I get its a photo-sensitive resin that cures at ~350-450nm wavelengths, and that arc projectors can output those UV numbers. My question is, if the process is halfway through printing a hollow sphere, for example, how does the projector focus and cure only the object needed and none of the liquid resin between the projected image and WIP sphere.
