Abstract
Additive manufacturing (AM) is a technology adopted in numerous industries for rapid prototyping and fabrication. One of the AM technologies is Material Extrusion (ME), according to ISO/ASTM 52,900 standard. Polylactic acid (PLA) is a thermoplastic employed in most of the low-cost 3D printers. Owing to its widespread use, it is fundamental to understand the relationship that exists among the quality of parts made of PLA produced by ME, their mechanical properties as well as their mass and processing time, considering novel infill patterns proposed by various slicer software. This paper proposed an experimental study to optimize these variables by modifying three key parameters (infill pattern, build orientation, and infill percentage) in 3D printing of PLA. The effects of these parameters are analyzed using the Taguchi Methodology and an analysis of variance (ANOVA). A desirability analysis was employed to obtain a set of parameters that allowed the best trade-off among all the variables.
