Yes, you could modify the project with a bit thicker spacers to get down to probably 20 microns (smaller build area, of course). At some point, you physically will not be able to get the projector close enough for this to focus. And of course, the modified projector will not be able to achieve 70 microns for larger prints.
Our software reads a configuration file to understand the projector, so it could handle whatever you changed it to.
This would be a total DIY, we don't have time to support those types of experiments.
