Additive manufacturing is a tool in the development and innovation of products, so in this work an analysis is performed, by means of a statistical model called ANOVA, to identify analysis trends in applied engineering and research environments. The measurements corresponding to the parts manufactured in three printing machines were carried out to corroborate the efficiency of each equipment, dimensional analysis and, finally, efficiency in measuring instruments, using the ANOVA procedure in two factors, with computational environments. The specimen is manufactured with PLA (Polylactic Acid) in fused material deposition (FDM) equipment, with 30% filling. As part of the results of the analysis, the functionality of the printers to obtain a specimen is determined, evaluating from the point of view of statistical process control and identifying that the printers do not maintain equal conditions in the processing of test specimens.

Keywords : ANOVA analysis; matching; 3D printing; measurement; variance.
