Abstract

Viseci dijelovi kao samostalne strukture nadogradene na podlogu ili prethodni sloj, sklone su uvijanju ili drugim deformacijama. Dakle, vecina 3D aditivnih procesa proizvodnje poput FDM/FFF, SLS, EBM, LOM, PBIH3DP i STL predstavljaju u procesu kreiranja 3D proizvoda inkrementalno slaganje tankih, fleksibilnih slojeva. Problem visecih dijelova genericki je termin za bilo koju "visecu" strukturu (strukturu negativnog kuta). Ukoliko se radi o objektima ciji viseci dijelovi premasuju kut od 45°, potrebno je pribjeci koristenju potpornih struktura. Potporne strukture podrazumijevaju pasivnu strukturu koja nije dio ispisanog objekta, a daje mu strukturalnu podrsku to jest onemogucava pojavu deformacije oblika. Upravo sve kompleksniji 3D modeli zahtijevaju mnostvo visecih dijelova. Medutim, da bi se stvorio kvalitetan proizvod uz sto manje otpada i pogresaka potrebno je u ranim fazama projektiranja, vizualizirati potporne strukture pomocu softvera.
