ISBN 978-972-745-310-8978-972-745-310-8http://hdl.handle.net/10198/26087The use of additive manufacturing (3D printers) in the direct fabrication of commercial items is widespread, owing to the advancements and popularization of computer design programs (CAD) and 3D printers, particularly in the previous 10 years. Shimadzu Autograph AGS - X series universal testing machine was used for both tests. PLA+ can withstand larger stresses than ABS, with 44.2% and 25.73% higher tensile and yield strains, respectively. The modulus of elasticity of PLA+ is shown to be 61.99% greater than that of ABS. The goal of this study is to describe the most often used materials and procedures in 3D printing, as well as to characterize ABS and PLA polymers through tensile testing.eng3D printingMechanical characterizationconference object
