3D nanoprinting addresses a critical research and development direction in additive manufacturing. We have investigated the technical challenges of high spatial precision in materials delivery, and of registry between components, physically and temporally. Our approach involves a combination of the scanning probe’s spatial precision and advanced local delivery methodologies, e.g. nanofluidics (Figure). Using star polymer materials based on polystyrene cores and dimethylamino-functionalized methacrylate arms, our results revealed how the molecules assemble from the nano- to the meso-scale. Unusual intermolecular behavior was observed during layer-by-layer nanoprinting at this nm-scale level. New physical insights will be presented from the 3D printing of various structures with designed functionalities. Potential applications will also be discussed during presentation.
