Contract Opportunity

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 electromagnet-SLA printer.

Background:

Liquid crystal elastomers (LCEs) are “smart” materials that have the ability to change their shape or orientation in response to external stimuli such as temperature, light, or mechanical stress. This unique combination of properties makes LCEs suitable for a wide range of applications in diverse industries including aerospace, automotive, electronics, and biomedical. Manufacturing LCEs requires the ability to magnetically manufacture complex structures with programmable material alignment in 3D space.

Description:

This LLNL invention is capable of generating, on-the-fly, tunable magnetic field strengths with voxel-by-voxel alignment. The approach is to use a custom designed Halbach array consisting of permanent magnets or electromagnets to provide a uniform magnetic field in any direction. This Halbach array will then be coupled with a stereolithography (SLA) printer so that locally aligned regions can be “locked into” place by curing during 3D printing. A key feature of this invention is the ability to generate relatively large magnetic field strengths (

Advantages/Benefits:

• Value Proposition: Increased performance to enable a bigger market


• Tunable magnetic field strength


• Varying directions of magnetic field

Potential Applications:

• Reversible and repeatable 3D-to-3D shape change


• Tunable stiffness architectures


• Cellular fluidics


• Light-weight, high-strength applications

Development Status:

Current stage of technology development: TRL 3
