Abstract
Using data from tensile tests, this study aims to characterize and analyze the behavior of a test body with internal structure in three different formats, honeycomb, diamond and cross, obtained from the melting and deposition process known as 3d printing. The test specimens used in this study follow the ASTM D638-14 standard, as well as the other parameters necessary to perform tensile tests. The specimens were printed with ABS, acrylonitrile butadiene styrene, on a 3D Systems CubePro 3d printer. The tensile tests were performed on a Shimadzu® mechanical testing machine. At the end of the tests sufficient data were obtained to measure the Young's modulus, tensile strength limit, rupture limit, yield strength, maximum displacement of the test specimen and the density for the three different internal structure formats.
