TECHNOLOGY/BUSINESS OPPORTUNITY All Liquid Two-Photon Polymerization Resin Formulations Using Cationic Polymerization

The Lawrence Livermore National Laboratory (LLNL) is offering a technology/business opportunity for the development and commercialization of all liquid two-photon polymerization resin formulations using cationic polymerization. The technology has the potential to enable the fabrication of 3D structures with small feature sizes and large sample dimensions, which could be used in various applications such as battery, fuel cell, or electrolyzer electrodes, photonic or phononic crystals, mechanical metamaterials, microelectromechanical systems (MEMS), integrated circuit chips, quantum information processors, and microfluidic devices. The current stage of technology development is TRL 3-5. Companies interested in commercializing this technology should provide a statement of interest, including company name and address, point of contact, and a description of corporate expertise and/or facilities relevant to commercializing this technology. • The technology is a liquid two-photon polymerization (TPP) epoxy-based resin formulation capable of flowing under low load. • It enables tall, centimeter-scale parts to be built using conventional TPP objectives with high working distance lenses. • The unique photo-initiator chemistry helps to spatially control the extent of polymerization in the liquid resin, improving print resolution. • The technology has the potential to enable multi-wavelength TPP capabilities since cationic polymerizations are orthogonal to free radical acrylate polymerizations.
