Desenvolvimento de impressora 3D de baixo custo para prototipagem de peças para o meio rural

Abstract

With the emergence of industry 4.0, Maker or Do-it-Yourself culture, 3D printing has transformed the way products are created, efficiently producing parts and tools with the finishing and quality of large industries. In this way, 3D prototyping creates as an alternative the production of parts according to the individual needs of each user or branch of production, facilitating the production of objects or parts replacement for productive processes and prototyping, besides providing the improvement or assembly of new printers. The goal of the study was to develop a low-cost 3D printer that can be replicated and used by small producers and the creation of a free virtual library of parts and tools aimed at the agricultural sector. For the execution of the project, components were purchased in the national market for assembly of the printer, later configured and calibrated by comparing the quality of printed parts and costs, with a 3D printer in the Prusa i3 model, commercialized. With this study it was possible to construct a machine with low cost, quality in the printing of the objects and that can be used in agricultural production processes together with a digital library of tools and parts, interactive in form of site for download or loading files ready for printed.
