Random nits on surface


Recommended Posts

Posted · Random nits on surface

I am trying to print this file, but Cura is adding little "nits".  Simplify3D does not do this with the same STL.  How can I correct this?


The model has a raised logo - you can see text at the bottom, and then little dots below randomly - those should not be there.


I've tried many settings relating to surface, but none really seem to fit the issue.

    You didn't save it as a project, so I don't quite know with what settings you actually sliced it with.

    I think you need to enable "print thin walls", since the letters below the logo are pretty thin.

    The horses legs and the lower text are so narrow that slicing is problematic.

    Here is Cura 4.10 using the project file.  I changed the line width to .35 and enabled Print Thin Lines.  It is better but there are still discontinuities.



    Here is what I got with PrusaSlicer with Detect Thin Walls enabled and all line widths at .35.  This looks much like the 4.10 preview as the legs and lower lettering are incomplete.



    This is with Cura Arachne (which I think is the best slicer choice).  This is with a .3 nozzle at .28 line width.  I thought it looked pretty good.



    Your current setup has horizontal expansion at -.02.  That is part of the problem as the legs and lower letters get even thinner.

    Using Arachne with .2 nozzle and .2 line width and horizontal expansion at +.01 finally looks very acceptable in Preview and the print time isn't too bad at 3hr15min.  I know it has doubled the print time but fine lettering (and horses legs) are tough to get right.
