artificial limb SMA cooling

This device is capable of lifting a 20 kg bag of cement with just 24 volts and 2.6 amps, making it an ideal candidate for producing complex parts through 3D printing, as well as cutting flat long components with precision using a CO2 laser. The original 3D printed model was posted several years ago, but this particular part is one of the front legs, showcasing its versatility and adaptability. Unfortunately, the work circle proves to be less than ideal for use with 0.5mm diameter muscle wire due to the presence of water in the sponge strip, which was cut using a CO2 laser from a discarded washing pad. Despite instant contraction, cooling is a slow process. To see this device in action, please refer to the accompanying video: https://youtu.be/hHddBv2kA48
