Heating block & throat Material upgrade: Upgrading the heating block with chrome zirconium copper nickel platingtreatment for fast thermal conductivity and high temperature resistance for printing, The titanium alloy throat is wrapped with chromium zirconium copper for better heat dissipation.The throat and heating block are integrated into a formed structure: The throat structure has been upgraded, and a step limit has been added at the joint with the heating block, Solve the phenomenon of material leakage and detachment.Heating block, nozzle High temperature and wear resistance upgrade: The heating block has been upgraded to chrome zirconium plated copper and nickel plated treatment, which can withstand high temperatureprinting at 550 C and has fast thermal conductivity. The nozzle is made of hardened steel SKD11, which has undergone quenching hardening treatment and nano treatment. It can be heated up to 550 C or above, making it more wear- and extending its service life.Upgrade of nozzle structure: The heating block and nozzle are connected by threads, utilizing the contact between the nozzle and at the bottom of the throat to firmly solve the problem of detachment and reduce the possibility of material leakage. The detachable nozzle reduces the cost of use.Inner wall of throat and nozzle Roughness Ra 0.4:The inner walls of the throat and nozzle are smooth, reducing blockage and improving printing quality.Upgrade Your 3D Printer: Introducing the V2.0 upgraded hotend for models .This advanced print features a bi-metal heatbreak designed for superior durability and performance.Enhanced Durability: Engineered with a robust bi-metal heatbreak, this hotend resists bending under stress, ensuring consistent performance and . 2.0 extrusion : Efficient heating I High temperature printing, High performanceSmall size & light weight: Aluminum radiator, integrated throat heating block, replaceable threaded hardened steel nozzle.Titanium alloy screw fixation: The heating block is connected to the radiator through two titanium alloy screws, Avoid bending and breaking of the throat during high-speed printingTop thread fixed aluminum radiator: The radiator and throat are fixed by top screws and connected stably, Removable and replaceable, reducing usage costs.Colour:As ShownMaterial:Metalstyle:P1Package Contents:1 * For Hotend KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
