1、Detachable Nozzle Design: The end nozzle is detachable and secured with M5 threading, featuring internal geometric shapes to increase surface area for improved heat transfer to the filament. It also enhances volumetric flow rate settings, allowing for quicker printing. 2、Sturdy And Rugged: Constructed from three different metal materials, the tip is made of hardened steel, the inner tube is TC4 Ti alloy, and the rest is Cr Zr copper, each with varying thermal conductivities. Hardened steel offers high abasion resistant for a longer lifespan, TC4 Ti alloy reduces heating, Cr Zr copper aids in heat dissipation, accelerating thermal conductivity. 3、DLC Nao Surfaces Treatment: The DLC Nao coating provides excellent abrasion resistant, reduces friction coefficients, and exhibits strong erosion resistant, extending the product's lifespan. 4、Wide Compatibility: Our 3D printer extruder hotend nozzle is compatible with 1.75mm filaments and works with for BIQU H2 V2S Lite Revo, for H2 V2S Revo, for RapidChange Revo Hemera, for RapidChange Revo Six hotends, for RapidChange Revo Micro, and more. 5、Enhanced Performance: With advanced materials and design elements, this 3D printer hotend nozzle offers improved heat transfer, faster printing speeds, wear resistant, and compatibility with various printers, ensuring efficient 3D printing results.
