Additive manufacturing (AM) by FDM (Fused Deposition Modeling) has been increasingly adopted due to the low cost
of 3D printers as an option capable of producing parts with complex geometries. Since the FDM process is a layer-by-layer
manufacturing method, the characterization of the behavior of parts manufactured by this technology, especially with regard to
anisotropic mechanical properties, has led to many works relating printing parameters with tensile strength. However, the use of
specimens with the conventional flat "dog bone" and cylindrical geometries specified in the ASTM-638 standards do not
perfectly suit the special characteristics of parts produced by FDM, since these standards were created for solid and isotropic
materials.
