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.

The influence of heat treatment on magnetic properties of additive manufactured stainless steel components
Schäffer, Matúš ; Hutař, Pavel (referee) ; Paloušek, David (advisor)
The aim of this master thesis is selection of heat treatment for additive manufactured multimaterial components composed of 1.4404 and 1.4542 stainless steels regarding their magnetic and mechanical properties. Individual materials were studied after fabrication and also after the same heat treatments. The chosen process consists of solution annealing and subsequent precipitation hardening. A significantly higher value of maximum relative permeability and lower of coercive field of 1.4542 steel were achieved. At the same time, the relative permeability of 1.4404 was not considerably influenced. A decrease in Rp0,2 of 1.4404, but an increase in Rm and Rp0,2 values of 1.4542 steel were observed. Elongation at break A increased in the case of both alloys. The experiments proved that multimaterial components composed of these stainless steels can be successfully manufactured by SLM technology. It is therefore possible to design and manufacture stainless steel components of magnetic circuits and adjust their magnetic and mechanical properties by heat treatment.
