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).

This resource includes files in .obj and .npy formats.
