L'etude de l'effet de la forme et du taux de remplissage sur les propriétés mécaniques des piéces réalisées avec l'impression 3d

Abstract

This thesis presents the study of the effect of the shape and the filling rate on the mechanical properties of parts made with 3D printing with PLA filament. Different patterns and filling rates were generated using a script implemented in the ABAQUS software and then a finite element simulation of quasi-static compression was performed on cylindrical samples with a height of 15 mm and a diameter of 25 mm. The results obtained from the critical force have been validated with experimental tests, they show that the pattern, the filling rate and the materials used have a major impact on the mechanical resistance of the part.
