Sažetak

Područja primjene aditivne proizvodnje danas su brojna i raznovrsna. Aditivna proizvodnja, poznatija pod imenom 3D tisak, doživjela je nagli porast u popularnosti nakon 2010. godine zaslugom RepRap projekta. Dostupnost jeftinih 3D printera i profesionalnih usluga 3D tiska rezultirala je povećanim interesom za 3D modeliranje i izradu 3D modela koji iskorištavaju prednosti koje aditivna proizvodnja nudi. Daleko napopularniji izražaj u stilu modeliranja i izgledu modela je korištenje 3D mrežastih struktura koje je vrlo teško ili čak nemoguće postići klasičnim metodama proizvodnje. Izrada modela pomoću mrežastih struktura ima brojne prednosti, poput uštede materijala, ubrzanja izrade modela i futurističkog izgleda. U radu su istražena područja 3D dizajna koja najviše profitiraju korištenjem mrežastih struktura, te tehnike njihovog generiranja, uz naglasak na proceduralni pristup modeliranju koji omogućava brzu izmjenu izgleda modela i geometrijskih karakteristika mrežastih struktura. Poseban naglasak stavljen je na korištenje najpopularnije potrošačke tehnologije 3D tiska (Fused Deposition Modeling) za izradu modela koji koriste mrežaste strukture. Istražena je učestalost upotreba mrežastih struktura na najpopularnijim online repozitorijima 3D objekata i 3D printanih modela.

Procedural generation of 3D mesh structures in additive manufacturing

Abstract

Fields of application of additive manufacturing today are numerous and various. Additive manufacturing, better known as 3D printing, has experienced a sharp rise in popularity after 2010 thanks to the RepRap project. The availability of low-cost 3D printers and professional services for 3D printing has resulted in an increased interest in 3D modeling and creation of 3D models that take advantage of the benefits that additive manufacturing offers. By far the most popular style of modeling and design is the use of 3D mesh structure which is very difficult or even impossible to achieve with classical methods of production. Creating models using the mesh structure has many advantages, such as saving material, accelerating development of models and futuristic look. This paper examines fields of 3D design that have the most benefit by using mesh structure and techniques of their generation, with an emphasis on procedural modeling approach that allows quick-change of model looks and geometric characteristics of mesh structure. Particular emphasis is placed on the use of the most popular consumer technology of 3D printing (Fused Deposition Modeling) for creating models that use mesh structures. The frequency of use of the mesh structure on the most popular online repository of 3D objects and 3D printed models was explored.

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.
