A top down 3D SLA, makes more seance then trying to peel it off a vat. Pros - Cons?

The trick is to get resin to flow on top of the newly printed part in time for the the new layer to have something there to cure. There's speculation about how possible their smooth pull / video exposure is.

This one is also suffering "legal delays" 3dprint.com/130939/gizmo-3d-printer-paypal/ seems to be far too common recently.

The other issue is layer height. I can print down to 5um with a bottom up system. Top down: no way.
