Nozzle diameter

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:


    .2mm nozzle

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
