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.

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.

3D printing of complex structures using light cured resins
Vozárik, Andrej ; Zbončák,, Marek (referee) ; Jančář, Josef (advisor)
This bachelor thesis deals with preparation of acrylate photopolymer resins for 3D printing with emphasis on complex structures. The work deals with the curing characteristics of resins with gradually increasing CN966H90 oligomer content. Subsequently the effect of composition and individual print settings on the quality of the created complex structures is observed. For the basic characterization of photopolymer resins, Jacobs working functions were created, the structure of the cured resins was observed with CLSM and rheologically determined the effect of composition on viscosity. Part of the work is also devoted to the influence of composition on the mechanical properties in compression and tension for cured resins. The effect of exposure time on print quality was observed on calibration bodies. Finally, from the results obtained from previous measurement the printing process was adapted for print of the complex structures.
