3D printing quality evaluation using optical digitization
Schäffer, Matúš ; Vespalec, Arnošt (referee) ; Paloušek, David (advisor)
This thesis focuses on description of selected differences in printing strategy and functionality of proprietary and commercial slicer. These are tested by specially created experiments using the same FDM table printer and filament. 3D optic digitisation is employed to support accurate measuring of individual experiments. Then 3D scans are examined in inspection software which allows to attain the figures describing dimension and geometry accuracy. Subsequently, the results are analysed and the conclusion is defined.

Process Parameters Development for Producing of Lattice Structures Using 3D Metal Printing
Moravčik, Jaroslav ; Koutný, Daniel (referee) ; Vrána, Radek (advisor)
Selective laser melting (SLM) belongs to additive technologies. Progressive adding of layers of material powder and creating the structure with laser beam allows to create components with complex shapes, for example microstructures. This thesis explores potential of new printing strategies, which could lead to good melting of printed component and reaching to better structure without porosities. Based on analysis of actual state, software for calculation of laser trajectory was made with use of new printing strategy. Also, process parameters obtained from technical articles and from experiments made on Institute of Machine and Industrial Design on Faculty of Mechanical Engineering BUT in Brno were compared. This comparison led to suggestion of test set of components with new parameters and strategies. This set could lead to new researches in this issue.
