Krok 1: Vytvo\u0159en\u00ed p\u0159edlohy<\/h4>\n

K tvarov\u00e1n\u00ed d\u00edl\u016f pou\u017eijte vosk, d\u0159evo nebo dokonce plast vyti\u0161t\u011bn\u00fd na 3D tisk\u00e1rn\u011b. To bude v\u00e1\u0161 pozitivn\u00ed vzor.<\/p>\n

Krok 2: P\u0159\u00edprava krabice s formou<\/h4>\n

Vlo\u017ete p\u0159edlohu do krabice (ba\u0148ky) a pevn\u011b ji zabalte do zelen\u00e9ho p\u00edsku (p\u00edsek sm\u00edchan\u00fd s hl\u00ednou a vlhkost\u00ed).<\/p>\n

Krok 3: Odstran\u011bn\u00ed vzoru<\/h4>\n

Opatrn\u011b vyjm\u011bte hlavu. Nyn\u00ed m\u00e1te dutinu ve tvaru p\u0159edm\u011btu.<\/p>\n

Krok 5: Nalijte hlin\u00edk<\/h4>\n

Pou\u017e\u00edvejte ochrann\u00e9 pom\u016fcky. Do formy pomalu nalijte roztaven\u00fd hlin\u00edk.<\/p>\n

Krok 6: Ochlazen\u00ed a rozbit\u00ed formy<\/h4>\n

Nechte ji vychladnout a pak odlitek vyjm\u011bte. Podle pot\u0159eby jej o\u010dist\u011bte a opilujte.<\/p>\n
