Additive manufacturing, also known as 3D printing, has experienced a surge in popularity in recent years. Currently, the additive manufacturing market is valued at approximately twenty billion dollars, with a projected annual growth rate of twenty percent for the period between 2023 and 2030. This technology is fundamentally altering the approach of product designers towards prototyping, and increasingly, 3D printed components are being integrated as functional parts in consumer products. Given the significance of additive manufacturing, it becomes imperative to characterize the mechanical behavior of 3D printed parts to ensure they possess the required rigidity and resistance for their intended applications. However, recent efforts in characterizing the mechanical behavior of 3D printed parts have primarily focused on tension behavior, neglecting the crucial aspect of shear stress behavior, which is highly relevant in various applications such as axles, pins, and rods. This study investigates the effects of variations in 3D printing parameters on shear behavior through experimental torsional testing. Test specimens with a diameter of 9 mm, according to ASTM E143-02 standards, were subjected to testing, varying parameters such as infill pattern, infill percentage, and printing orientation. Results indicate that printing orientation has the most significant influence on shear behavior during torsional testing, while infill percentage and infill pattern exhibit minor effects. The findings highlight the significant influence of printing parameters on the mechanical behavior of 3D printed parts. Further experimentation, including tests involving variations in parameters such as layer height, printing speed, and material composition, is essential to comprehensively understand their impact on mechanical behavior.
