Polyjet is an additive jetting process utilizing liquid photopolymers deposited in droplets and then cured with a UV light source layer by layer. Parts made with Polyjet are highly accurate with great surface finish. Objet parts are used for form and fit checking, limited mechanical use, master patterns for cast urethane or for cosmetic models when sanded and painted.
CAVEATS: Polyjet parts are not as strong as SLA, FDM or SLS. They are prone to warpage due to moisture and heat.
