Effects of structural processing settings on the surface morphologic profiles of prepared hollow conic 3D micropore structures. (a) Schematic slicing (left) and hatching (right) patterns for the DLW-TPP process of hollow 3D microstructures. The slicing and hatching parameter settings are realized by the DeScribe software. (b) Surface morphologic properties of the hollow 3D microstructures prepared using different-sized constituent units. Scale bar: 2 μm, apply to all SEM images. (c) Surface roughness of the hollow 3D microstructures vs structural processing conditions (left axis, black curve). The width of the cracks formed on the surface of hollow 3D microstructures vs structural processing conditions (right axis, blue curve). (d) Minimum required processing time for the fabrication of hollow 3D microstructures vs structural processing conditions.
