Abstract
The three-dimensional parameterized prototyping is a fundamental technology for the free fabrication of objects. It is used in manufacturing, commercial, academic, and domestic environments and allows the wide production of parts in pilot or real scale, with potentially low values and increasingly smaller, if compared to alternative manufacturing methods. It presents greater recurrence in medicine, biology, and engineering. Studying the behavior of raw materials used for 3D printing is a valuable tool to understand and develop more efficient models according to the application. It is possible to collect mechanical data through tensile strength tests using a universal machine and test specimens of different materials and printing configurations. ABS material is the lowest cost on the market, presents excellent cost-effectiveness and requires some skill for plotting. PLA is a widely commercialized material, requires less skill in operation and has greater mechanical flexibility. The development is permeated using a GTMax 3D H4 Core 3D Printer for plotting the CP's and the consequent use of the Universal Machine for Tensile tests. It's important to mention that every machinery is available at IFSP. The viability of the project lies in achieving the objectives of comparing the mechanical resistance of the materials, with values obtained at the maximum tension of 19 MPa and comparing them with commercial values and those predicted in the literature.
