Feature:1. [Upgrade Hotend Kit] This hotend kit is compatible with for Bambu Lab X1 X1 C P1P P1S models, and can also be paired with other DIY designs for seamless integration.2. [High Temperature Resistant] CR Zr copper ni electroplated heating block, capable of withstanding temperatures up to 500, offering efficient thermal conductivity.3. [All Metal Throat] The kit features an all metal smoothly insulated throat made of dual metal copper titanium alloy, improving heat dissipation, enhancing overall performance.4. [Smoothly Printing] With a throat and nozzle inner wall roughness of Ra0.4, this kit minimizes clogging issues and enhances printing precise, resulting in superior print quality.5. [Stable Connection] Anodized black heatsink and titanium alloy bi metal insulated throat tube are fixed with M3 top wire, stable in connection, detachable for replacement.6. [Upgrade Throat Structure] Upgraded throat structure with added step limit at the junction with the heating block to reduce leakage and detachment.7. [Titanium Alloy Screw Fixation] Upgraded connection of heating block and heatsink with two titanium alloy screws to prevent throat bending and breaking during high speed printing. Titanium alloy provides better heat insulation, increased stability.Specification:Item Type: 3D Printer Hotend KitMaterial: CR Zr Copper Ni, Aluminum Alloy, Copper Titanium Alloy, Silicone, Hardened Steel, BrassExtruder Nozzle Specification: 1.75mm 0.4mmHardened Steel Nozzle Specification: 1.75mm 0.4mm x 1, 1.75mm 0.6mm x 1Brass Nozzle Specification: 1.75mm 0.4mm x 1, 1.75mm 0.6mm x 1Maximum Extruder Temperature: 500.Package List:1 x Hotend 1.75mm 0.4mm1 x Hotend Clamp1 x Accessory1 x Open End Wrench1 x Hex Wrench1 x Thermal Conductive Grease1 x Silicone Insulation Sleeve2 x Screws2 x Limiter1 x Thermistor Wire1 x Heating Sheet2 x Brass Nozzles (1.75mm 0.4mm x 1, 1.75mm 0.6mm x 1)2 x Hardened Steel Nozzles (1.75mm 0.4mm x 1, 1.75mm 0.6mm x 1)
