Abstract
Sve većim napretkom tehnologije dolazi do povezivanja više znanstvenih područja, kao što su u ovom slučaju strojarstvo i medicina. U slučajevima kada nisu dostupni crteži, tehnička dokumentacija ili računalni modeli pristupa se reverznom inženjerstvu. Primjer je medicina gdje se uz pomoć aditivnih postupaka izrađuje iskoristivi 3D model. Aditivna proizvodnja izravno gradi objekt iz digitalnog 3D modela dodavanjem materijala sloj po sloj. Cilj ovog rada je konvertirati podatke iz CT (engl. Computerized Tomography) sustava u CAD/CAM sustav te služeći se aditivnim postupkom stereolitografije izraditi fizički objekt. CT snimak oštećene ljudske lubanje spremljen je kao DICOM (engl. Digital Imaging and Communications in Medicine) format, koji je svojstven za medicinsku primjenu. Korištenjem softverskih programa, niz 2D slikovnih podataka transformira se u računalni 3D model koji se pohranjuje kao STL (engl. Standard Triangulation Language) format. Obzirom da je STL format mreža trokuta koja okružuje CAD model, kao takav ne zadovoljava funkciju. Zaglađivanjem površine pomoću interpolacije mreže trokuta u krivulje dolazi se do prihvatljivog izgleda lubanje. Tako dobivenim računalnim 3D modelom lubanje pristupa se rekonstrukciji na način da se od postojećeg zdravog dijela izrađuje implantat koji će nadomjestiti oštećeni dio. Na kraju se vrši postupak izrade lubanje i implantata postupkom stereolitografije. Krajnji rezultat je zadovoljavajući te je implantat uz male dorade spreman za upotrebu.
Abstract (english)
More and more advances in technology connect multiple scientific areas, such as mechanical engineering and medicine. In cases where drawings, technical documentation or computer models are not available, access to reverse engineering. An example is medicine where uses of additive methods made a usable 3D model. Additive production directly builds an object from a digital 3D model by adding layered material. The aim of this work is to convert data from a CT (Computerized Tomography) system into a CAD/CAM system and to use an additive process stereolitography to create a physical object. The CT scan of the damaged human skull was saved as a DICOM (Digital Imaging and Communications in Medicine) format, which is unique to medical applications. Using software programs, a series of 2D image data transforms into a digital 3D model that is stored as STL (Standard Triangulation Language) format. Since the STL format is a raw unstructured triangulated surface that surrounds the CAD model, it does not satisfy the function. Smoothing the surface by interpolating a raw unstructured triangulated surface into the curve results in an acceptable skull appearance. So obtained a digital 3D skull model is approaching reconstruction in such a way that an implant that replaces the damaged part is created of the existing non-damaged part. Finally, the skull and implant procedure is performed by stereolithography. The end result is satisfactory and the implant with slightly modifications is ready to use.
