100% infill with Cura

Recommended Posts

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 :D

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.

    • 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.
