Hello, which kind of tank are you using now? or you just remove the silicone and add the glass in it? maybe I can do it too, I have already get two resin tank wasted, I can modify them.

That’s strange… You tried just replying to my email too?

We’re using z-vat 3rd party vats which have silicon coated glass bottoms, but the plastic vats are recoatable too, have a look at the DruckWege ReCoat kits

Thanks for the information, I will check it right now.

That is a worn-out tank right there I’m afraid. Did you print the model in the same position several times? Looks like the area corresponding to the support points has suffered burn-in. You need to try to avoid printing over the same position as much as possible, and in general the tough resin seems harder on the tanks than other resins in our experience, which is why we got the recoatable z-vat glass tanks

I had the silicone layer in a tank that I had used for a short time delaminate from the tank. It allowed resin to seep between the silicone layer and the tank. I could not get anything to build at all. The cured resin beneath the silicone absorbed enough of the laser energy to prevent curing. The tank looked clean and smooth just nothing would build. Had to replace the tank. My guess is the same thing would happen if the resin got on the outside of the tank. Just wiping it off might not be enough to restore transmittance. If you clean it with alcohol just be sure to use virgin alcohol right from the bottle not contaminated with resin from the rinse tank.
