Chemical Resistant Polyjet Material?

[patreojames]

Hello all,

I am printing with an Objet30 Pro and noticed that if the parts soak in Purell, they become soft and expand. Does anyone know how I can make the part chemical resistant?

I know Stratasys recommends Epoxy, but the parts I am working with have small features that are easily clogged with epoxy or other thick coatings.

Thank you!

Nothing you can do. If the material itself isnt chem resistant enough then the only work around is to coat it. Epoxies are usually quite chem resistant once cured. You can get a thinner viscosity one but the thicker the coating the better the barrier it will make over the print material. Try west system epoxy. Its a thinner laminating epoxy
