Klátil, Ondřej ; Kaněra, Miloš (referee) ; Jelínek, Radim (advisor)
The work is focused on the production of a replica switch cover for the ČZ 250/471 motorcycle from 1974. The theoretical part of thesis includes a review of the production of permanent and expendable patterns, mold making, various casting methods, additive technologies categorized under rapid prototyping methods, and a description of scanning methods. In the experimental part, the informations from the theoretical part are verified through the experiment of producing the switch cover replica. The original part was first scanned, then the scan was edited and converted into a solid model, which was then printed on an FDM printer as a expendable pattern for the investment casting method using shell molds. These castings were then evaluated against the originals. At the end of the experiment, surface defects were found, the causes of which could not be definitively explained. Subsequently, various production methods were outlined for specific ranges according to the number of products.
