Smaller nozzle?

Hi Everyone.

In my eternal quest for finer and higher quality print, i stumbled upon someone talking about 0,2mm and 0,15mm nozzle sizes, and that got me thinking.. Has any of you tried a finer nozzle, and if you have, where du you get one?

Another thing i wanted to share with you, is that, i have had a few things printed at my local 3D printer guy BU (Before Ultimaker), at a very high cost, because of the very expensive machines he own and the very expensive filament he uses.

I told him that i have bought a "reprap" printer and he kind of padded me compassionately on the shoulder with his nodding/ half smiling/patronizing expression. Now i have had my Ultimaker for about three weeks, and the prints are getting better and better.

The other day i went to show him a print that i made on the ultimaker - a print from the same file that he printed for me on hi's machines just a few month's ago. I just loved the way his expression went from patronizing to utter disbelieve!

The model i showed him, had better resolution and was much stronger than his ABS printed model... I could tell that he felt sick yo his stomach :lol: - well you should'nt kick a man who lying down, but MAN THAT WAS FUN!! :lol:

Anyway, any feedback on my question is appreciated.

Thank you.

    I've heard of people using 0.35mm but nothing smaller. There'd be lots of bowden tubes a poppin' I should imagine?

    AFAIK, the UM standard nozzle is 0.35mm. you can check it by extruding some filament into mid air and measuring the string that comes out of the nozzle. (my makergear nozzle is nominal 0.5mm, but 0.56 in reality).

    using a smaller nozzle works just fine, you just have to change your expectation how many mm^3/sec you can squeeze through the small hole (which involves just going slower), other than that, it's no problem.

    really? Cura is defaulting to 0.4mm nozzle size - so I've been assuming that's what I had!

    Says an 0.4mm nozzle. But it could be slightly smaller I guess. Maybe they mean "a nozzle that prints 0.4mm lines optimal"

    extruding in air will stretch material a little bit because of gravity , and after that you have shrinkage when cooling , thats total maybe max 3-5% my guess

      • 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.
