Abstract:<p>3D printing manufacturing method gains significant attractions from industries due to its advantages over other production methods. Polylactic Acid (PLA), a biodegradable feedstock in 3D printing and one of the major filaments in the market, is investigated. Impulse Excitation Technique (IET) is used to obtain Young’s modulus of 3D-printed PLA specimens. The results are then compared with those achieved through experimental tensile testing. Displacement laser sensors, attached on the vertical base alo… Show more
