In the mean time check out the write up on how the vat works:
I printed this on a larger version of the vat:
Model:
140mm long without supports, .05mm layers, wt. 86g, makerjuice sf, took about 10 hrs to print
Note: the line about 2/3 the way up from the base was caused by me bumping the build plate while adding resin to the vat

The first eiffel tower in the photo was printed using the v5 vat with .1mm layers and .063mm x and y resolution, the second tower was printed with 0.05 layers and .0.63 xy resolution, they are both 100mm tall (the .063 xy resolution is a compromise resolution on my test rig since I am also testing other vats, if I have time this week I will run some tests at .025mm xyz resolution and post the results.). The surface finish of the parts I have printed has been very good and I have had no print failures when using 2 build plate attachment layers exposed for 30 second each. The outer handrail at the first platform of the .1 layer thickness eiffel tower did pull away but I don't consider that much a failure since the bars holding up the railing were hair thin 0.07mm diameter rods (about 1 dlp pixel in size) and they did in fact print, the inner hand rail printed ok.
The photo of the disassembled vat show the main components: top plate/vatwall, base plate with molded in threaded inserts (no more spinning threaded inserts), acrylic FEP support plate with tape and vents, snap in retainer for mounting the support plate, printed mounting thumb nuts (or screws depending on the printer). Not shown are misc bolts, gaskets and FEP film (the gaskets and FEP film are the same as those used on the drumhead vat). The vat can be mounted to the LittleRP, LittleRP2 using 2 or 4 mounting points or custom printers.
I should have the v5 vat kit available at flexvat.com next week sometime, the kit will come with the components described above, any needed mounting hardware, 4 laser cut FEP windows, 4 laser cut gaskets, a spare acrylic FEP support plate and spare snap in retainer. I have not determined the cost for the kit yet but it will be comparable to the v4 vat.
0.1mm z, .063mm xy, printed straight
.05mm z, .063xy, printed angled 6 degrees

I made something crazy and found the solution for me.
I have on the side, on which the FEP foil rests, sanded the acrylic plate with a very fine sandpaper (800..1000), diagonally crossed (only one-sided!).
The FEP foil now does no longer adhere to the acrylic floor.
In the edge area, I made holes in the acrylic floor to ensure, that the FEP foil is vented.
But the FEP film has then to be tensioned, then it works almost like an one-sided Flex-Vat.
At my resolution of 100 microns in XYZ direction I could not notice any impairment of the printing quality,
also the exposure time remained the same.
Now I can exposure the total area of 192x108mm at once , and there are no more problems with the peel process,
and this without tilting.
Previously, this was impossible, also with Tilt.
The distance for the light scattering between the polishd side of the acrylic plate to the exposure layer is here only the thickness of the FEP film. However, I can not say how this works with lower resolutions in XY.
For my needs, however, it was the final solution.

Can you tell us what is the distance from the focal plane to the bottom of assembly?
Depicted is the unsupported configuration, correct?
