Abstract
This work develops an applied manufacturing process of test pieces for its subsequent traction test. These take place in a universal testing machine. During first step, a 3D CAD standard model is designed. Next, the model is 3D printed, using PLA as raw material. Likewise, prior to the casting process, sprue design and plucking angle need to be calculated. To develop this work, the raw material for the manufacturing process is brass with a composition of 35% of zinc (Zn) and 65% of copper (Cu). It melts at a temperature of 940 ºC. Thus to perform the cast, an electric oven and a graphite crucible are needed. When the metal is finally melted, it is poured in the sand molds. In order to be able to verify the quality of the manufactured piece, a traction test is performed, allowing to obtain the breaking limit, elastic limit, lengthening and the stiffness module. This innovative process has been designed entirely for its application in technical teachings and laboratory experiences.
