Water-Washable Resin
Skip the IPA — rinse it in water.
A photopolymer formulated to clean up with plain water instead of isopropyl alcohol. Lowers the cost and hassle of post-processing for hobby SLA, at the cost of being a bit softer and more humidity-sensitive than standard resin.

— Print tips
What we'd tell a friend printing this.
- 1Rinse promptly in clean water, then UV cure 5–15 minutes
- 2Don't pour rinse water down the drain — cure the residue first
- 3Keep the bottle sealed; water-washable resin is hygroscopic
- 4Cure fully — under-cured parts stay tacky and weak
