This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues. Because of this, it is strongly recommended that this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
