PLA Spring Motor Demonstrator

myminifactory

A revolutionary motor demonstrator crafted entirely from PLA, featuring a self-contained spring mechanism that requires no external power sources or motors to operate. This innovative device can serve as an engaging educational tool for students of mechanical engineering, providing hands-on experience with the fundamental principles of torque versus velocity and the forces generated by springs printed using various infill settings, heights, and thicknesses. To further explore its capabilities, watch the accompanying video: https://www.youtube.com/watch?v=e4j5zX3Sbnw&list=UUv_zm49u-RjnCJVwhUO-ecA. A rolling chassis version of this demonstrator is available for those interested in taking their experiments to the next level. When operating the PLA Spring Motor Demonstrator, always wear safety glasses as a precautionary measure, even though I've successfully operated it over 100 times without incident. However, I recommend exercising caution due to the potential risk of spring failure and flying debris. This design was created using Sketchup 8 and printed on a Makerbot Replicator 2 with Makerware 2.3.3.42, showcasing the versatility and capabilities of PLA as a printing material.
