DEVELOPMENT OF FGF 3D PRINTER

Abstract

The paper presents the development of a 3D printer based on Fused Granulate Fabrication (FGF) technology with a working space dimension of 500x500x500 mm. The printer was developed in the Student Workshop of the Faculty of Mechanical and Civil Engineering in Kraljevo as part of student activities and the completion of graduate work in the Mechanical Engineering study program. The conceptual design was based on a comparative analysis of existing technical solutions for 3D printers and their advantages and disadvantages. Based on the drawn conclusions a number of requirements were formed which need to be implemented in a new technical solution. The development included the following activities: defining the kinematic structure of the machine, detailed design, machine control based on the Arduino platform, specification of mechanical parts and electronic components, as well as configuring and entering the basic control program.At the end of the paper, the appearance of the constructed 3D printer is presented, along with one of the test examples used to evaluate the machine's performance.
