TECHNOLOGY/BUSINESS OPPORTUNITY Flow-based Volumetric Additive Manufacturing System

Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Flow-based Volumetric Additive Manufacturing System.

Background: Volumetric Additive Manufacturing (VAM) is an emerging technology in near-instant 3D printing where the part is formed in free space without imposed stress. Currently, containers that hold the resin must be replaced between prints. This is manual and time-consuming, which precludes the method to scaling for high throughput applications.

Description: LLNL researchers have developed an approach to incorporate flow (either in stop-flow or continuous flow operation) to replace resin in the vial to enable high throughput production of 3D printed parts with VAM.

Advantages/Benefits: • VAM is already one of the most competitive VAT photopolymerization methods for speed, this implement unlocks even faster rates - opens a path towards 100x mfg rate • Continuous printing - does not require manual operation to swap out resin containers after print is completed Potential Applications: • Fast, accurate, repeatable high-throughput production of 3D printed parts with arbitrary geometries Development Status: Current stage of technology development: TRL ? 0-2 ? 3-5 ?
