Manufatura aditiva na engenharia: validação do uso de PLA com adição de fibra de carbono para obtenção de melhor propriedade mecânica em corpos de prova confeccionadas em impressora 3D

Abstract

This academic work consists of the practical application of destructive mechanical tests for the comparative and quantitative characterization of specimens made by a 3D printer, whose process model used is the FDM, using filaments of two different materials, PLA and PLA with addition of carbon fiber. This research aims to formalize issues related to this new market, which has revolutionized the field of mechanical manufacturing and which has been serving as a gateway for many companies in this new industrial era called Industry 4.0. The 3D printing market offers many alternatives and solutions that meet the interests of the current economy, but with this, it is also necessary that studies and scientific research evolve together with this one so that the most appropriate use of this new technology is possible. The conclusion of this work will complement the material developed so far, about the true benefits of using composites as filament material for 3D printing or even the lack of these, in order to prevent the use of companies that develop certain filaments promising mechanical characteristics that are not always attended to.
