Abstract: Custom-form batteries can supply complex, practical systems with an optimal energy density that wouldn't otherwise be possible using traditional battery form-factors. For example, iron disulfide (FeS2) is a prominent conversion cathode of commercial interest. 3D direct-ink write (DIW) printing of FeS2 inks can be used to produce ridged cathodes from the filamentary extrusion of highly concentrated FeS2 inks (60-70% solids). These ridged cathodes exhibit optimal power, uniformity, and stability when cycled at higher rates (in excess of C/10). Meanwhile, functional cells with custom-form wave-shaped electrodes (e.g., printed FeS2 cathodes and pressed lithium anodes) exhibit improved performance over similar cells in planar configurations. In general, the DIW of concentrated inks is a viable path toward the making of custom-form conversion lithium batteries. More broadly, ridging is found to optimize rate capability.

Abstract: Direct ink write (DIW) printing of reactive resins presents a unique challenge due to the time-dependent nature of the rheological and chemical properties of the ink. As a result, careful print optimization or process control is important to obtain consistent, high quality prints. The present invention uses a flow-through characterization cell for in situ chemical monitoring of a resin ink during DIW printing. Additionally, in-line extrusion force monitoring can be combined with off-line post inspection using machine vision. By combining in-line spectroscopy and force monitoring, it is possible to follow reaction kinetics (for example, curing of a reactive resin) and viscosity changes during printing, which can be used for a closed-loop process control. Additionally, the capability of machine vision to automatically identify and quantify print artifacts can be incorporated on the printing line to enable real-time, AI-assisted quality control of the printed products.

Abstract: A novel method can determine the mechanical properties of additively manufactured structures using artificial neural network and computer vision models. Using this methodology, simulation times can be dramatically reduced, allowing for the implementation of a genetic algorithm which can determine the optimal AM parameters to achieve a targeted mechanical response.

Abstract: The invention is directed to the selective dual wavelength olefin metathesis polymerization for additive manufacturing. Dual-wavelength stereolithographic printing uses ring-opening metathesis polymerization of the metathesis-active polymers. As an example, a resin formulation based on dicyclopentadiene was produced using a photolatent olefin metathesis catalyst, various photosensitizers and photobase generators to achieve efficient initiation by light at one wavelength (e.g., blue) and fast catalyst decomposition and polymerization deactivation by light at a second wavelength (e.g., ultraviolet). This process enables 2-dimensional stereolithographic printing, either using photomasks or with patterned, collimated light. Importantly, the same process was readily adapted for 3-dimensional continuous additive manufacturing, with printing rates of up to 36 mm h?1 for patterned light and up to 180 mm h?1 using un-patterned, high intensity light.

Abstract: Metal hydride nanoparticle inks provide an alternative to traditional metal inks. Metal hydride nanoinks can be printed by aerosol jet printing and cured at elevated temperatures to provide conductive patterns. As an example, printed patterns of titanium hydride nanoink on polyimide and cured by pulsed photonic curing were found to exhibit electrical conductivity, with a sheet resistance on the order of ˜150 ?/?.

Abstract: An array of airfoil-shaped micro-mixers that enhances fluid mixing within permeable membrane channels, such as used in reverse-osmosis filtration units, while minimizing additional pressure drop. The enhanced mixing reduces fouling of the membrane surfaces. The airfoil-shaped micro-mixer can also be coated with or comprised of biofouling-resistant (biocidal/germicidal) ingredients.
