Physically simulated x-ray CT data of additively manufactured octet lattice structures with common defects. In Lawrence Livermore National Laboratory (LLNL) Open Data Initiative

The datasets are simulations, containing input and output models of x-ray CT simulations showing additively manufactured lattice structures with common defects. There are in total seven datasets, each one has an input file (CAD triangle mesh model in *.obj format) and an output file (a 3D numpy array, in *.npy format, where each value corresponds to an x-ray CT density value). The input files were created using Blender (https://www.blender.org/), and five defects were manually inserted (bent strut, broken strut, missing strut, thin strut, dross defect). The output files are simulations created using LTT (https://ipo.llnl.gov/technologies/it-and-communications/livermore-tomography-tools-ltt).
