Printing in clear for the first time in over a year today, I realized my wash tank, while pretty clean and with fresh IPA, it’s not really clean. Lots of little cured resin bits of various colours sticking to my clear parts.
I started hand-filtering the tank then I realized I have a small 12V electric pump. So I hooked it up to my filter stand, and voila. All the little bits filtered out in just a few minutes.
Just thought I’d post this in case it’s helpful.
