Design of special extruder for 3D printing
Maňák, Juraj ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The bachelor thesis focuses on the design of a print head for 3D printing of cement mixtures. The work discusses current 3D concrete printing technologies, concrete transport options, and the properties of concrete mixes and admixtures. Next, three conceptual printhead solutions and two shaft bearings are proposed. Using multi-criteria analysis, the resulting variant is selected and it is structurally processed. The designed printhead allows continuous printing and mixing of the cement mixture and admixture of the setting accelerator.

Development of materials for 3D printing of elements meeting the requirements of transport structures
Romanová, Dorota ; Melichar, Jindřich (referee) ; Žižková, Nikol (advisor)
This bachelor thesis deals with the use of supplementary cementitious materials as a partial replacement of Portland cement in cement composites, focusing on the requirements of transport constructions. The theoretical part consists of a description of the input raw materials as well as cement substitutes, the studied properties of the 3D printed mixtures and a description of the characteristics of the technology. The practical part is focused on the experimental testing of the selected properties with monitoring of the influence of polymer and bio-polymer additive dosage in the proposed formulations and subsequent analysis of the most convenient one for 3D printing.
