Scan It, Build It

When Gabe Draguicevich was asked to help fabricate a titanium hip implant based on CT (computed tomography, also known as CAT) scan data, he had to coordinate numerous technologies to complete the project. Because the CT data consisted of 2-D cross-sections, Draguicevich had to stack and align the individual scans to create a 3-D model, which he used to create a polygonal mesh in the form of a stereolithography (STL) file. After creating a prototype, he had to verify it against the original scan data, which was no mean feat considering that software capable of providing deviation analysis of the model surface to the STL file did not exist. Finally, Draguic...
