“…Additive manufacturing and direct-write processes have experienced significant growth in the past decade, where new materials, techniques, and applications have all emerged. Various size scales have been explored historically, but recent pushes have extended three-dimensional additive manufacturing toward the micro- and nano-scale. , While several techniques like direct-ink writing, , multi-photon lithography, , electrohydrodynamic printing, dip-pen lithography, laser induction, − and other methods in principle work in the sub-micron regime, focused electron and ion beam-induced deposition (FEBID/FIBID) is likely the most developed technique for synthesizing complex architectures in three dimensions. Several applications have been demonstrated, including nanomechanical resonating sensors, , advanced scanning probe tips, chiral plasmonics, plasmonic split ring resonators, and magnetic architectures …”
