Mechanical characterization of two-photon polymerization submicron features

Two-photon polymerization (TPP) is promising method for additively manufacturing nanoscale structures with complex geometries. For example, TPP has been used to fabricate very high strength-to-weight lattice structures that can be used in a variety of biomedical and aerospace applications. However, one of the major factors limiting TPP as a true manufacturing technique is the uncertainty in how printing parameters affect the mechanical properties of the materials produced at the voxel level. Therefore, the purpose of this thesis is to characterize the scale dependent effects of speed, power, and post curing methods on TPP resists. In order to achieve this purpose, a custom MEMS tensile tester was designed, fabricated, and calibrated for direct integration into the TPP process with resolution and range capable of measuring
