Is SLA resin skin safe?

Tough 1500 Resin is skin-safe according to relevant ISO 10993 testing and will continue to be supported on all Formlabs stereolithography (SLA) 3D printers, the Form 2, Form 3, Form 3B, Form 3L, and Form 3BL. This makes Tough 1500 Resin the first certified skin-safe material available on the Form 3 and Form 3L.

Is cured resin food safe 3D printing?

Is resin food safe? The answer is no. Substances may migrate from SLA parts which makes none of the resins and printed parts food safe by default. While some resins for dental and medical applications are certified biocompatible, that doesn’t mean that they’re food safe.
