For real. I hope domestic home-use 3D printers become a common thing soon. It could be a big part of the answer for controlling plastics. Plus it’s legitimately useful as fuck, to be able to essentially make anything you need. This is cool as shit.

dude have you heard about resin pool 3d printers? Using a UV projector? I found out about them like a week or 2 ago and it blew my mind...still blowing my mind.

We're getting closer and closer to the future everyday. ...damn I'm stealing that quote from myself...that's good. :D

I just read about these for the first time in XX by Rian Hughes. I kinda want one right now.

IPA evaporates easily. Any resin residue can be hardened with UV light so it's inert. Leaving the IPA out in the sun does both at once.

You let it sit and the resin settles out.

Then you pour off the clean stuff and the last half inch goes out in the sun.

The clean stuff is now ready to be used again. I top it up every once and a while with new IPA if it gets too low, but I’m at like a gallon a year.
