How do you recycle your IPA alcohol for 3D printing
How do you recycle your IPA alcohol for 3D printing
Today i made a test on recycling my Iso alcohol tank after a long time, about 30 prints has been done.
I tried the sun light method, filled it in a clear plastik bottle and the first try was on the curing machine which works out more less then awaited.
2L of IPA turned into a mucous mass like morzarella cheese
I tried to filtrate that mass, but no success, i only got 300ml of milky Iso back, the rest is covert into the Morzarella.
I mixed all up and put it back into sunlight and will check it later again, but i`m not expecting a better result next.
So how do you recycle your IPA after while?
Seen on Youtube someone trying to destilate it again from that mass, but as i don`t want to blow up my house, this method is not my favorite!

Greetings Thomas
Re: How do you recycle your IPA alcohol for 3D printing
Thank you Thomas, but this is the video i watched
There is one thing that is not shown, what happens with the bottle after heating? I think you can put it on the dump, he does not show what the rest of the destilated material is like, and i find it a bit "unsafe" to do.

For a minute I thought this was IPA beer.

Ok, after another day in sunlight nothing has changed and the mass is close to the same as yesterday.
All Youtube videos i watched ended up in this mass and don`t work out well, destilation is surely a way, but to much risk to me to do it at home.
Good news is that my new order of IPA is arriving today and i can move on

Also did not find a good solution for that.
Only Mozzarella in the bottle. That is all I get.
5 Liter of ISO and I got 0,3l clear ISO back. The rest is Mozzarella.
Now I filter the ISO once a week and use a second wash and cure.
That's my solution. And always the finger on the trigger to order new Iso.

I will give that a try, first wash in a cup to get rid of most resin, and then the washing station with clean ISO/IPA.
I filled my 2L of mass into an old resin bottle now and will bring it to a company for "special waste".
Another 5L Iso are ordered right now cause your right, running out of it is boring when you are printing.

Re: How do you recycle your IPA alcohol for 3D printing
You need to let the resin/IPA mix settle, both before and after exposure. If you do it when it's thoroughly mixed, you'll get a congealed blob; let the liquid sit for a few hours (minimum) first and you'll get a mostly clean alcohol layer on top of a thicker resin mix. It also helps to do it somewhat frequently - it's possible you just had too much resin in your solution.
The other alternative, which is gaining popularity, is distillation, but IMO you'd have to go through a ton of IPA before you start making up the cost of the equipment.

Je ne regrette rien.
