Random Printer Settings in Cura

 

  Fig.1 and Fig.2 below are both the exact same file (lithophane calibration model) and sliced with the same settings with the exception of the "Fill Gaps Between Walls" Option. 

 

You can see in Figure 1 how there are a few gaps in the model where the lithophane will have air inside instead of plastic.  This sometimes can go unnoticed, but quite often it's noticed and can appear as light/dark bands in the print when it's backlit.  Another way it is very obvious is when it's a thin area which is quite often skin (face/arms) and it will appear blotchy.  The reason it happens so often on someones arm or face is because that is the lightest spot in the picture which will set the min thickness when your generating the STL.  When a very light spot changes gradually to a slightly darker spot, the STL goes from .8mm to slightly thicker.  Most everyone prints with a .4mm nozzle which is why .8 is such a desirable min thickness as it's a mulitple of .4.  With Fill gaps between walls disabled anything between .8 to just shy of .12 won't be printed and it'll be air inside the lithopohane, causing blotchy skin and/or dark/light bands in the print.  Now everything I said above isn't 100% true and it depends on how you slice your lithophane and whether or not you use many walls or top/bottom or infill.  Despite what you choose to use there will still be gaps in your model which is why I almost always choose EVERYWHERE for "Fill Gaps Between Walls".  

 

Fig. 2 is pretty self explanatory, it will fill most of the small gaps (less than .4mm), I also like to uncheck "Filter out Tiny Gaps" to maximze the amount of plastic going down each layer.  Some models you can play around with these settings and look at your layer view, slide it from layer 1 all the way up to the top layer and look for gaps.
