Determination of Calibration Corrections and Study of the Reproducibility of a 3D Printer

Additive manufacturing technologies, among which is 3D printing, is one of the fundamental pillars of industry 4.0, since it allows to obtain prototypes and manufactured parts in a fast, versatile and economical way. To ensure the quality of production, it is necessary that all parts obtained through any manufacturing process meet the specifications of the design. However, it is not enough for a certain part to meet the dimensional design specifications, but most parts manufactured on the same machine must do so. This paper proposes two pattern models to study the reproducibility and for the correction of the scales that must be applied to a commercial 3D printer to obtain printed parts by fused filament deposition (FDM).
