1、[Compatible Models] This kit includes 10 pieces 0.4mm brass nozzles, specifically designed for Neptune 4 and for Neptune 4 Pro 3D printers. 2、[High Speed Printing] The 3D printer brass nozzle enables high flow and high speed printing, supporting fast print speeds of up to 600mm. 3、[High Temperature Resistant] The extruder nozzle ensures rapid heating and continuous printing of high temperature filaments, as brass can withstand temperatures up to 300℃. 4、[Uniform Ni Plating] The even ni plating on the surface significantly reduces the adhesion of fine metal filaments to the nozzle. Smoothly inner wall without any burrs ensures smoother extrusion with reduced viscosity. 5、[Wide Material Compatibility] These nozzles are suitable for most materials, including PLA, ABS, PETG, TPE, TPU, PC, as well as high temperature filaments such as PEEK, PEKK, PEI, PSU, PPSU. Item Type: 3D Printer Nozzle Material: Brass Nozzle Hole: 0.4mm Filament Diameter: 1.75mm Screw: M6 Thread Maximum Printing Temperature: 300℃ Compatible Filament: 1.75mm PLA, ABS, PETG, TPE, TPU, PC, etc. 10 x 3D Printer Nozzle Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-YJL official store
