After a couple of iterations, the simple home-made tape-sealed FDM printed flex vat for SLA resin printing is working out pretty well. After trying a couple of different techniques, got something that worked pretty well. I recommend using foam VHB tape rather than thin transfer tapes. It seals well and is much easier to remove when you’re ready to replace the film.
