Nanoforging – Innovation in three-dimensional processing and shaping of nanoscaled structures

Abstract

Summary Background: This paper describes the shaping of freestanding objects out of metallic structures in the nano- and submicron size. The technique used, called nanoforging, is very similar to the macroscopic forging process. Results: With spring actuated tools produced by focused ion beam milling, controlled forging is demonstrated. With only three steps, a conical bar stock is transformed to a flat- and semicircular bent bar stock. Conclusion: Compared with other forming techniques in the reduced scale, nanoforging represents a beneficial approach in forming freestanding metallic structures, due to its simplicity, and supplements other forming techniques.

Engineering manipulation at nanoscale: further functional specifications

“…Nanoforging requires the use of strong material (micro-hammer) for shaping the subject material. Landefeld and Rösler (2014) presented a forging tool that has the ability of trimming, forging and bending. Cleaning needs a compressed air nozzle to allow nondestructive removal of unwanted particles.…”
