TUT 4: Nanofabrication and 3D Printing with Submicron Resolution (joint session CPP/TUT)

TUT 4.1: Tutorium

3D laser nanoprinting — •Martin Wegener — Institute of Applied Physics and Institute of Nanotechnology, Karlsruhe Institute of Technology, 76128 Karlsruhe, Germany

This tutorial follows a recently published review and perspectives article on 3D laser nanoprinting (V. Hahn et al., Opt. Photon. News 30(10), 28-35 (2019)).

I will review the underlying physical principles, describe the state-of-the art in the context of many other alternative 3D additive manufacturing approaches, and emphasize two challenges: (i) Substantially faster and scalable 3D printing with sub-micrometer voxel sizes, and (ii) multi-material 3D nanoprinting.

(i) I will present (unpublished) results on rapid multi-focus 3D laser nanoprinting leading to printing rates around 10^7 voxels/s at sub-micrometer voxels sizes. For example, this has led to 3D mechanical metamaterials with more than 100 thousand unit cells and more than 300 billion voxels total. Furthermore, I will sketch our ideas to go well beyond this by introducing light-sheet 3D laser nanoprinting.

(ii) I will discuss three different approaches towards multi-material architectures: (a) integrated microfluidic chamber, (b) stimuli-assisted 3D laser nanoprinting, and (c) meta-inks.
