Some filaments can wear away the nozzle of your printer faster than others. Filaments that contain metallic particles or Carbon fibre particles like XYZ Metallic PLA and XYZ Carbon PLA will wear away your nozzle so that the diameter of the nozzle changes affecting the accuracy of your 3D prints. This is wear using a HSS nozzle comes into play as it is more abrasion resistant than the standard copper Da Vinci Super extruder. The Hardened Steel extruder can last up to 100 x times longer than the standard copper version.
Improving print performance for Carbon and metallic filaments means you can print strong and durable parts on your Da Vinci color, for example carbon fiber Drone components. Or alternatively make use of metallic filaments to print aesthetically pleasing metallic sculptures.
