Three-dimensional (3D) printing has become an active area of research and development (R&D) in additive manufacturing, due to its capability of producing 3D objects by design. Current 3D printing technology pushes the spatial limit to the micrometer scale.  Further miniaturization represents a major challenge.  This work reports new advances in miniaturizing 3D printing to the nanometer scale using scanning probe microscopy in conjunction with local material delivery. The concept of layer-by-layer nanoprinting by design has been demonstrated with various materials.  Nanometer precision is achieved in all three dimensions, as well as in inter-layer registry. The approach provides a new platform for performing experiments in designed 3D nano-environments, and enables production of new nanomaterials and scaffolds for photonics, devices, biomedicine and tissue engineering.<br/>
