasion resistant for printing carbon fiber-filled or other abrasive filaments.
• The thermal conductivity of a hardened steel nozzle is not as good as a brass nozzle. Therefor you may need to increase your extruder temperature by 5-15°C. When printing abrasive filaments slow your first layer printing speed to 10mm/s.
