Recycling IPA Without Distillation (Ongoing Project)

[Eks]

Tried many similar combinations of your idea and nothing worked. The IPA either didn’t fully evaporate in a timely manner or the resin’s residues were a pain to handle.

I ended up with this solution:

Form 3L Issues

Regarding prints on the 3L, since my last post about it, I’ve been doing nothing but print in Rigid 4000. No idea why but after around 20 prints and 8 litters of resin, I have to conclude that ALL prints were absolutely perfect in every way. The largest one I did had ~1600 layers and came out without any flaw. Maybe I got a good tank, maybe it’s the resin itself, but what matters is that it works so I’m using it all I can until my luck runs out. Also, and considering the large amount of IPA /…

Not only it takes the resin out of the IPA but it also recycles it so that it can be reused over and over. 2 hours for a Form Wash basket full of dirty IPA (7 to 8 liters) gets me around 6 liters back.
