Abstract

The purpose of this project is to design a hand and wrist support device by using Reverse Engineering ( RE ) methods and Additive Manufacturing ( AM ) process . The goal of this project is to produce hand and wrist support device to improve ergonomics and comfort to patients. This project focuses on the design of a prototype tool based on the geometry of the hand and wrist support for patients and types of injuries sustained. Mostly, the tools available to support the hand and wrist , especially for patients suffering from severe injuries such as fractures or cracks have standard size according to their age but when suffering severe injuries such as fracture hand and wrist still using plaster of paris which makes it difficult for the movement to make a thing . However, users will feel uncomfortable. An initial survey was conducted through a questionnaire for early response on hand and wrist support device. Software with can facilitate data and redesign the hand and wrist support device need to used and some of them are Geomagic Studio 10 software and Solidwork 2013. For the scanning process, Faro Arm is used to get hand shapes using fake statue and hand shape made of hand wax. Then the hand and wrist support device that has been produced by Solidwork will be sent to the Fused Deposition Modeling (FDM) machine to produce a prototype. The next process is drawing need to analyzed using Solidwork simulation, the results of the analysis indicate that the design pressure of the hand and wrist support FDM produced parts are safe to use based on the safety factor is higher than I.
