The advent of 3D printing technology has heralded a new era in manufacturing, offering unprecedented flexibility, customization, and efficiency in product development and production. This review paper delves into the intricacies of fabricating a 3D printer and subsequently evaluating the mechanical properties of Polylactic Acid (PLA), a commonly used material in additive manufacturing, through tensile testing using Universal Testing Machines (UTM). The fabrication process of the 3D printer is meticulously outlined, encompassing the selection of high-quality components, precise assembly procedures, and meticulous calibration to ensure optimal performance. Particular attention is paid to any modifications or customizations made to the printer to tailor it to the specific requirements of the project . Following the fabrication phase, PLA specimens are meticulously prepared according to industry standards to ensure uniformity and reliability in subsequent testing. These specimens are then subjected to rigorous tensile testing using a UTM to evaluate their mechanical properties under varying load conditions. The results of these tests, including stress-strain curves, ultimate tensile strength, yield strength, and modulus of elasticity, are meticulously analyzed and discussed in detail. The implications of these findings for the broader field of additive manufacturing and material science are carefully examined, shedding light on the performance characteristics of PLA and the efficacy of the fabricated 3D printer in producing high-quality printed parts. Furthermore, avenues for future research and potential improvements in fabrication and testing methodologies are explored, aiming to propel the field of additive manufacturing forward. This comprehensive review provides invaluable insights into the fabrication of 3D printers and the assessment of material properties, serving as a foundational resource for researchers, engineers, and enthusiasts alike seeking to advance the capabilities and understanding of additive manufacturing technologies.
