Possibilities of using aditive technologies in direct manufacturing of foundry moulds
Herzán, Jiří ; Šlajs, Jan (referee) ; Horáček, Milan (advisor)
The bachelor thesis deals with the production of foundry molds with using additive technologies. At first, the additive technologies are distributed according to ASTM (American Society for Testing and Materials) and subsequently according to the state of the base material. Then, three types of technologies, that can be manufactured by Rapid Prototyping are described. The last chapter of the bachelor thesis is a real example of the production of a prototype fan casting from aluminum alloy AlSi9Cu3(Fe), which was casted into a printed mold by “3D Sand Printing” technology. Based on the obtained data were assessed technical, time and cost parameters of manufacturing the fan. The findings were compared with the molding technology of the ordinary printed pattern, which is an alternative to prototype production. The casting of the fan was cast in Armatmetal s.r.o. in Olomouc.

Production of castings by the Full-Mold casting using 3D printed models
Svoboda, Jaroslav ; Jelínek, Radim (referee) ; Bořil, Petr (advisor)
The aim of the work is to produce a casting using the evaporable model method with the use of 3D printed models. First, the thesis conducts a research on the topic and then discusses the process of producing a casting using this method. The PRUSA MK3S+ 3D FDM printer was chosen for the production of the model and HIPS and PMMA filaments were selected. This is followed by the selection of a model coating suitable for this technology, moulding into non-permanent sand moulds and casting the models. Finally, the final surfaces of the cast models with and without coating are compared.
