IZRADA VIRTUALNOG MODELA PISAČA ADITIVNE TEHNOLOGIJE PRIMJENOM TEHNOLOGIJE CNC UPRAVLJANJA

Postupak 3D printanja omogućuje izradu obradaka iznimno kompleksne geometrije, te se temelji na načelu nanošenja čestica materijala u tankim slojevima. Obradak nastaje iz računalnog modela koji je nastao koristeći CAD progam ili postupkom povratnog inženjerstva. Kroz ovaj rad dan je pregled nekih postupaka aditivne tehnologije sa svojim prednostima i nedostacima, te su analizirani neki od najćešće prisutnih niskobudžetnih FDM 3D printera na tržištu. Prema analizi 3D printera koji su spomenuti u radu izrađen je virtualni model 3D printera koji bi u skoroj budućnosti trebao biti i sastavljen. Opisani su potrebni dijelovi za izradu 3D printera te definirani troškovi pojedinih komponenata.The 3D printing process allows the production of extremely complex geometry and is based on the principle of application of thin layer material particles. Workpiece is generated from a computer model that was created using a CAD program or by reverse engineering. This paper presents an overview of some additive technology processes with its advantages and disadvantages, and analyzed some of the most common low-cost FDM 3D printers on the market. According to the analysis of 3D printers mentioned in the paper, a virtual model of 3D printers was created which should be completed in the near future. The necessary parts for making 3D printer and the cost of individual components are described
