Additive manufacturing, also widely referred to as 3D printing, is an emerging and innovative manufacturing process that differs fundamentally from conventional manufacturing processes. In research and industry, it opens up completely new possibilities for scientists. 3D printing using two-photon polymerization is one of the photopolymerization processes, whereby extremely small components can be produced. In this work, two-photon polymerization is used to produce nanoscale deformation structures as well as nanocomposite materials. The deformation structures show very good deformation behavior and offer the possibility of testing a large number of samples in a short time. Other processes, such as pyrolysis, were used in the successful production of composite materials. The work shows that two-photon polymerization is an ideal tool for producing defined model systems.
