Features: Upgraded Hotend Kit with two hardened steel nozzles (0.2mm/0.4mm) enables high temperatures printing up to 500°C for carbon fiber composites and engineering plastics for qidi/PLUS 3 3D printers. modulars magnetic quick release design allows 5 second nozzle swaps and compatibility with auto leveling systems, featuring two fan for 20℃ temperatures reduction during extended printing. Essential for professional and engineering workshops requiring industrial to handle abrasive materials like carbon fiber nylons in precisions prototyping applications. Optimized for fast speed 3D printing demanding ±0.02mm layer accuracy, particularly when switching between composite materials and standard filaments during multiple materials projects. Pre installed thermals silicone and not tool nozzle replacement systems installation while hardened steel construction delivers 2000 hour durability for qidi/PLUS 3 extruder rail systems.
