Why Nozzle Size Matters for 3D Printing and How to Choose The Right Size

As a 3D printing enthusiast with over 20 years of experience, I often get asked about the importance of nozzle size when it comes to 3D printing. The nozzle is that tiny opening on your 3D printer’s extruder that is responsible for laying down the melted plastic filament layer by layer to create your print. While it may seem insignificant compared to more prominent components like the hotend or print bed, the nozzle plays a critical role in determining print quality, speed and overall performance.
