Super Print Upgrade I3 Mega All Metal Hotend Kit,Upgrade Bi-Metal Heatbreak,Heater Block Aluminum,V6 Brass Nozzle 0.4mm for Mega,Mega X,Mega S,Mega Pro,Chiron,V5 Head Hotend.

1、We choose the best materials that we can find on market combined with high precision CNC maching to bring this high quality brass nozzle (Tolerance 0.01 mm),Sleek Inner Wall.Smooth filament feed-out Less glitches Lower viscosity. Brass nozzles high cost performance, suitable for printing 1.75mm PLA ABS TPU PA and other conventional materials. 2、Upgrade bi-metal heatbreak: Heat insulation good,titanium alloy reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction,We use a special process to hold them firmly together. You don't need to worry about it being damaged.(Note: After installing the new hot end, please make sure to perform PID calibration before printing.) 3、The nozzle and heatbreak appearance is more shiny,thread precision improvement.The inner wall of the tube is smoother (reducing the chance of filament clogging).The interface is smoother and more precise (can effectively prevent the filament from leaking). 4、The i3 mega all metal hotend is equipped with an upgraded bi-metal heatbreak,providing excellent thermal insulation performance,effectively reduces heat loss and improves printing efficiency and reducing temperature fluctuations in the hotend. This results in a more stable and reliable hotend, reducing the occurrence of heat creep and improving print quality. 5、The heatsink and heater block from high-quality aluminum, It is not inferior or cheap aluminum.This guarantees the overall performance of the product, coupled with high-precision CNC machining and stringent quality assurance, delivering users a high-quality all metal hotend.
