It would be awesome to have the ability to print at different resolutions by section of layers in the model. For example, I would love to specify layers 1-800 to be at .1 resolution, and then layers 800-1200 at .05. (i know # of layers changes depending on the resolution, so maybe you slide the layer slicer and tag the resolution using that)
My reasoning is that sometimes I have pieces that are large, that for the most part could be printed at the low/fast resolution, that also contain a section of higher detail. A character would be a good example, the body doesn’t always need as much resolution, but around the face and eyes would be good to have. This could keep print times lower, while giving detail where needed.
