What type of infill do you use?

[printbus]

I use Cura as my slicer now, so I don't get to choose. When I was using Slic3r, I tended to use rectilinear more and more as I went along. As CaptainObvious suggests, linear or rectilinear are "easiest" for the printer to do since they involve straight line movements. I grew to realize that on large, dense parts the majority of the print time is spent on infill. Most people orient parts square on the print bed and then rotate the infill (say to 45 degrees). I found that by rotating the part instead so the infill orientation could be set to 0 degrees, prints would go a lot quieter (only one motor moving during an infill line, and its only moving in one direction) and get done a lot quicker (maybe reduced by 25%?).
