This data-set was collected as part of the experimental characterization of 3d-printed Polylactic acid (PLA) lattice structures. The dataset is stored as three Excel spreadsheets .xlsx, one for each load case: compressive, tension A type, and tension B type. The dataset consists of the measurements taken by an MTS Bionix 370 testing machine in a compressive and tensile load of different lattice structures, architecture, and density. Each spreadsheet name codes the type, density value, and replica number of the specimen being tested with the following code: INFILL TYPE LETTER (H, T OR S) -DENSITY VALUE (As a percentage) - Replicate identification. e.i H65C represents the specimen "c" of a hexagonal infill with 65% density. In each experimental point, the complete timed values of the sensors were recorded: force, displacement, time, and the extensometer displacement measurement. The calculated variables such as stress and strain are also shown based on the specimen dimensions available in each sheet. This dataset is part of research on the mechanical properties of different infill lattices and will be published in the journal article "Tensile and compressive behavior of additive manufacturing polylactic acid lattice infill patterns".
