We present a series of simple but novel nanopatterning methodologies inspired by traditional mechanical machining processes involving rolling, pullout, and forging. First, we introduce roll-to-roll nanopatterning, which adapts conventional rolling for continuous nanopatterning. Then, nano-inscribing and nano-channel lithography are demonstrated, whereby seamless nanogratings can be continuously pulled out, as in a pullout process. Finally, we discuss vibrational indentation micro- and nanopatterning. Similarly to the forging/indentation process, this technique employs high-frequency vertical vibration to indent periodic micro/nanogratings onto a horizontally fed substrate. We discuss the basic principles of each process, along with its advantages, disadvantages, and potential applications. Adopting mature and reliable traditional technologies for small-scale machining may allow continuous nanopatterning techniques to cope with scalable and low-cost nanomanufacturing in a more productive and trustworthy way.
