Scientists at Perm National Research Polytechnic University (PNRPU) have significantly improved technical control methods for checking the quality of parts created on 3D printers, especially in industries such as metallurgy and mining. This is particularly important for the production of complex and highly loaded structures.
Traditional control methods for such products may be ineffective due to the peculiarities of additive technologies, where parts are created layer by layer, which can lead to material inhomogeneity and the appearance of microcracks or other defects. To solve the problem, PNRPU scientists have developed an expanded set of experiments that allows for more accurate identification of weak points and assessment of the strength characteristics of 3D products.
The research includes tensile, torsional, and other types of mechanical stress tests, which help assess how changes in layer orientation during 3D printing affect the behavior of the material under real operating loads. The data obtained will help improve the prediction of the properties of 3D products and improve the quality of manufactured products, especially in critical industries such as metallurgy and mining.
Such developments will reduce the risk of breakdowns and increase the service life of additive parts, which in turn will make equipment produced using 3D printing more reliable and safe for use in industry.
