Super Print Sprite Extruder/Pro Heater Block Upgrade Hotend Kit,Ender 3 S1 Bi Metal Heatbreak,Brass Nozzle 0.4mm for Ender S1,Ender Pro,S1 Plus,CR10 Smart Pro,Sermoon V1,300℃

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. 3、The Brass 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 Ender 3 S1 Hotend is equipped with an upgraded Bi-Metal Heatbreak and Titanium Alloy Screws, providing excellent thermal insulation performance. It minimizes heat loss to the maximum extent, enhancing 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 NTC100K B3950 thermistor size of 3 x 5.5mm,Total length about 52mm, 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.)
