On some objects, infill takes 3-4x as long as the shells, and it is something that you never see when the object is done. So speeding the infill process up helps a lot. If you are wanting to do .3 or .4 shells I would put on a .6mm nozzle. Actually the next step I like is 240micron shells with 480 micron infill, with a .6 nozzle. That gets shit done fast and still looks good. Spritz it with a little acetone afterward and good to go....

In S3D under the infill tab, is "Print Sparse Infill Every X Layers" where I would set it to "2", to get it to print the infill every other layer?
