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.

Manufacture of cylinder head casting for engine renovation Jawa 50
Pastyřík, Petr ; Myška, Martin (referee) ; Bořil, Petr (advisor)
This project elaborats the manufacture of a cylinder head casting for an engine renovation of Jawa 50. Based on the literary pursuit of suitable foundry technologies and using 3D printing in foundry a casting production technology was designed and the cylinder head was made. The part was designed in the CAD software and then printed on a 3D printer. The printed model was formed in ceramic shell form, then melted and the form was annealed. After that the cast was casted. The last operations were fettling and finishing machining.
