Features: Available in three materials with high-temperature resistance, wear resistance, and explosion resistance, offering good thermal conductivity. The joint fits tightly and contact surfaces are flat, effectively preventing material leakage from the print head. Round feed chamfer aperture and smooth nozzle surfaces reduce resistance, helping to avoid issues such as inconsistent filament flow and clogging. Inner wall is smooth and free of burrs, with a low viscosity coefficient for smoother filament extrusion. Made using a one-piece molding process with precise craftsmanship, designed for compatibility with AnkerMake 3D printers. Specifications: Material: Metal Type: Stainless Steel, Hard Steel, Brass (optional) Nozzle Diameter: 0.4mm Filament Diameter: 1.75mm Compatibility: Suitable for AnkerMake 3D Printer Note: Please allow 0–1 cm error due to manual measurement. Slight color variation may occur due to differences in display resolution. Package Includes: 1 x Extruder Print Head
