So every couple months I clean my resin contaminated alcohol using alum powder (link to a video about the process)

After cleaning it I let it sit in the settling containers until I need to clean my alcohol again. At which point I swap the alcohol that was cleaned into my main wash and cure station tub and then put the dirty alcohol into the other tub I use exclusively for cleaning the alcohol.

Edit: For those curious I can share an image of what the alcohol looks like after it’s had 24 hours to settle in the settling containers.

    Resin printing remains somewhat of a mystery to me since I don’t have a resin machine and nor does anyone I know. So it’s always neat to see these insights into parts of the process and work flow I’m not familiar with.

      That’s pretty much how it was with me until I ended up being the first of my friend group to get one

      It’s been an experience for sure but it’s been a welcome learning experience

      Though if you do get one someday be sure of one thing above all else, safety first. Never slack on safety because “oh how bad could it be?” The answer is really bad.

      Also you will use a crap ton of nitrile gloves. Like an absolutely comical amount.

      Usually I can see it start settling while it’s mixing but it doesn’t fully settle during mixing

      Usually I’ll be able to see a noticeable difference in 24 hours but I’m actually not fully sure

      If I don’t notice it settled enough within a couple weeks I’ll add a bit more concentrated alum solution to each settling container and shake the hell out of it

      But in general having one container worth of alcohol settling while the other one is able to use is a good idea because settling can take awhile if the alum solution isn’t very concentrated

      Edit: By concentrated alum solution I mean like 25 50 grams per 100ml of distilled water, it should fully dissolve before you add it to the alcohol.

      Edit 2: I double checked my notes, it’s actually 50g per 100ml. It helps to mix it of the water is warm (NOT BOILING!!! ONLY HEAT THE WATER!!! And have it just warm enough to dissolve the alum. Then wait for it to cool down a lot, like barely warm.)

    How many prints do you think you’re putting through before you’re cleaning it.

    I run mine through a porous rock filter (I’ll try to find the video link) every couple of months.

    Typically I pre wash with Mean Green, then into the isopropyl which helps extend the life of the isopropyl.

      No idea unfortunately, I typically only print a few build plates of models a week and then it’s a few months between cleanings like this
