The UV beam sets resin about 6μm wide. Prusaslicer doesn't allow a layer height of more than 6μm for that, but the UV goes on for a lot further. So I have adapted fibre_process.py to use a Z_SCALE constant. This allows the model to be compressed vertically by, say, 50% in Prusaslicer and then be expanded to full height again in the filter to produce the full-height GCODE. Here's a Benchy printed that way:
If you zoom in you'll see that we have lost a bit of vertical resolution. However we have also gained resolution under overhangs, because there is less cumulative UV overshooting the edges. So Benchy's hull has more of a curve to it.
While the use of this is debatable in creating artistic models, for the grunt work of creating more or less planar mechanisms with little if any overhang it means I can print them twice as fast. Possibly more than twice.
