Recycling & Reusing Resin Saturated IPA | Resin 3D Printing #1

Washing resin prints is a required post processing step in Resin printing but the washing solvent or solution doesn’t last forever and will eventually need to be replaced which can easily get expensive especially for a small business.
So in this video I’m going to explain how I recycle my 99.9% IPA after it has been saturated in resin from all the washes. 99.9% IPA washes resin great but is quite expensive so simply replacing it every time it gets saturated is not only expensive but wasteful.
Recycling & reusing your washing solvent such as my IPA is a great way to not only save money in an expensive hobby like resin printing but also helps out the environment as well!
The steps to recycle IPA is surprisingly easy & effective but isn’t always done because of the mess it can make as well as how tedious or time consuming it can be just to do.
(WARNING)
IPA and other resin washing solvents can emit fumes which can be an irritant so be sure you are wearing proper PPE in the form of eye protection & a respirator while performing this recycling process.
The solvents being recycled are flammable & the vapors emitted are even more so thus great care needs to be taken into consideration before & while attempting this process.

OMG. Why has no one else recommended and explained this as well as you have. Thanks very much.

Wow - someone who can communicate clearly and succinctly! Perfect vid, perfectly simple. Kudos!

I don't owned any 3d printer yet, but this is one channel that explains every details that is not covered by many youtuber...

We need wash and cure stations that recycle their IPA. The entire wash process needs to be optimized for best results with minimal labor and minimum alcohol consumption. I spray the parts and build plate with IPA straight out of the printer and the IPA runoff from that is heavily contaminated with resin so it goes into a tray that is exposed to UV to cure it so the resin can be discarded. Then I do an agitated dunk into the "dirty" IPA tank followed by an agitated dunk in the "clean" IPA tank, and the parts are then sprayed again with new IPA to remove the last of the contaminates from the "clean" tank. That IPA drains into the clean tank. We need wash and cure stations that swirl and cure IPA, then filter the IPA with a large and inexpensive bypass filter media and/or centrifuge.

Great video, i've tried this in the past with little success. but now i have the same wash and cure station i'll have another attempt at it

What do you do with the goo? It's microplastics. How do you safely dispose of it and keep it from getting into the environment?

[@JoshuaRilliet]

Merci pour cette méthode de recyclage qui me semble très efficace et que je testerais prochainement ;o)

[@Submanca]

Just followed this word for word and it worked great but I don`t think I will blend it up next time. If I carefully take the top cured resin off I can save many hours of the IPA settleing.

Have u vacuum filtered it? Im waitiing for that content

[@EhOThomas]

Tried and didnt work. The mix just became a white gello. How long you let the light curing it?

[@David-ey9jg]

Anyone know if there is a flocculant for this?

[@RexAnothership]

Does anyone know if this would work with TPM?

Hello. I am a bit new to 3D printing. You mentioned that you have a pre and post IPA solutions. How would this be implemented in the cleaning process? Print > Pre Wash > Remove Supports > Post Wash?

[@MinWin3D]

So how I do it is: 1) Print 2) Remove supports 3) Pre-wash to remove the bulk of excess resin 4) Post-wash to remove residual resin still on print Reason for the 2 washes is because you won’t get a good wash with saturated IPA as it will leave a film of slick residue on the print. The post-wash is not as dirty so it will be able to clean the resin off more effectively & due to the reduced amount of resin on the part it won’t get dirty as quickly.

[@bswordsman4320]

@@MinWin3D Good to know. I will do this for my prints. Thank you for the info!

thanks for not making a whole documentary and getting to the point

Please add something about safety having the UV light on can be extremely dangerous for your eyes and skin which you haven't noted at all. With this video you're not noting that this is a non-standard use of the UV light so the person using it isn't getting the protection of the UV shield.
