“…It has been observed that the vibrations of the system in the first and second modes are high. Thanks to the revisions made, these values were improved and the system was developed [10]. Another of the issues examined in relation to vibration in the additive manufacturing method is the state of the nozzle and its positioning.…”

3D printers are widely used in every industry these days. However, the features required from the products are becoming more and more important. Especially in the field of prototyping, 3D printers have become indispensable in design and manufacturing. One of the most important factors determining the product quality is the surface quality. Also, the most important factor determining the surface quality in production is the robustness of the production machine. Therefore, a 3D printer with a Cartesian system, which is the most widely used mechanical system, was chosen in this study. A production sample in the shape of a cube was preferred and a total of nine different parameters were used at three different printing speeds (40, 60, 80 mm/sec.) and three different filling forms (hilbert curve, octagram spiral, concentric). The standard system vibrations of this printer were recorded with the help of dataloggers that measure 3-axis acceleration during production. Afterwards, mechanical improvements were made in the system in all 3 axes. After these improvements, the same production process was carried out again and the difference in mechanical vibrations in the system was examined. In addition, in order to observe the change in the production quality, the surface roughness values in each production were examined in 3 axes and the changes in the production quality were examined. Mechanical improvements provide quality increase in every axis on the surface quality. However, when compared with the measured vibration values, there is no significant correlation between them. As a result, it can be said that the rigidity feature in 3D printer mechanical system has a great effect on the product properties and quality.

The modelling of strain-induced martensite formation is simulated in advanced medium-Mn steel. The fraction of retained austenite (8%) embedded in the bainitic matrix is transforming into the strain-induced martensite during progressive static tensile tests. The originally elaborated technique and algorithms (using C++ language) are presented. The finite element method and LS-DYNA (LSTC Company, USA) have been deployed. The calculations of the stress-induced martensite start temperature were performed to characterize the austenite stability. The structural investigations using the SEM and EBSD have been conducted. The comparison of the experimental and numerical results has been made in terms of mechanical austenite stability.
