Has been patented by Light Sculpting.
Research is going on at IKP, University of Stuttgart, Germany.
Problem: Long-term stability of LCDs exposed to UV light.

You would need a Zoom !
Problems: The special UV-optics would cost as much as the whole SLA
machine today or more; and you would loose speed.

No idea if this could work.
A Laser solution is still easier to handle.
