Abstract :

It has become routine to print out any text or any c olor graphics within seconds upon the push of a button by using tabletop 2D printers. By analogy, tabl etop 3D printers might someday allow to obtain any material, device, or system upon the push of a b utton. On the macroscale, 3D printing – or, more generally, 3D Additive Manufacturing – is already a  worldwide megatrend. In this talk, I will give an introduction into laser based 3D printing on the micro - and nanoscale and describe the state-of-the-art. I will emphasize the challenges of achieving finer fe atures below the diffraction barrier, of obtaining scalable and faster 3D printing, and of 3D printing  multicomponent micro- and nano-architectures, including active structures. Application example s include diverse micro-optical components, metamaterials, scaffolds for biological cell culture, an d 3D security features.
