Tensile force–Elongation curves of 3D-PPOT materials using virgin PLA filament and PLA/2.5%CB (conductive) filament printed on 14 picks/inch PET woven fabrics in machine direction. (1) and (2) represent the maximum strength of the PLA layer and the PET fabric of the 3D-PPOT using virgin PLA filament printed in machine direction respectively. (3) and (4) represent the maximum strength of the conductive PLA layer and the PET fabric of the 3D-PPOT using PLA/2.5wt.% CB filament printed in machine direction respectively.
