Looking at all the MSLA printers on the market, it seems that, hardware wise, everything is already there. The real concern is controlling the additional motors and print process. It's not like the Z axis and all the other motors need to be precisely timed within microseconds, so it sounds plausible that 2 controllers could be used: the first one as part of the doner printer that deals with the z axis motor and the LCD, and the second one for all the additional features needed.

From research, it seems that anything with ChiTuBox's controller and features a 4K or larger display will need an SDK, for which I'd have to apply for. I'm skimming over the free use agreement but I don't have high hopes by attempting to go down this route.
