Abstract

Due to its high feature resolution and the capability to produce 3D-structures without the need of support-structures, two-photon polymerization (2PP) is one of the fastest growing technologies in the field of additive manufacturing. To ensure good quality of the fabricated parts, proper methods for evaluating the suitability of different material systems for 2PP are necessary. In this paper, we present a fast screening method based on measuring the Youngs modulus of micro-cantilevers giving a quantifiable measure and representing the material- and fabrication-properties in one experiment.
