【High-quality material】The extruder print head is made of high-quality stainless steel, strong and durable, not easy to corrode and rust. It is specially designed for 3D printers, can withstand high temperatures, and is not easy to melt. It is an essential printing accessory. 【Different sizes of diameter】MK8 nozzle has five diameters, 0.2mm, 0.4mm, 0.6mm, 0.8mm and 1.0mm. Each style has 3 printer nozzles. You can freely replace the nozzles you need according to your work needs, which is very convenient. 【Compatibility】This thread plated nozzle is suitable for various Makerbot CR-10, MK8 Reprap Prusa I3 3D printers, and can be installed on all 1.75mm PLA ABS 3D printers. It can be used with E3D-V5 and E3D-V6 printers. 【Precision design】The 3D printing nozzle is processed by CNC precision lathe to ensure that the inlet hole and the outlet hole are concentric. The unique molding technology can ensure that the inside of the nozzle is smooth and free of burrs, so that the image is clearer. Contact surface treatment can prevent the print nozzle from leaking. 【Easy to replace】Each stainless steel print nozzle in the kit contains multiple spare parts. If the nozzle is blocked, it can be replaced in time without affecting work efficiency. Our E3D printer nozzles can print evenly without leakage or clogging, so you can get uniform and clean prints.
