Evaluación en la aplicación de material compuesto alternativo en la fabricación en impresión FFF del Retrovisor Nissan Sentra B13 (2013).

Abstract

This research project focused on determining the viability of PolyMide™ CoPA as an alternative material for use in FFF 3D printing for the manufacture of a rearview mirror prototype, specifically in terms of mechanical and structural testing. The project also studied the effect of different infill patterns on mechanical and structural behavior. The tensile test results showed that the concentric infill configuration achieved very good overall performance, reaching the highest values and lowest variability in tensile strength (26.22 MPa) and tensile load (540.01 N). This infill configuration also exhibited the highest modulus of elasticity (1357.06 MPa). Conversely, the grid infill pattern showed the lowest values and exhibited high dispersion. In turn, the simulation carried out in the Altair SimSolid tool with a load value of 50N showed that the model in PolyMide™ CoPA reduced the critical displacement of 1.265 mm compared to 2.091 mm for ABS, which represented approximately a 40% reduction in material deformation, increasing the stability of the assembly and decreasing the probability of affecting the functional condition of the rearview mirror.
