Najeb Jamaludin, supervisor Biomedical engineering and health science Also available in printed version Prosthetic hand is a device that is designed to provide and replace the function of human hand for those who had lost their upper limb. At the moment, there is a lot of prosthetic hand with various design and mechanism such as body powered prosthetic hand. However, those prosthetic hands are very difficult to get full satisfaction of consumers due to certain limitation. Therefore, the purpose of this study is to develop a hydraulic mechanism for 3D printed prosthetic finger with linear motor control and to evaluate the range of motion of the prosthetic finger joint. This study required step by step process starting form sketching, Computer Aided Design (CAD), Fused Deposition Modeling (FDM), prototype assembly, implementation of control circuit and coding, and lastly evaluation of range of motion. The prosthetic finger is designed in Autodesk Fusion 360 software and the prototype is printed by using Zortrax M200 FDM printer. The FDM printer uses a thermoplastic filament known as Acrylonitrile Butadiene Styrene (ABS) that is heated to its melting point and then extruded layer by layer in order to create a three dimensional object. Two prototypes were made, without spring and with spring. The prototype comprised of 3D printing material, Terumo 1ml syringe, capillary silicone tube 0.5mm of inner diameter, gear DC motor, nut and 40mm Allen cap screw. The materials used for control circuit are SAMD21 Mini Breakout board, L293D and 3.7V 18650 Lithium-ion rechargeable battery. The range of motion of the prosthetic finger joint was evaluated for 30 cycles by using a protractor. First, the range of motion of finger joint for prototype without spring was analyzed and it shows poor data. Then, the range of motion of finger joint for prototype with spring was analyzed in order to improve the data. The mean values of range of motion of Metacarpophalangeal (MCP) joint for prototype without spring and with spring are 66.47? and 76.22? respectively. While the mean values of range of motion of Proximal Interphalangeal (PIP) joint for prototype without spring and with spring are 55.63? and 77.8? respectively. In conclusion, hydraulic mechanism has been designed for 3D printed finger and the range of motion is acceptable and there is more room for improvement. zainurin UTM 115 p.
