0.4 mm nozzle as standard For most 3D printers, the 0.4 mm nozzle has become the standard, as it is usually installed as standard and offers a good balance between resolution, precision and printing speed.

You can't go wrong with PLA for a 0.4 mm, but another filament, like carbon fiber for a 3D printer, works well with a nozzle in the 0.4 mm to 0.6 mm range. When it comes to buying filaments, trust is key. Choose a reputable brand like Filamatrix for expert guidance on each filament's performance.

The standard Ender 3 nozzle size is 0.4 mm in diameter, which is the most common size and suitable for a range of prints. Small diameters create thinner lines of filament (better resolution) at the expense of printing speed, while large diameters can push out more filament at a time at the expense of detail.
