The upgrade is based on the great team of E3D, and the detachable design concept is carried out.Based on the fact that the throat will fall off, we have added steps.Moreover, we found that it is very troublesome and costly to replace nozzles of different calibers during use, so we came up with the idea of detachable nozzles.Thereby upgrading their products, thanks a lot for their great design.At the same time, when printing high-temperature and high-loss consumable abrasives, the material has also been upgraded, and the hardened steel material coating process is adopted. At the same time, the hot-melt section uses copper material to make the heat conduction more efficient and has been ideally solved.Welcome to order our upgraded Revo throat nozzle, choose our 3D printer accessories, enjoy higher precision and smoother printing experience, and release your imagination.
