This dataset was created as part of a student project and contains microCT data from additively manufactured tensile specimens with different lattice structures, images of the failure mechanisms, and other experimental data. Information on file structuring: The specimen designations can be found in the Excel table SampleDesignations.xlsx. Using this specimen designation, the measured values of the tensile test can be identified, as well as the microCT recordings of the specimens. Additionally, photos and videos of the failure mechanisms are provided (partially) unstructured. The material parameters are shown in MaterialProperties and an overview of the design space of the sample in SampleGeometry+LatticeDesignSpace.
