Original abstract
The research focused on the production of prototype castings, which is mapped out starting from the drawing documentation up to the production of the casting itself. The FDM method was applied for the production of the 3D pattern. Its main objective was to find out, what dimensional changes happened during individual production stages starting from the 3D pattern printing, through a silicon mould production, wax patterns casting, making shells, melting out wax from shells and drying, up to the production of the final casting itself. 5 measurements of determined dimensions were made during the production, which were processed and evaluated mathematically. A determination of shrinkage and a proposal of measures to maintain the dimensional stability of the final casting so as to meet requirements specified by a customer were the results.

Výzkum byl zaměřen na výrobu prototypových odlitků, který je zmapován od výkresové dokumentace až po výrobu vlastního odlitku. K výrobě 3D modelu byla použita metoda FDM. Hlavním cílem bylo zjistit, k jakým rozměrovým změnám došlo během jednotlivých fází výroby a to od tisku 3D modelu, přes výrobu silikonové formy, odlití voskových modelů, vytvoření skořepin, vytavení vosku ze skořepin a vysušení, až k samotné výrobě finálního odlitku. Během celé výroby byly prováděny měření 5 stanovených rozměrů, které byly matematicky zpracovány a vyhodnoceny. Výsledkem bylo stanovení smrštění a navržení opatření pro zachování rozměrové stálosti finálního odlitku tak, aby splňoval požadované nároky zákazníka.
