Continuously fabricated 3D structures via projection printing process (IMAGE)
Caption
a. Optical image of a millimeter scale cube composed of 42 × 42 × 42 units of a metamaterial-like structure. Cube was fabricated in 2.3 hours, with a volumetric print rate of 1.08 × 10⁻³ mm⁻³ s⁻¹. b. An array of hemispheres with smooth curved surfaces. c. Micropillars with stress-induced curvatures fabricated using a grayscale imaging process. Percentages indicate grayscale level of half of the pillar. d. Trefoil knot showing 3D structuring capabilities.
