Medical Modelling and Rapid Prototyping are being used extensively to produce accurate implants. Rapid Prototyping has been used in making 3D medical models. The models help in personalizing pre-surgical treatment and pre-operative planning. Medical modelling is used for creation of high precision physical models from medical scans. The process includes collecting scans. The process includes collecting human anatomy data and optimizing the data for manufacturing and creating models using rapid prototyping. Computer aided software is used for prototyping. To produce high precision models, the modelling has to be in 3D. Therefore, a proper scanning method has to be used for each type of surgery. In this work we have taken a case study of fingers of hand to design and develop the 3D model for each case. We have designed, developed and fabricated one of the surgical guides for the fingers of hand. The design and fabrication was done in the 3D slicer and Grab CAD software independently. This work provides the approach and systematic procedure for the design and fabrication of surgical guide.
