Additive Manufacturing of Thermoset Polymers Using Projection-based Stereolithography

Storagenergy Technologies Inc. proposes a novel methodology that allows for the 3D printing of different wholly thermally cured thermosets in a fast and precise fashion mask-image-projection-based -Stereolithography (MIP-SLA) additive manufacturing process. The proposed MIP-SLA based approach has several advantages over other technologies for additive manufacturing of thermoset polymers, including 1) High feature resolution and structure complexity; 2) Fast fabrication speed; 3) Fine part fabrication; 4) No post thermal or other processing is required; 5) Controllability to print and render parts that range from elastomeric to glassy; and 6)        Capability to co-print two or more different thermally-activated thermosets.
