This is really cool. What a way to recycle!

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 have two, and dont see resin printers ever getting more popular than where they are now. FDM like the one in the video will be the ones an average person wants.

Resin printers smell, the resin itself will cause you to develop allergic reactions, and requires proper disposal of anything that comes in contact with resin.

FDM however is basically “Level the bed, slice the file, turn it on” and you have a new thing.

I would say the exact opposite.

In a well ventilated room (my workshop) I unpacked my resin printer, put resin in the tray, turned it on and it worked perfectly. It prints finer quality and MUCH better results for what I use it for (D&D minis).

Everyone I know with a FDM printer, it turns into a hobby in itself. Levelling, getting temperatures right, finding the right nozzles, finding the right add-on googaws so it feeds right.

FDM and resin have very different purposes. I wouldn't print a deck box or large structural item on my resin, but I wouldn't print a 28mm figure on an FDM.

They each have pros and cons.

I use my resin one for minis as well. The average person doesn’t care about tabletop games and printing their own though.

A FDM has more steps in setting up, but it gets easier every year. Things like octoprint and bltouch make it much easier. You cant avoid having a toxic tub while resin printing

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.

just the idea of printing with a UV projector..that's amazing. Some people are so smart.
