Abstract
Generally, the devices for dimensional control used in segments such as mechanical metal and mining are manufactured of steel or aluminum, materials that offer great resistance to fatigue and wear. The objective of this study is to replace a dimensional control device made of welded ASTM A36 steel sheets and steel tubes for one made of polyamide composite with glass fiber (PA 6 GF30 and PA 6.6 GF50) using the Material Extrusion process with the Additive Manufacturing (AM) technology. This is needed to achieve ergonomic requirements according to the NIOSH equation, eliminating possible failures in conventional operations and decrease the mass. The comparison between the steel dimensional control device and the PA 6 GF30 / PA 6.6 GF50 device was performed using the Finite Element Method (FEM) applied to deflection and wear resistance. An acceptable displacement was obtained for both composites, and also a reduction in the mass of the device of 67.5% for PA 6 GF 30 and 56.3% for PA 6.6 GF50. In conclusion, both composites have the capacity to withstand the same efforts as steel.
