AB Polymer additive manufacturing has advanced from prototyping to producing essentialparts with improved precision and versatility. Despite challenges like surface finish and wear resistance,new materials and metallic reinforcements in polymers have expanded its applications,enabling stronger, more durable parts for demanding industries like aerospace and structural engineering.This research investigates the tribological behaviour of FFF surfaces by integrating copperand aluminium reinforcement particles into a PLA (polylactic acid) matrix. Pin-on-disc tests wereconducted to evaluate friction coefficients and wear rates. Statistical analysis was performed tostudy the correlation of the main process variables. The results confirmed that reinforced materialsoffer interesting characteristics despite their complex use, with the roughness of the fabricated partsincreasing by more than 300%. This leads to an increase in the coefficient of friction, which is relatedto the variation in the material’s mechanical properties, as the hardness increases by more than 75%for materials reinforced with Al. Despite this, their performance is more stable, and the volume of materiallost due to wear is reduced by half. These results highlight the potential of reinforced polymersto improve the performance and durability of components manufactured through additive processes.
