Description <br> Fit For 3D Printers Models: The nozzles kit is compatible with for K1/K1 Max/ 3 V3 KE FDM 3d printers, please confirm your 3D printer model before ordering. <br> Support High Speed Printing: The nozzles kit contains brass materials, high thermal conductivity, high thermal conductivity enables the filament to be heated evenly; at the same time, the internal volume of the nozzle is larger than ordinary nozzles to support 600mm/s high-speed printing. <br> High Temperature and Wear Resistance: The nozzles can withstand high temperature up to 500 ℃, fast thermal conductivity, make printing more stable; process with good electrical conductivity and anti- and rust, greatly reducing the adhesion between the filament and nozzle, extrusion is smoother. <br> High Quality 3D Printer Accessories: Nozzle inner wall roughness Ra Less than 0.4, reduces the chance of clogging; advanced heat treatment process, so that the nozzle has better resistance, can extend the service life of the nozzle. <br> 10PCS 3D Printer Extruder Nozzles Kit: Input diameter is 1.75mm, output diameter is 0.4mm, included 5pcs 0.4mm, 1pc 0.2mm, 1pc 0.6mm, 1pc 0.8mm, 1pc 1.0mm and 1pc 1.2mm brass nozzles. Replacing the nozzles regularly give you a better printing experience. <br> <br> Please note:the physical slightly color difference or difference, does not affect the use, please do not mind, thank you! <br> Colour:As Shown <br> Material:brass <br> <br> Package Contents: <br> 10 * 3D Printer Extruder Nozzles Kit <br> <br> Only the above package content, other products are not included. <br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
