| Abstract Scope |
Multi-photon lithography provides the possibility to design novel miniaturized testing structures that would be difficult or impossible to fabricate using conventional FIB based approaches. Furthermore, they enable statistically relevant assessments, in contrast to the typically rather scarce FIB based experiments. In this work we designed novel testing vehicles to assess local deformation and fracture properties of the printed polymers, as well as the adhesive properties of polymer/material interfaces. Geometrical designs were optimized to reduce printing artifacts and render the testing structures highly tolerant against misalignment. By combining machine learning enhanced high fidelity in situ experiments with high throughput ex situ nanomechanical testing, we assess the fundamental properties of the involved materials and interfaces, their dependence on printing parameters, as well as the impact of surface modification and material aging on the resultant mechanical properties. |
