Research on the fabrication method of custom artificial bone based on reverse engineering

Two kinds of new fabrication methods have been proposed and realized in order to reconstruct geometric shape of human's bones, which is very difficult to traditional mechanical methods. The two methods are interpolation and surface-reconstruction. According to patient's computer tomography (CT) and magnetic resonance imaging (MRI) data, custom artificial bones can be fabricated by using image-processing, reverse engineering and rapid prototyping technology. Two examples have been implemented by these methods. It is validated that the new fabrication methods have the advantages, such as shape-matching, shorter manufacture period and low-cost.
