SAMPLE-CERTIFICATE FOR THE INVESTIGATION OF THE THREE-DIMENSIONAL DETAIL MADE BY THE METHOD OF SELECTIVE LASER MELTING

摘要

The utility model relates to the field of manufacturing of three-dimensional products from metal powders by the method of selective laser melting. The objective and technical result of the utility model is the creation of a three-dimensional sample-witness, which after its manufacture by the method of selective laser melting provides an opportunity to investigate the quality of the metal of its elements having different geometric dimensions of the elements and their spatial position, to optimize the parameters of the manufacturing method. The technical result is achieved by the fact that the witness sample for optimizing the technological parameters of the process of manufacturing articles of complex shape by the selective laser melting method is made in the form of a three-dimensional spatial structure comprising at least four sheets, made in the form of a wave profile and placed at an equal distance from each other, which are interconnected by bars of square section, arranged in rows. 1 of Fig.
