- 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 UV photocurable, 3D printable silicone formulation with increased curing time and enhanced formulation shelf life. Background: Conventional manufacturing method for silicone-based products is injection molding, which limits the complexity of their designs; additive manufacturing (AM), however, is able to achieve more intricate geometries.� Presently, state-of-the-art silicone formulations for photocuring typically involve either incorporating a photo-protected Pt catalyst with reduced filler concentration or necessitate modifying silicone resin by introducing photocurable functional groups (such as acrylates or thiol-ene functionalities). Unfortunately, these alterations to the resin, while enabling AM, often result in compromised properties. To achieve high-performance photocurable silicones, a more straightforward approach is needed to enable 3D printing using unmodified readily available silicones that employ traditional Pt-catalyzed hydrosilylation chemistry for curing. Description: LLNL researchers have developed a novel photocurable silicone useful for producing three-dimensional objects via additive manufacturing. The resin formulations consist of a mult-component siloxane polymers with different functionalities, a platinum catalyst, a photoinitiator, and other organic peroxides.� The LLNL invention involves controlling the spatial and temporal aspects of the hydrosilylation reaction of silicones via the incorporation of additives which accelerate the photooxidation of photocuring silicones. This increase in reaction rate is crucial for additive manufacturing, enabling curing of a layer within 1 minute. Additionally, the resin formulation enhances the shelf life of silicone resins through novel addition of specific functionalities to the silicone polymers. The shelf life of the silicone resin can be extended from 6 hours to 1 week. The formulation is potentially suitable for stereolithography, two photon lithography, volumetric additive manufacturing and UV-coating applications. Related technology also available for licensing: https://ipo.llnl.gov/technologies/advanced-manufacturing/novel-siloxane-formulations-and-methods-3d-printable-silicones Advantages/Benefits:� Increased photocuring reaction rate enabling curing of a layer within 1 minute.� The shelf life of the silicone resin can be extended from 6 hours to 1 week. The formulation is potentially suitable for stereolithography, two photon lithography, volumetric additive manufacturing and UV-coating applications. Potential Applications:� The 3D printing of silicones has helped with the rapid development, prototyping and manufacturing of new emergency medical devices. It can also be beneficial towards manufacturing for surgical guides, medical instruments, and other implants, including dental devices and hearing aids. 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 UV photocurable, 3D printable silicone formulation with increased curing time and enhanced formulation shelf life 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 UV photocurable, 3D printable silicone formulation with increased curing time and enhanced formulation shelf life.
