For vat coatings I experimented a bit with aquarium silicon (inexpensive but dificult to apply and didn't last) and Teflon sheet. The teflon worked well but the sheet I got was very thin and fragile. I also had trouble getting it to adhere to the glass. I may try the adhesive backed fep from McMaster. For now the Sylgard is working for me. I wish it was more durrable but I coated several pieces of glass last time so I'm set for a while. The Sylgard is expensive but I should be able to coat many 4x6 pieces with the small tub I got.
If you think about it:
Pulling one edge down like the traditional motorized tilt is mechanicaly no different then holding one edge and lifting the platform up. The forces exerted on the cured layer are the same.
The difference is fewer moving parts. Just some home hinges vs hinges, a mechanical linkage, stepper and driver.
I'm still tweaking the resin/exposure to get the best detail but you can see the passive tray tilting is working fine
