The fabrication of free-shaped 3D objects with very high accuracy using focused electron beam-and focused ion beam-induced deposition (FEBID and FIBID) has been demonstrated in recent years.[1] For instcnce, we demonstrate the formation of free-form ferromagnetic 3D nanostructures and nanowires that can be used as functional devices and at the same time can emulate different morphologies in terms of magnetic properties.[2] <br/>Moreover, the direct writing also enables the growth of core-shell heterostructures by combination of 3D-nanowire FEBID scaffolds and the successive site-selective chemical vapor deposition (CVD). In particular, conductive 3D nanowire-based bridges are printed by FEBID and used as resistors allowing deposition induced by Joule heating. This hybrid-approach allows tailoring the cross section, shape and material combination for specific purposes. The applicability of the nano-CVD onto FEBID-nanowires has been demonstrated for two material systems of specific physical properties.[3] The fabrication of complex 3D core-shell heterostructures promises to add new functionalities by combining free-shaped 3D nanostructure writing with thin film deposition of different functional materials.<br/> <br/><br/><i>References:</i><br/>[1] <i>J.
