Projeto de uma impressora 3D utilizando código aberto e Arduíno

Abstract

The technology called additive manufacturing is the technique of building threedimensional solids, layer by layer, on top of each other, until the object is formed. This work was developed using SolidWorks software for computational modeling and product development, and the knowledge acquired during the mechanical engineering course. Taking inspiration from several projects found and developed by the RepRap initiative, this is a forum with projects of great cost/benefit, in addition to work already done, in the same sense, such as one made at the institution itself, in the case of “Desenvolvimento de impressora 3D de baixo custo para prototipagem de peças para o meio rural”. During the work, it was possible to have a small sample of the development processes of mechanical devices. In addition, knowledge was obtained in the area of projects, operation of mechanisms, purchase of parts, analysis of manufacturers' catalogs and interpretation of national and international technical standards. It is also important to mention the implementation of software in this project, which work in an integrated manner with open source hardware. With the final project, it was possible to compare printers acquired through imports from China, such as those developed with national technology and importing as little as possible, in addition to the influence of this type of project in the educational environment for the creation of prototypes and in the study of engineering and computer-aided design, generating physical models of the projects. Finally, it was possible to understand the final cost of the product, in addition to all the technology used for its development, making it challenging, especially in the prototype automation configuration.
