I treated my prints with IPA 70% for 30 seconds; water and UV postcuring for 2 minutes......after that appeared some white spots...anyone knows why?

First off all I added some central supports to the base of the vat to support the FEP film...but using a build plate 130x80 mm was not sufficient.
So i decide to use a smallest build plate 70x50 mm.

In attached some photos of a dental bridge (xy: 58 micron; z: 50 and 100 micron).

I think that the next step will be to test:
1) Placing acrylic ( 3mm thickness) under the FEP (not tensioned);
2) Using a microforated build plate

My build area is 125x70 mm max but the dimensions of the vat are calculated for a 0,71 liters.

One thing I would add is a longer pause after the build plate comes down and before exposure to allow the resin hydraulic pressure to equate. Very nice vat, what is your build area?

I made my first print with 0,1 layer thikness and everything went well!

From the second print i have some problem becouse the prints don't fix well to the base of the print plate.
As you can see from the VAT_SECTION image, the problem is that the weight and viscosity of the resin do bend the fep tape at the centre of the vat. So when the print start the first layer is not fixed to the plate.

Any suggestions?
