Configuração e montagem de equipamento de manufatura aditiva por extrusão de material com maior área de trabalho para o laboratório da UTFPR

Abstract

With the advent of globalization and the development of technology, 3D printing has been used recurrently in the industrial environment. However, purchasing a highcapacity printer for larger-scale printing is still a costly investment. In view of this, in the present work a 3D printer project with an extrusion area of 500x500mm was configured and assembled for the UTFPR laboratory. In order for the proposal to be implemented, a comparison was made between three types of printer configurations (Cartesian, corexy and delta) in which the corexy was chosen because it presents the lowest noise and vibrations among those presented, being ideal for models with large print area. After choosing the kinematics of the printer, it was decided to look for an already idealized project to base it on, where the main criteria were to be open source and to have two motors on the Z axis. After choosing the model project, the resizing was carried out 3D printer to the required size in order to achieve the required print area; the survey and purchase of all the items necessary for its construction were carried out. The assembly of the project began with the structure, the structure being manufactured from the welding of galvanized metalon tubes and all the polymeric structural elements manufactured using a 3D printer; then the structure was assembled, followed by the electronics, programming and finally the operation of the printer. As a result, the assembly of the 3D printer with a larger working area and a considerably smaller budget was consolidated, compared to commercial printers currently available in the technology market.
