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.

    I’m my case, the alum has never settled on the bottom of the container. I gave it about two weeks, give or take. How long do you wait for that to take place?

      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 grams per 100ml of distilled water, it should fully dissolve before you add it to the alcohol.

    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.
