Vizualizacija i analiza 3D modela pomoću metode konačnih elemenata i 3D printanje u medicini

3D model visualization and analysis using Finite Element Method and 3D printing in medicine

Sažetak

Napredak medicine leži u napretku tehnologije. Suvremenu proizvodnju medicinskih pomagala te medicinsku dijagnostiku u današnje vrijeme nije moguće zamisliti bez korištenja suvremenih alata kao što su računalni programi za 3D modeliranje (SolidWorks, Pro/Engineer), simulaciju (Abaqus, ANSYS), animaciju te uređaji za brzu izradu prototipova (3D printer). U radu prikazan pojednostavljeni model Charite međukralježničkog umjetnog diska, koji je modeliran u programskom paketu SolidWorks. Model je diskretiziran mrežom tetraedarskih konačnih elemenata drugog reda, a simulacije su provedene za četiri različita opterećenja u programskom paketu Abaqus. Pomoću 3D printanja, kojem je baza 3D modeliranje, takvi implantati i proteze će se izrađivati od matičnih stanica pacijenata, u vrlo kratkom vremenu sa znatno smanjenim troškovima što će pridonjeti revolucionarnom razvitku i napretku medicine.

Abstract

The power of advanced medicine is one of the great stories of modern science, built on a long succession of discoveries and technological breakthroughs. Medicine development lies in technology development. Modern manufacturing of medical supplies and medical diagnostics today can not be imagined without the use of modern tools such as computer programs for 3D modeling (SolidWorks, Pro/Engineer), simulation (Abaqus, Ansys), animation and devices for Rapid Prototyping (3D printer). Th is paper presents a simplifi ed model of intravertebral artifi cial disc Charite, which is modeled in SolidWorks software package. Th e model is discretized tetrahedral fi nite element mesh of the second order, and the simulations were performed for four diff erent loads in Abaqus. Using 3D printing, which is the base of 3D modeling, such a type of implants and prostheses will be produced in a very short time with a much lower costs, which will bring revolution and medical advances.

Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
