Výroba modelu 21.04.2014

Před výrobou modelu si je nutné uvědomit jak velký model bude, jaké budou požadavky na přesnost a povrch. je také nutno si uvědomit kolikrát budeme chtít model pro výrobu formy použít a zda jej například bude dobré zachovat pro výrobu modelu dalšího.

            

Model se dá vyrobit z různých materiálů a různým způsobem. Nyní vynechám popis výroby modelu frézováním, které je ve většině případů asi nejlepším řešením. Frézování je však náročné na finance i přípravu(kreslení). Nyní bych se chtěl věnovat zejména způsobům, které si může dovolit téměř každý a zároveň lze při nich dosáhnout přijatelných výsledků. Také zde popíši chyby, kterých bychom se měli vyvarovat, abychom měli více radosti než zklamaní.

Menší a středně velké modely se velmi často vyrábí z pěnového polystyrenu, dřeva, překližky, MDF desek(obdoba dřevotřísky jen z jemnějších vláken), laminátu, sádry, balsy, polyuretanových desek, epoxidových bloků.

                                        

Jedním z jednoduchých postupů a často používaných je výroba modelu z pěnového polyesteru. Je výhodné k tvarování  a opracovávání používat odporový drát a trafo. Abychom mohli odporový drát dobře vést v pěnovém polystyrénu je dobré si připravit žebra po kterých odporový drát přesně bude klouzat.
