Siraya Tech Water Washable Resin

Siraya Tech Water Washable Resin has earned a loyal following among 3D printing hobbyists and professionals precisely because it eliminates one of the most tedious steps in resin printing: the isopropyl alcohol bath. Instead of soaking finished prints in IPA to strip away uncured resin residue, this formulation allows you to simply rinse parts under plain tap water, making post-processing faster, cheaper, and considerably less smelly. This water washable characteristic doesn't come at the expense of print quality either, as the resin still delivers the crisp detail and smooth surface finish that Siraya Tech has built its reputation on, making it suitable for miniatures, prototypes, and detailed models alike.

On the bench

Formulated for use with standard LCD and DLP resin printers, this resin cures reliably under typical 405nm light sources, meaning it slots into most existing workflows without requiring special equipment beyond what you'd already use for standard resins. The viscosity is manageable, pouring easily into vats and self-leveling without excessive bubbling, which helps reduce failed prints from air pockets or uneven layers. Colors are available in various pigmented options, and the cured parts exhibit decent toughness for a washable resin, striking a balance between the brittleness sometimes associated with easy-cleanup formulas and the durability printmakers expect from standard resins.

Living with it

Beyond convenience, Siraya Tech Water Washable Resin appeals to makers who print indoors or in spaces where ventilation for alcohol fumes is a concern, since the water-based cleanup process significantly cuts down on volatile organic compound exposure during post-processing. It's also a practical choice for anyone looking to reduce IPA consumption and disposal, which has both cost and environmental benefits over time. While it still requires proper curing under UV light after washing to achieve full hardness and dimensional stability, the overall workflow simplification has made this resin a go-to option for hobbyists prototyping frequently, as well as small studios producing detailed figures or functional parts who want to streamline their production pipeline without sacrificing the fine resolution resin printing is known for.
