Easy upgrade for trouble-free printing of hard composites! Our Plated Brass Wear Resistant Nozzles are made from brass for good thermal conductivity and plated with an extremely hard high lubricity coating. The coating increases the life of the nozzle significantly. We have yet to wear out a nozzle! With normal brass nozzles noticeable wear can occur after as little as 500g of Stainless Steel material. Currently available in: 1.
