Technical Overview

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.

Development Status

Current stage of technology development: 

TRL ☐ 0-2     ☒ 3-5     ☐ 5-9 

Advantages
  • 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
