New paper published: Comparative study about dimensional accuracy and form errors of FFF printed spur gears using PLA and Nylon

This article from the TECNOFAB (Manufacturing Technologies) and CDEI-DM (Industrial Equipment Design Center - Machine Dynamics) research groups corresponds to the line of research in additive manufacturing processes, specifically the FFF ("fused filament fabrication").

The article presents a methodology for the generation, manufacture and verification of gears 3D printed in plastic material, and compares the dimensional accuracy and form error of parts obtained in two different materials: polylactic acid (PLA) and Nylon.

The results show that, in general, dimensional errors of PLA parts are lower than those of Nylon parts, while Nylon parts, which were printed with a lower infill percentage, show lower form errors than the PLA parts.
