As the next step after the topology optimization, the obtained optimized designs should be capable of being scaled up for manufacturing and uptaking into industrial practices. Despite recent advancements in the bottomup design engineering of the porous electrodes, the manufacturability and upscaling of the tailored designs have remained an issue, which is one of the prominent problems that most of the already developed models suffer from. Here, we propose for the first time a fabrication strategy by a combination of triply periodic minimal surface (TPMS) material design principles and non-uniform cellular structures. TPMS structures offer high volume specific surface areas and excellent mass transfer properties in electrochemical systems , two ideal properties for porous electrodes to increase the flow reactor performance. Inspired by previous primary usage of TPMS structures in electrochemical systems , we demonstrate for the first time a workflow to make TPMS-based electrodes from topology optimization output. The translation of the optimized design to high-resolution TPMS objects with guaranteed manufacturability is challenging, which is tackled using a state-of-the-art open-source computational geometry code in this study.
