One of the most important parts of the 3D printer: the nozzle. The nozzle lays down the filament in layers. Over time, the filament causes wear on the nozzle, making it "wider" and less accurate for printing.
After a lot of printing, it is advisable to replace the nozzle. You can also replace the nozzle with one that has a larger diameter, allowing you to print faster, or with one that has a smaller diameter for more precise printing. In addition to "regular" brass nozzles, we also offer stainless steel nozzles, which are more wear-resistant.
