Had an idea to make some prints go faster, when printing at the finer layer-heights. There is really no need for the support structure to be printed at the same layer thickness as the actual part, as such the base and supports can be printed at the faster 0.1mm until just before the lowest feature of the part begins, at which point the printer would switch to the selected thickness. This could result in a significant time savings, especially for small parts at 0.025mm, where printing the base often takes as long or longer than the part itself.
A rough example based on the estimated time in PreForm, and a simple small object I designed.
