AB In a previous work, dumbbell specimens were shown to be inadequate for the tensile testing of Additive Manufacturingmonolayers. Finite Element Method (FEM) has been used in this contribution for comparing tensile-stress distributions in bothconventional and rectangular samples. Different extrusion paths for the manufacturing via Fused Layer Modelling (FLM) weretaken into account. The calculations showed stress concentrations in the dumbbell type specimens in the zone of variable widthaway from the gauge length. The results were used for explaining the differences between mechanical behavior of dumbbell andrectangular specimens made with FLM from Poly-Lactic Acid (PLA). The mechanical behavior in the experiments closelymatches the FEM results. At least 20 % of the tested dumbbell specimens fractured away from the gauge length, compromisingthe resulting tensile strength data. Rectangular tensile test specimens are proposed as a better alternative.
