I don’t think ChiTu Box needs to do that. Since this is an MSLA printer, each slice is nothing more than a photo mask, not a “tool” path.
But you could be right, Preform might have some algorithms that look at the minimum feature size, and if it goes below a certain threshold, it might merge it with something adjacent to it, or ignore it altgether.
One of the things I was playing with on the Photon the other day was the exposure time. The shorter the exposure, the higher the detail, however, you also get to a point where some of the very fine details disappear altogether. I printed a couple of space marines that looked fantastic, but the exposure was so low, that the support tips were to small to survive the peel forces, and in some places they came off, and some parts didn’t print (technically they printed but became detached so I ended up with a blob of resin in the vat).
I wonder how long until FL releases an Open Mode for the F3, so that people can try fooling around with the exposure/laser power.
