Investigation of Discharge Characteristics of Hinges Produced with 3D Printing for Prosthetic Fingers

Flexible hinges are joint mechanisms made of soft or flexible materials. The aim this study is to determine the discharge characteristics used in prosthetic hands and fingers according production techniques most appropriate hinge parameters. speed opening process energy consumption during closing directly depend on structure hinge. For reason, it important examine relationship between change its terms oscillation requirement. In method study, primarily samples produced using different printing next step, a finger-like test system designed that uses accelerometers measure oscillations fingers. mechanism has body free accelerometer. sensor distinguish vibrations transmitted As result measurements with system, observed honeycomb shape higher frequency than linear filling shape. This indicates filler can store amount as stretching. percentage inner fill number outer shells increased, vibration when released found be higher. It been concluded hinge, which highest storage capacity at lowest cost, will have shape, 30% filler, four shells. Finally, measures power consumed for finger operations presented. levels hinges, increases infill density shell values increase. seen these compatible values. With aimed parameter selection robotic application planned by 3D future.
