- Description
- 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 electrical resistance diagnostic tool. Background: LLNL researchers developed intelligent feed forward (IFF) to accelerate the qualification and certification of additively manufactured parts during the laser powder bed fusion (LPBF) process; their ultimate goal is that once fabricated parts are completed, they could be used straight away without further testing.� Parameters of interest during the printing process include those for quantifying pore formations, spatter, local area temperature, liquid flow in the melt pool and other physical phenomena.� There is an outstanding need for cheap, scalable diagnostic tools for in-process inspection and flaw mitigation.� This invention describes one of these tools for monitoring electrical resistance. Description: Electrodes that measure current and voltage are connected to the LPBF build plate by magnetic metal arms.� These arms are placed on a steel weighted base that provides a high degree of mechanical flexibility to conform to small geometries and can be easily incorporated into a complex manufacturing system.� Furthermore, the electrodes are connected to tapered copper tips that can provide strong electrical connection to allow high current over a uniform area.� Using these electrodes, electrical resistance is measured; gaps in electrical conductivity in the printed parts would be indicative of possible cracks or voids in the printed part. Advantages/Benefits:� Value proposition:� Real-time in-situ monitoring of 3D printing process that reduces manufacturing costs. Potential Applications:� Laser powder bed fusion Metal additive manufacturing Electrical resistance tomography Conductivity monitoring In-situ diagnostics Development Status:� Current stage of technology development:� TRL 3 LLNL has filed for patent protection on this invention. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.� Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note:� THIS IS NOT A PROCUREMENT.� Companies interested in commercializing LLNL's electrical resistance diagnostic tool should provide an electronic OR written statement of interest, which includes the following: Company Name and address. The name, address, and telephone number of a point of contact. A description of corporate expertise and/or facilities relevant to commercializing this technology. Please provide a complete electronic OR written statement to ensure consideration of your interest in LLNL's electrical resistance diagnostic tool. The subject heading in an email response should include the Notice ID and/or the title of LLNL�s Technology/Business Opportunity and directed to the Primary and Secondary Point of Contacts listed below. Written responses should be directed to: Lawrence Livermore National Laboratory Innovation and Partnerships Office P.O. Box 808, L-779 Livermore, CA� 94551-0808 Attention:�� IL-13904
