The presented master’s thesis deals with the issues of measurement and quality assessment of components produced using 3D printing technologies, specifically focusing on the FDM/FFF method in the field of prototyping and small-batch production. The aim of the thesis is to analyse current trends in additive manufacturing and to design a functional system for monitoring the mechanical properties of prints through tensile testing using a prototype of a custom testing device, enabling immediate validation of components directly at the production site. Within the framework of the work, a measurement methodology is developed utilizing miniature specimens and non-contact deformation sensing via an optical extensometer. The thesis includes practical testing of the proposed procedure on PLA and PETG materials, an analysis of the influence of print anisotropy on the resulting material characteristics, and a techno-economic evaluation of the return on investment in measurement technology within a corporate environment. The outputs of the work suggest the potential of the proposed system for the effective determination of material behaviour and the possibility of increasing the reliability of additively manufactured printed parts in technical practice.
