7. Nozzles

Your nozzle is where the rubber meets the road, or at least where the plastic meets the print, when it comes to 3D printing. It’s worth spending some time fully understanding the impact your selection of nozzle sizes and types has on prints, and what the advantages and disadvantages are of different features. More expensive doesn’t necessarily equate to best, and cheap isn’t always the most economical.


These notes are based on my experiences with the Prusa i3 Mk3 and Artillery/Evnovo Sidewinder X1 printers. If you are using a different printer, please verify the hardware details are similar.

These are my notes based on months of research, experimentation and just goofing around with a variety of nozzles.
