Abstract

Kroz rad je prikazana važnost i zastupljenost aditivne proizvodnje u suvremenoj industriji. Poseban naglasak stavljen je na postupak taložnog očvršćivanja koji se trenutno najviše primjenjuje. Sve veća popularnost i potreba za aditivnom proizvodnjom dovela je do razvoja i pojave velikog broja komercijalnih 3D pisača na tržištu. U teorijskom dijelu prikazane su najčešće izvedbe 3D pisača koji su trenutno dostupni na tržištu. U nastavku rada analiziran je komercijalni 3D pisač čiji se rad zasniva na postupku taložnog očvršćivanja. Zbog niza uočenih konstrukcijskih nedostataka, često je dolazilo do kvarova i zastoja stroja. Detaljno je prikazana konstrukcijska izvedba kroz 3D modele i analizirani su postojeći nedostaci. Cilj rada je bio predložiti rekonstrukcijske zahvate koji bi otklonili uočene nedostatke te omogućili ponovnu industrijsku primjenu stroja. Za sve rekonstrukcijske prijedloge izrađeni su detaljni 3D modeli, kao i potrebna tehnička dokumentacija.

Abstract (english)

This study presents the importance of additive production in modern industry. The focus is on the process of Fused Deposition Modeling (FDM), because it is currently amongst the most commonly used additive technologies. The growing popularity and need for additive manufacturing processes has led to the development of large number of commercial 3D printers on the market. The theoretical part of this paper presents the most common versions of 3D printers that are currently available on the market. Second part describes retrofitting of a 3D printer based on FDM process. Flaws in the design of this printer have led to the frequent breakdowns and downtime. The aim of the study was to propose modifications to the existing printer design which would eliminate the observed disadvantages and provide more robust and reliable operation of the machine. Detailed 3D models were made for all reconstruction proposals, as well as the necessary technical documentation.
