3D printing on the macroscale is a huge trend worldwide. Ultimately, one would like to 3D print anything, including complete functional devices. Apart from boosting printing speed and pushing spatial resolution to the nanometer scale, 3D printing of many different materials poses a major challenge. In 2D graphical printers, thousands of different colors can be printed from just three color cartridges. By analogy, future 3D printers may print thousands of effective (meta-)materials from just a few materials cartridges. These metamaterials should not only be tailored in terms of their optical properties, but also electrical, magnetic, thermodynamic, mechanical, and bio-chemical.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
