MK8 Nozzles 0.25Mm 3D Printer Extruder Nozzle For 1.75Mm Filament Pack Of 4

What is this?This product is a stainless steel MK8 nozzle designed as a replacement part for a 3D printer extruder. Crafted from durable stainless steel with a smooth inner wall, they offer great heat and corrosion resistance, ensuring stable performance. Their precise design allows for smooth and consistent filament extrusion, making them suitable for various 3D printing applications.What will I get?The 3D Printer Extruder Nozzles, we provide here, are in the size of: Nozzle Diameter: 0.25mm; Overall Size(LxD): 13x6mm/0.51x0.24inch; Screw Thread: M6; Fit Filament Diameter: 1.75mm; Color: Silver; Package Content: 4 Pcs x Nozzles.Is there any advantages of the product?The MK8 nozzle's precise design ensures even and accurate filament extrusion, enhancing the surface quality and detail of printed models. Its inner wall is smooth without burrs and has a low viscosity coefficient, while maintaining stable temperature during printing to allow filament to be discharged evenly, helping improve printing speed and accuracy.How to use it?1. Turn on the 3D printer, heat the nozzle and heat block to the target temperature (PLA: 180-220, ABS: 240-280).2. After heating finishes, close the printer, and take the spanner to hold the heat block. Then use socket screwdriver to screw the old nozzle extruder out.3. Spanner keep to hold the heat block, use the socket screwdriver, screw the new nozzle in, and make sure tight.What should I notice?After replacing the nozzle, please recalibrate the distance between the nozzle and the build plate to ensure the quality of printed parts. Do not touch the old nozzle and heating block during replacement to avoid burns.
