FWIW, but not to nitpick, if you really want print speed then look at
top down projection with an LCD or DLP.
https://i.imgur.com/zvxoHUT.jpg 200um XY at < 2 seconds per 100um Z,
using 4k DLP
https://i.imgur.com/b4zPwKo.jpg 1-10um XY 0.1-1 seconds per 100um,
using 4K DLP and inverted microscope. As shown it was printing at ~25um
XY <1 sec. / 100um Z.
Bottom up is always slow if it's not layerless like CLIP or HARP. It
also places strain on each layer when it separates the print from the
vat. Cooling LCD's is also not a problem. High temp LCD's for projectors
have also been around for over a decade.

If you want to make a profit then you also need to make your own
photopolymers.

My medium format S Box printer was among the first monochrome LCD
printers. It's faster than the 3D printers that use cell phone LCDs,
and the technology is more reliable in general but probably not in
this particular case, given that it was among the first. A year
later, hopefully the 3D printer manufacturers have worked with the LCD
manufacturers to produce monochrome LCDs that are optimized for MSLA
3D printing, with high resolution, better thermal management to stay
cooler when sitting on top of a very high power UV LED array, etc.

The technology to look for in LCD resin printers is a high resolution
monochrome LCD. They allow much more UV light through than the color
LCDs and last longer before degradation from the UV light exposure
ruins them. But since these printers are pretty much the only reason
to revive old mono LCD technology, they come with a premium price -
but the per layer speed is considerably higher.
