100% infill with Cura

[chemwhite 0]

When I use 100% fill in Cura, part of the object is filled 100%, but part is not. I assume that this is due to spacing out the lines so that a whole number of lines is spread evenly across the area (even if the lines have to be farther apart than woudll give a 100% fill). I need to print some parts to be used in a test involving the thermal conductivity of the plastic (using a filament with a proprietary material), so having a bunch of small voids in the plastic is undesireable. Any suggestions on how to get a true 100% fill. Note: An overfill condition could be acceptable because the excess material could be cleaned up, where the voids cannot.

Thanks guys

You can adjust the infill overlap in the expert settings, but you will always have some gaps.

that is not true... I print with 0 gaps, I have complete solid infill (15% overlap

Oh, yes, it also depends on the model. And you need to have proper belt tension.

Problem solved! I used a nozzle diameter of 0.254 mm, and filament diameter of 2.7 mm (actual is 2.82), and printing speed of 50 mm/sec, an infill overlap of 25%, a layer thickness of 0.12 mm (with skins enabled), and a print temperature of 215 for the gray PLA that came with the Ultimaker machine. This gave a very nice 100% infill without voids.
