 May 11, 2026 Kaiwen Hsiao, Texas A&M University [email] "PROGRAMMING MICRON- AND NANO-RESOLUTION POLYMER STRUCTURE AND PROPERTY WITH LIGHT" Summary: Kaiwen Hsiao presented her lab's work on programming micro and nano resolution polymer structures using light-based additive manufacturing. She discussed three research areas: developing a dual-wavelength nano-resolution DLP platform using photo-inhibitor chemistry, preserving self-assembled nanostructures within scalable 3D printing, and engineering tough elastomers through dual-cure bottle brush networks. She explained how these approaches address challenges in resolution control, transport properties, and thermomechanical performance for applications in microelectronics, batteries, and filtration. |

"PHOTOPOLYMER-BASED ADDITIVE MANUFACTURING OF METALS, CERAMICS, AND CARBON MATERIALS"
Summary: Max Saccone walked through various approaches for using printed polymer scaffolds as templates to synthesize inorganic materials — comparing heterogeneous powder-based resins, homogeneous single-phase resins, and liquid-liquid emulsion systems, and explaining the tradeoffs of each. Max then presented his lab's approach of infusing precursors into already-printed scaffolds after the fact, demonstrating this with metals, metal alloys, and carbon materials derived from polyacrylonitrile, showing results at the microscale with promising structural and compositional outcomes. The talk highlighted key remaining challenges, including process sensitivity, shrinkage during pyrolysis, and the difficulty of reliably polymerizing volatile monomers like acrylonitrile inside a printed scaffold without losing material.

“ONGOING EFFORTS IN VOLUMETRIC ADDITIVE MANUFACTURING AND COMPOSITE PRINTING USING MICROWAVES”
Summary: Johanna Schwartz presents her team's pioneering work on microwave-based volumetric additive manufacturing (VAM) — a 3D printing technique that cures entire objects at once rather than layer by layer. Unlike traditional light-based VAM, which is limited to transparent resins, her approach uses microwave irradiation to print with opaque, particle-loaded, and composite materials, opening the door to ceramics, carbon fiber composites, and beyond. Join her for a candid look at building a novel technology from the ground up, complete with early breakthroughs, ongoing challenges, and exciting future directions.
