Ergonomic design of handle using rapid prototyping technology

This paper describes a practical and simple approach to designing ergonomic handles using software for 3D design and equipment for rapid prototyping. The new technologies reduce costs and allow manufacturing of ergonomic parts in short period of time. The feasibility of this approach was verified with the development of custom made ergonomic handle for wheelchair. The handle was designed using a hand-grip impression in the clay model. After acquiring a hand-grip impression the model was digitized with Steinbichler Comet5 3D scanner. CAD model of the ergonomic handle was designed upon on the cross - sections obtained from the .stl scanner file. The prototype for assessment was built on the ZCorp 3D printer.
