DLP printing similar to photo-etching

[San]

Hello everyone, I'm going to buy a DLP printer to be able to print elements resembling photo-etched elements. Unfortunately, after watching this video-https://youtu.be/pbYAhjASGFYI began to doubt that it is possible at all without breaking down in the next layers. because a very small element must be printed horizontally. I noticed that the printers have a single layer thickness of 00.1mm to 0.30mm. My question is if I make the thickest single layer, will I be able to achieve it? It will not be a typical 3D object but a plate with an ornament, looking like this-https://imgur.com/a/E06VIt5 if it fails, it is possible to print directly on the plate where 3d printing begins, e.g. covered with some foil so that it can be easily removed?Thanks for every reply!
