Be sure to clean your build Platform and your resin tank. It must be perfectly transparent or the laser will fail to polymerize. Also the mirror must be perfectly clean!
Remember to change your resin tank every 2 Lt of polymerized resin.
Hi, good news for me. But I wonder if I could clean the inside of the tank with the rainx as I want to change the resin but don’t want to buy an extra tank, the tank is expensive in my country, So did you hear someone used it to clean the inside?
I’ve recently started using a resurfaceable glass tank (z-vat) so have switched resins often. You don’t need to fully clean the tank each time you do it, using the scraper to carefully scrape the resin out is generally enough as I’ve not had trouble with the tiny bit of resin left mixing. I have experimented with cleaning the original tanks and it made them perform worse. I’ve had formlabs tanks fail well before they’re hit 2l resin which is why I got the glass tanks.
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.
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
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.
