Rapid prototyping technology is widely used to fabricate 3-D objects with all features of a design using Computer Aided Design (CAD) model. The final fabricated object with rapid prototyping technique has to be evaluated regarding the extent of its closeness to CAD model. Geometric conformity analysis has to be used in determining a measure of the geometric deviation between designed and fabricated 3-D models. In this paper evaluation technique is used to provide an aggregate measure of overall geometric deviation between designed free formed surface and its fabricated geometries using Fused Deposition Modeling (FDM) technique. This approach is typically utilized for large or more complex assemblies such as vehicle interiors and exteriors and full scale aircraft etc. Computer Aided Inspection with CMM aims at development of suitable methodology so as to convert data obtained from CMM to convenient formats to measure dimensional and form errors of freeform surface objects. The present work used in additive manufacturing with the newer methodology of inspecting in rapid product development also.
