Title: Variability in the Geometric Accuracy of Additively Manufactured Test Parts
Published: August 09, 2010
Abstract: Results of a study on the variability in the geometric accuracy of a metal test part manufactured by several service providers using either electron beam or laser based powder bed thermal fusion processes are described. The part was a circle-diamond-square with an inverted cone that is used to evaluate the performance of five-axis milling machines. The study was conducted to aid development of standardized parameters and test methods to specify and validate the performance of additive manufacturing systems. Without such performance evaluation standards, it is difficult to match system capabilities with part requirements and ensure consistent part quality across systems, operators, and manufacturing facilities.
