Isopropyl Alcohol IPA Alcohol
The most common alcohol used for washing resin 3D printed objects is isopropyl alcohol (IPA) and it’s chemical formula is C3H8O. Why? It’s simple to get just about anywhere and it has withstood the test of time. It comes in 3 different commercially available common strengths: 70%, 91%, and 99%.
IPA basically just breaks down uv printing resin, weaker resins are formulated so it can be broken down with water – which means that IPA works even better on that kind. 2 part resins is a chemical exothermic reaction and afterwards becomes inert after it cures and off gases.
IT dissolves liquid resin and is the most effective way to clean resin off everything. We use this to clean up the resin mess after all our workshops.
IPA can also be used to dissolve liquid resin. To clean and prepare 3D prints for curing, simply submerge the printed parts in a bath of IPA for about three minutes. If there are still traces of liquid resin left, you can repeat this rinse one more time
As the name implies, water-washable resin is a type of 3D printing resin that is soluble in water.
