You know those wallpaper glue applicators?

They're basically a drum that picks up blue from the reservoir. Now imagine this for 3D printing upside down, on its side or even in normal orientation.

Since we've developed an essentially flatbed linear light engine, we might as well put it inside a precision glass tube (BK-7 or better) and expose some resin from the inside.

The glass tube would be moved back and forth, all the while being rotated synchronous to the motion to roll over the topmost printed layer, making contact, adjusting resin layer thickness and peeling off in one go.
