The study explored the macrostructure and manufacturability of additively manufactured 316L metal lattice structures with micro computed tomography and the possibilities of open source software in data analysis. Samples described and reported in Puttonen, T., 2020, November. Evaluation of Metal Lattice Structures With X-Ray Micro-Computed Tomography: Dimensional Accuracy and Manufacturability.
