| Abstract Scope |
Inkjet printing is a leading technique for fabricating additively manufactured electronics (AME) due to its design flexibility, high resolution, and scalability. Most commercial AME inkjet systems co-deposit a conductive silver ink and a single photo-curable polymer dielectric ink to build electronic components layer-by-layer. A main limitation is the brittleness of the polymer materials. To address this, we investigate co-jetting two polymer systems to form interpenetrating polymer networks (IPNs), which can achieve superior mechanical and thermal properties over individual polymers. Most commercial inkjet systems have closed hardware and software, limiting such experiments. This presentation focuses on developing a custom multi-material inkjet printing platform designed to facilitate the engineering of multiscale heterogeneity with IPNs. Main topics include printer design and implementation, printing strategies for multiscale heterogeneity, and exploring process parameters to optimize droplet spacing, line widths, and ink spreading/mixing. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
