Nozzle diameter

Recommended Posts

Yes, you can, but the print times will go up a lot, as you will not only have to make more passes of the head to cover the space, but also you will need to print slower - in proportion to the square of the nozzle size (i.e., proportionate to the area of the nozzle opening). Smaller openings need higher pressure to squeeze the plastic through, and in order to not overtax the extruder drive, you need to print hotter and slower.

I think somewhere between 0.2 and 0.3 is about as small as you can practically go on an Ultimaker.

You could also experiment with setting the nozzle size a bit smaller in Cura without actually getting a smaller nozzle. That will make the slicer try to print finer details, extrude less plastic, and generally behave 'as-if' the nozzle was smaller. Of course it won't actually be smaller, so that avoids some of the pressure/speed issues, but may lead to a less well-defined bead of plastic being laid down.

If you are printing something larger than your smallest finger with a .25 nozzle - well - then you have more patience than me! These links are pretty good - but I think the first link is better.

.3mm nozzle on ultimaker - finer but slower:

    • Ultimaker Cura | a new interface
      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
