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 in situ monitoring system for volumetric additive manufacturing (VAM).
Background:
LLNL-s breakthrough Volumetric Additive Manufacturing (VAM) technology takes computed tomography (CT) “views” of 3D objects from multiple angles, and projects these images into a photosensitive resin. The resin cures at points where the accumulated, absorbed light energy exceeds the gel thresholds, and when the remaining liquid resin is drained, it produces 3D objects within seconds or minutes, much faster than traditional layer-by-layer 3D printing techniques. Since this revolutionary manufacturing process can 3D prints components in one step, real-time monitoring of the process is critical to increase reliability and to avoid product waste. Conventional monitoring relies on high refractive index or scattering property change of resin materials upon polymerization. However, for resins with low refractive index change, these conventional imaging methods fail due to low contrast. There is a need for imaging methods that can visualize VAM processes of low refractive index-changing materials.
Description:
A detailed non-proprietary overview of the technology/solution/innovation/expertise. Describe the invention. How does this invention address those gaps or improvements or what problem does it solve as discussed above?
The approach is to use quantitative phase imaging (QPI) using a common-path phase-shifting interferometry technique. A sequence of four phase shifts with an increment of π/2 between unscattered reference beam and scattered sample beam are imparted by a spatial light modulator. A quantitative phase image is retrieved fro... - Documents:
