Nanostructured Free-Form Objects via a Synergy of 3D Printing and Thermal Nanoimprinting.

ABSTRACT: High-resolution surface patterning has garnered interests as a nonchemical-based surface engineering approach for creating functional surfaces. Applications in consumer products, parts for transportation vehicles, optics, and biomedical technologies demand topographic patterning on 3D net shape objects. Through a hybrid approach, high-resolution surface texture is incorporated onto 3D-printed polymers via direct thermal nanoimprinting process. The synergy of geometry design freedom in 3D printing and the high spatial resolution in nanoimprinting is demonstrated to be a versatile fabrication of high-fidelity surface pattern (from 2 µm to 200 nm resolution) on convex, concave semicylindrical, and hemispherical objects spanning a range of surface curvatures. The novel hybrid fabrication is fu
