Brass nozzle for PLA lasts 3-6 months. Factors: print frequency, print size/complexity, material, nozzle quality. High-quality nozzles cost more, but last longer. Nozzle replacement requires wrench, 7mm socket, and socket wrench. Heat hot end, unscrew, replace.
3D printer nozzle cleaning frequency depends on usage & material printed, but generally, every 3 months.
Most 3D printers come with brass nozzles, but you may need to change your printer’s nozzle when using abrasive or heat-resistant materials.
There’s an overwhelming amount, and if you’re looking for the best quality nozzles, you need to understand how they are made and what materials they consist of.
When replacing the nozzle in your 3D printer, your most important considerations will typically be the build material and bore diameter. However, you might wonder whether the compatibility of the nozzle with your 3D printer is something you should be worried about.
Changing the nozzle should take less than a minute as long as you have the right-sized wrench and know what you are doing – and I’m here to tell you exactly what to do.
