Traditional rigid-body mechanisms consist of multiple components to perform their functions, which often leads to issues such as back-lash, wear, increased part count, weight, assembly cost, and time, as well as the need for regular maintenance. To address these challenges and enhance performance, the use of compliant mechanisms has shown significant benefits across various fields. Unlike rigid-body mechanisms, compliant mechanisms utilize the deflection of flexible members rather than relying solely on movable joints, resulting in reduced complexity, improved reliability, and greater efficiency. This paper explores the advancements in compliant mechanism design and their impact on reducing common mechanical issues. A Clothespin mechanism supported by a compliant mechanism was designed and studied in this study. SolidWorks software was used for compliant mechanism modeling, and the Ansys software was used for static analysis. The clothespin was designed as a single piece using ABS material. The FDM (Fused Deposition Modeling) printing technology was used and Ultimaker 3 3D printer was used for prototyping by altering parameters such as angle, density, and layer height. Fatigue life of the printed parts were studied using a developed experimental setup. The testing results showed that developed compliant mechanism can be used to replace existing clothespins which have several parts. It is an indicate of the success of compliant mechanisms for existing complex mechanisms. Further, increasing infill density and lowering layer height result in good fatigue cycles in a 90-degree printing.
