[Quality] Make of high quality brass materials, with higher thermal conductivity ensures uniform heating of the nozzle and smoother extrusion. Improve the structural strength of layer-to-layer adhesion, which greatly levels up the printing quality. [Precise Design] 3d printer nozzles can prevent the print head leakage effectively and produce consistent prints with smooth and glossy polish. Reduce the resistance from the corners and avoid blocking the filament with a rounded chamfer. Easy to identify with engraving the size on each nozzle. [High-Temperature Resistance] The max temp of this high-end copper alloy nozzle could reach 300℃, suitable for 3D printing at high temperatures, applicable to most FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc.and , PEKK, PEl, PSU, PPSU and other high temperature filaments. [Extensive Compatibility] Compatible with for a variety of models, including for Pro// V2/-5/-5 Pro/-5 Plus/-3s/-6/-4/ Max/-2 Pro/-2/-10S -10/-10 S5/-10 S4/-10Mini/-20/-20 Pro<br><br>Colour:Copper Color Material:Copper Size:0.25/0.4/0.6/0.8mm<br><br>Package Contents: 8 * Printing Nozzles<br><br>Only the above package content, other products are not included.
