Projeto e construção de uma impressora 3d baseada na tecnologia da modelagem por fusão e deposição

Abstract

Recently, new manufacturing techniques have proven to be great transformers being pointed as the basis of the new industrial revolution. One of these techniques relates to additive manufacturing, a process that creates multiple layers based on material deposition, produces on a low scale, generally faster than traditional processes and is capable of achieving geometries that are not met by conventional manufacturing. There are several additive manufacturing techniques, and fusion and deposition modeling is the most common 3D printing technology. This technology refers to any process that creates layered objects, produced from a semiliquid material that comes out through a computer controlled nozzle. This work has as its main objective the development of a design and construction of a 3D printer based on the technology of fusion and deposition modeling. The specific objectives of this work are the development of the structure, components specification, application of a control solution in Arduino, fabrication, assembly and realization of tests and experiments. In this way, a thorough study on the main techniques of additive manufacturing, operation and use of a specific software and firmware to the application were required. After the assembly and calibration of the printer, the established criteria were met and the potential and quality of the printed parts were verified.
