Abstract

Based on the unique additive manufacturing process, a dual-notch void model is proposed to explain three tensile strengths of a 3D printed polymer along three major directions. This model incorporates the strength/notch angle relation and provides a relative magnitude of three tensile strengths, i.e., Sx (axial strength) > Sy (transverse strength) ≥ Sz (inter-layer strength).
