Fill missing in random places

What slicer are you using?

It looks like a classic thin wall problem where the slicer thinks it cannot fill in the remaining gap after finishing the perimeter passes. Making your letters slightly bigger might get rid of this problem.

But on the other hand it looks like a pretty big gap so it shouldn't be a problem (hard to tell by just a picture though) and the rest of the letters look fine. Could there be an issue with your model perhaps that is causing this issue? Try running it through Netfabb's cloud service and repair the model.

In cura always look at your model in layer view before printing so you can see problems like this. You need to play around with Cura settings until it looks correct (fills in the A). Also look in xray view from different angles - if you see any red walls in the A then that is your problem and it might be fixable with the "fix horrible A" setting.

In cura make sure solid infill top is checked (expert) and nozzle size is .4.

Then try shells of .4, .8, 1.2 or even 100mm (that will do 100% infill but in a shell pattern instead of diagonal).

Also consider 0% infill or 100% infill.

Basically, play around with cura settings before you try to print it and let us know what fixed your particular issue for the next person. Is it possible you are using a year old version of cura (which had more problems with thin walls)?

gr5 mentioned everything already, but If nothing helps, you could also fake the nozzle diameter on this model since it's pretty simple model (no overhangs). Try set it to 0.3 - 0.35 and check the layer view. This sometimes helps me if i print small letters and the top surface got small holes on sharp edges.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
