3D print of nanocomposite photopolymer systems
 Sevriugina, Veronika ; Lepcio, Petr (referee) ; Ondreáš, František (advisor)
This master’s thesis deals with the preparation of nanocomposite photopolymer systems for 3D printing. The composition and structure were studied by thermogravimetry (TGA) and scanning transmission electron microscopy (STEM). The kinetics of photoreaction with gradually increasing content of Fe3O4 and AZO particles in a commercial methacrylate resin was also characterized by the creation of Jakobs working curves, photorheology, and differential scanning photocalorimetry (photo-DSC). Subsequently, the effect of composition on the printability of materials was observed. Part of the work is also devoted to the characterization of the influence of particles on the thermomechanical properties of the resulting products using dynamic-mechanical analysis (DMA) and on the mechanical properties in pressure.

Effect of the diameter of the nozzle on the 3D printer print quality
 Kutil, Jaroslav ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
The matter of this thesis is to find the influence of the diameter of the nozzle on the 3D printer´s print quality. The first part briefly characterizes the Rapid Prototyping technology and describes the RepRap project. The second part describes the construction of the experimental FMD 3D printer. The following section deals with technical printing parametres and their influence on the printed product. The experimental part of the thesis is focused on the impact of the discharge nozzle diameter on the mechanical properties, surface quality and shape accuracy of the final product and on the following recommendations of operational parametres.
