Estudo e projeto de aeromodelos fabricados via impressão 3D e comparação com modelos convencionais

Abstract

With the aid of rapid prototyping is possible to obtain high repeatability, production of parts with high complexity, shorter production time compared to a manual cutting process. Moreover, the manufacture of airplanes manually presents certain problems such as high cost, need for skill with balsa wood handling and other fragile materials, low repeatability and high production time of the parts. From the specimens made of balsa wood and ABS, it was observed by testing the wood has greater tensile strength. On the other hand, ABS has greater elongation. From the weight viewpoint the model presented ABS in an increase of approximately 77% by weight. The final cost of each model, where the ABS decreased by nearly 51% in the value of the final model, was also evaluated. With these facts, it was possible to say that the production of a three-dimensional printed model airplane com ABS shows itself unfeasible.
