Laser metal deposition in-situ process control for different build strategies

Quality assurance is a key factor for industry adoption of additive manufacturing (AM) technologies. The implementation of in-situ process controls for AM processes is crucial for achieving consistent quality AM components. This paper explores the control measures required to attain Laser Metal D...
