Fig. 3: Illustration of a printed structure with varying internal cavity diameters.
From: Thin-film DLP 3D printing of multi-material parts with closed-cell internal voids
a A 3D model incorporating enclosed cavities ranging from 10 mm to 0.5 mm in diameter, alongside a corresponding CT-scan reconstruction of the 3D printed model. b Comparison between the theoretical (designed) cavity diameters and the actual average diameters measured via CT scanning. c Absolute value error of printed diameters from the desired diameters for different internal cavity sizes. Inter-layer solvent washing was not used for these prints, yet the error remains low and highly consistent (sub-one-layer variation) between different cavity sizes.
