This work presents a synthetic geometrical performance index that combines all dimensional and geometrical deviations of a printed part to express its quality. Smaller is the value of this index, greater is the part quality. The paper demonstrates the effectiveness of this index by printing a set of parts through Fused Filament Fabrication in a biological polymer. These parts, characterized by representive hollows, were measured by optical scanning technology. The proposed methodology shows the advantages of this index, thus future work can focus on further printing techniques and varying process parameter values.

Abstract

This work presents a synthetic geometrical performance index that combines all dimensional and geometrical deviations of a printed part to express its quality. Smaller is the value of this index, greater is the part quality. The paper demonstrates the effectiveness of this index by printing a set of parts through Fused Filament Fabrication in a biological polymer. These parts, characterized by representive hollows, were measured by optical scanning technology. The proposed methodology shows the advantages of this index, thus future work can focus on further printing techniques and varying process parameter values.
