Abstract

The evaluation of the tensile strength of printed parts by means of fused deposition modeling (FDM) or fused filament fabrication (FFF) is essential, since parts whose resistance does not differ significantly depending on the percentage of filling used can be obtained, optimizing the use of the material. The present work details the analysis of polylactic acid (PLA) specimens manufactured according to ASTM D 638 with different percentages for the most commonly used filling patterns (Honeycomb, Octagram, Stars, Archimedean, Hilbert and Triangles). With the help of an analysis of variance and a design of experiments with a single factor, the appropriate percentages for printing parts according to the desired filling pattern are obtained.
