This hot end with hardened steel nozzle is ideal for printing with filaments that have added particles, such as glass or carbon fibres. In addition, the printing time is reduced because the diameter is larger than the standard 0.4mm nozzle. This makes this size a good choice for 3D printing larger parts, functional parts, industrial parts and 3D models that need to be strong. The nozzle is 0.4mm and is suitable for the A1 series 3D printers from Bambu Lab.
