Super Print Upgrade Prusa i3 MK2 Hotend 12V 40W Kit,Upgrade V6 Bi Metal Heatbreak,Heater Block Aluminum,V6 Brass Nozzle 0.4mm for MK2,MK2S,MK2.5,MK2.5S 3D Printer Kit.

1、(Note: You need to install this hot end yourself)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. 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 Prusa i3 MK2 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、Optimized thermistor: Features an ATC Semitec 104GT-2 thermistor, eliminating the need for firmware changes on your Prusa 3D, made of high quality materials, ensuring superior stability, durability, and more accurate temperature measurement. Avoid problems during printing, provide users with a better printing experience.(The sensor is capable of measuring higher temperatures, Reaching up to 300°C.)
