Abstract: 
This study evaluates the effectiveness of different 3D printing filaments for compliant mechanisms, with a focus on cost, mechanical performance, and recyclability. Specifically, the research investigates the coefficient of stiffness of an ortho-planar spring, the rotational range of a cross axis flexural pivot, and the number of cycles a compliant bistable switch can endure. Using a 3D printer, filaments PLA, PLA+, PETG, ABS, and TPU were tested to determine their suitability for compliant mechanisms. Results indicate significant variation in durability and mechanical performance among materials, informing optimal choices for practical home-printed compliant mechanisms.
