Design and fabrication
Computer-Aided Design (CAD) was applied to design Schoen gyroid structures using Autodesk (USA) Fusion 360, generating Standard Tessellation Language (STL) files. A Solflex 350 Digital Light Processing Printer (W2P Engineering, Austria) was used for fabrication of each methacrylate-based gyroid (with 50% designed bed porosity) at specified feature sizes of 500 µm, 300 µm and 200 µm. All parts were printed with 50 µm layer thickness. Porogens were removed post-printing to create a nanoscale porous substructure .
