Industrial use of High-Precision 3D Printing via two-photon absorption (TPA) requires high structure homogeneity at a reproducible level. Although still mainly used in academia, the interest for industrial application is continuously increasing. For this purpose, a novel fabrication strategy for scalable fabrication will be presented. Additionally, reproducibility in structure formation will be analyzed for selected elements with respect to overall size, angle generation and lens characteristics. The results demonstrate both scalable processes and high reproducibility provided by a stable process during fabrication.

of polymerization via two-photon absorption (TPA), also known as High-Precision
3D Printing, is gaining increasing attraction. Since TPA is a scanning
technology, industrial throughput fabrication can be achieved either by
intelligent fabrication strategies and an excellent material basis, but also by
multi-spot exposure strategies. Massive parallelization is demonstrated, which
was realized by beam splitting diffractive optical elements (DOE). Simultaneous
fabrication with more than 100 focal spots will be reported. With this
approach, micro- and nanostructures are fabricated and application
possibilities for metaoptics will be illustrated. Important aspects like scan
speed and laser power will be addressed.
