Re: [diy_3d_printing_and_fabrication] Separation method concept from a noob
I'm making one with a 400mm x 600mm x 650mm build area but only 400um resolution, if it works well, I'll update it 200um res, by upgrading projector.
I've made the cabinet,Z axis, and have finished designing multi projector mount. My mate has made slicing software from scratch so we are nearly ready to test it all together. We are projecting onto the open top surface of the vat, so no sticking issues, plenty of patent infringements apparently but currently it is not for profit, though I most likely will sell what it prints so that might be an issue.

Make the bottom of the tank a semi-rigid membrane supported only on edges. Lifting the build part would naturally bow the tank bottom upward and peel the part features from the edge(s).
Additional help could come from a hemisphere that whipped into place and pushed the tank bottom into a non-flat shape
Also making the tank a cylinder might help.
