Due to its building process, the mechanical properties of a 3D-printed object are substantially different from those of the same object, made of the same material, but obtained by a different manufacturing process. Tensile tests were carried out on standard specimens, which were 3D-printed with a Builder Premium™ FDM printer. Three different plastic and composite materials were tested and their stress-strain curves were obtained; significant parameters such as ultimate tensile strength and Young’s modulus were calculated and compared.

Abstract
Due to its building process, the mechanical properties of a 3D-printed object are substantially different from those of the same object, made of the same material, but obtained by a different manufacturing process. Tensile tests were carried out on standard specimens, which were 3D-printed with a Builder Premium™ FDM printer. Three different plastic and composite materials were tested and their stress-strain curves were obtained; significant parameters such as ultimate tensile strength and Young’s modulus were calculated and compared.File in questo prodotto:
