Alignment based inspection framework for additive manufactured parts

Abstract

Currently, Additive manufacturing (AM) processes do fabrication of parts having custom-made intricate profiles. It becomes an essential task to verify the accuracy of AM parts to meet customer’s need and requirement. Effective measurement and quick inspection of geometric data, performed by implementing reverse engineering in coalition with additive manufacturing. This paper proposes a novel framework for measurement and verification of overall accuracy of the additive manufactured parts. Present method integrates additive manufacturing along with 3D scanner and reverse engineering hierarchy for its implementation. For effective inspection, suitable alignment technique for individual features and GD & T attributes reported. With its simplicity, speedy inspection and accurate results this method will be helpful for manufacturers to increase their competitiveness in global market.
