A laborious study was carried out on specimens made with the help of the Prusa 3D printer, having different densities, from PLA and PETG materials, which were subjected to bending, thus obtaining the mechanical properties, namely stiffness, flexural rigidity, maximum bending strain, Young’s modulus, and maximum bending stress. This method of printing objects facilitates the obtaining of objects with high properties, which can replace important components within some structures of medical devices or mechanical components. In this paper, we will analyze the conclusions between the minimum and maximum values that we obtained.

A laborious study was carried out on specimens made with the help of the Prusa 3D printer, having different densities, from PLA and PETG materials, which were subjected to bending, thus obtaining the mechanical properties, namely stiffness, flexural rigidity, maximum bending strain, Young’s modulus, and maximum bending stress. This method of printing objects facilitates the obtaining of objects with high properties, which can replace important components within some structures of medical devices or mechanical components. In this paper, we will analyze the conclusions between the minimum and maximum values that we obtained.
