Feature: 1. APPLICABLE MODEL: 3D printer nozzle kit with high flow rate, high temperature resistance, suitable for Anycubic Kobra 2 Kobra 2 Pro Kobra 2 Maximum Kobra 2 Plus, can directly replace old or damaged 2. HIGH SPEED PRINTING: Brass thermal conductivity up to 330W/m·k, to ensure that the nozzle is heated more evenly. The volume is twice that of the ordinary nozzle, support the high speed printing speed of 600mm, uniform ni plating, greatly reduce the adhesion of the filament to the nozzle, and the extrusion is smoother, the surface is plated with Ni layer, and the extrusion is smoother 3. APPLICABLE MATERIALS: 3D printer brass hotend nozzle is suitable for most for FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., as well as PEEK, PEKK, PEI, PSU, PPSU and other high temperature filaments 4. HIGH TEMPERATURE WIRE QUALITY TREATMENT: Brass high temperature resistance up to 300℃, to ensure high temperature wire rapid heating and continuous printing 5. HIGH ACCURACY: The inner wall of the volcano nozzle is smooth without burrs, the viscosity coefficient is high, the extruder diameter error is less than 0.02mm. Whether you're printing regular filaments or more challenging materials such as carbon fiber and glass fiber, offer you accurate and smooth extrusion Specification: Item Type: 3D Printer Brass Nozzle Material: Brass Filament Diameter: Approx. 1.75mm / 0.07in Screw: M6 thread Size: Approx. 7 x 21mm / 0.28 x 0.83in Maximum Printing Temperature: 300℃ Application: For Anycubic Kobra 2 Series . Package List: 3 x Brass Nozzle
