Abstract
The advantages of additive manufacturing of metal components through laser-based powder bed fusion of metals (PBF-LB/M) have been increasingly embraced across a variety of industries and applications. But, broader adoption of this manufacturing technology requires that computational models and in-situ monitoring of such processes be experimentally validated under highly controlled conditions with advanced metrology. Such validation of models and in-situ monitoring systems are especially important for critical for applications that require qualification and certification. Such controlled conditions and advanced metrology cannot be readily implemented in commercial PBF-LB/M machines due to a variety of constraints and unknowns about machine performance. Therefore, a laboratory testbed has been develop to study the Fundamentals of Laser-Matter Interaction (FLaMI) at NIST. This paper outlines the materials and methods to develop such a system, as well as to accurately calibrate and characterize the machine performance.Citation
