I have printed two clutch hubs, first with full infill and then with medium infill. You might be interested to see the difference using full or medium infill concerning deflection and accuracy of the part. The deflection when using full infill is significant and to such a degree that the part is not usable. I reprinted with medium infill and things were much improved. This is of course due to the smaller mass of the part, thus less material shrinkage which again leads to deflection/warping. The model is for light testing only, so the medium infill part is usable. Same printing parameters for both parts; closed box around the printer and ABS/acetone mix on the perforated plate. Material Z-ABS, layer 0.19mm.
