Hi everyone,
I just got an Elegoo Saturn 2 and did one successful print and tried another but ran into some issues after it printed.
I’m using a water washable resin for both prints. Also using the Elegoo Mercury wash and cure machine for this.
Once the print finished, I put it into the wash with water and let it spin for 3 minutes. I took out the print and let it dry off on a metal plate. Then I moved it back to the Mercury to cure under the UV lights. Once it seemed cured, I began removing the supports.
This is a fairly big, heavy object that was being printed. This is the object here https://www.thingiverse.com/thing:2482299
I titled it on its side in the slicer so that the full object could fit on the bed and used the default settings with medium supports.
One issue is that the color turned a cloudish color. To my understanding, this is because I didn’t let it dry enough after the wash before curing. Is that correct or is there another reason for that?
The second issue I had is that there was a few layer shifts in the print. Here’s a picture of the layer shifts https://i.imgur.com/eV5XSxN.jpg https://i.imgur.com/TKAFD1x.jpg I did once knock the printer which I know can cause layer shifts. But I’m seeing more than one layer shift which leads me to believe something else happened. What else could cause layer shifts besides the printer being physically knocked?
The third issue is that the very first layers of the print are coming off. Here’s some pictures of this https://i.imgur.com/CrFdExh.jpg https://i.imgur.com/fKpff9G.jpg my thinking is that maybe this is because I didn’t choose heavy supports since this was a larger object? Could that do it? But what would cause this part to be flat too? It’s supposed to be rounded, but after pulling the supports, this area is flat despite it being elevated from the bed to be held by supports.

True, the sticking can be quite the hassle. I personally (carefully) sanded down the metal print plate, as to make it more rough and therefore more sticky, and then bought some new film from fepshop.com which should be less sticky than the original on my Elegoo Mars Pro 1.
That worked really well, minimizing layer shifts quite a bit and allowing me to use less supports without the print going haywire.
