In this video I quickly recover isopropyl alcohol from resin 3D Printer wash in just 4 hours. Using methods similar to those used in water treatment plants. We add an aluminum sulfate solution to our 3D Printer IPA resin wash and mix until the resin particles coagulate and leave us with clear IPA. Once we have processed the resin wash we decant the isopropyl alcohol into another container for reuse on new resin 3D Prints. This method of isopropyl alcohol recycling is cheap and easy. 0:00 - Why recycling IPA is Hard 2:08 - IPA Recycling & Wastewater Treatment 4:01 - Aluminum Sulfate & Resin Wash Treatment 5:08 - IPA Recovery Process 6:32 - Tips for Wash Station Users 7:38 - Getting all your IPA Back 8:05 - IPA Dilution Concerns 8:37 - Aluminum Sulfate vs "Alum" 9:24 - Wrap Up Aluminum Sulfate - https://amzn.to/3woW0xU Glass Beakers - https://amzn.to/3o56NcW Magnetic Stirrer - https://amzn.to/3mUlMHm Wash and Cure Plus - https://amzn.to/3oa8PbP Spare Wash Container - https://amzn.to/3BXJXbP 99.9% Alcohol I Use - https://amzn.to/3BVDAWF Please mash that like button if you enjoyed this video and leave your comments below!
