Výzkum vlivu dokončovacích operací na modifikaci užitných vlastností součástí vyrobených aditivní technologií

Abstract

This dissertation deals with advanced research in additive manufacturing, namely 3D metal printing using SLM technology. The main objective of the dissertation is to determine the behavior of printed components following the finishing operations and to make this technology more useful. In the course of solving the work there were also secondary targets that give a very good image and a more advanced introduction to the problems of metal printing. These secondary objectives also lead to the improvement of the subsequent teaching of additive production at the Department of Machining, Assembly and Engineering Metrology, Faculty of Mechanical Engineering, University of Mining Technical University in Ostrava. The work is divided into four main blocks. The first block is a comprehensive review of the current state of knowledge in terms of print parameters, residual stresses and finishing operations. Only the experimental activities that cover the research of AISI 316L (W. Nr. 1.4404) stainless steel printing are dedicated to the remaining three blocks. At the end of the work the results obtained and the benefits are stated. Part of the results obtained has already been published at professional conferences and concrete findings will be used to improve the quality of production using 3D metal printing in practice. The results will be further developed and published.
