The dissertation deals with the design and implementation of a methodology for indoor equipment using innovative technologies. The introductory part is devoted to the development of 2D and 3D CAD applications with attention to the use of parametric 3D CAD applications. Subsequently, the available technologies of 3D printing and mechanical testing of materials are described. The core of the thesis describes the analysis of custom production of 3D virtual devices, the design of the methodology of creating interior equipment, its creation in a selected 3D CAD application, simulation of virtual stress-strain analyzes and 3D printing of a prototype. The final part of the work is devoted to the verification of virtual simulations using mechanical tests.
