The following chapter represents the current state of literature on the selected additive manufacturing technologies and was written with an emphasis on quality control and material performance repeatability. Research and standards published by government entities such as the National Institute of Standards and Technology (NIST) and Department of Energy (DOE) have been included where applicable. It is recommended that literature be reviewed, and new knowledge integrated no less frequently than every four years due to the rapid pace of advancements in additive manufacturing and associated industries. AM presents unique challenges in certification for NPP applications such as anisotropic material properties, porosity, underdeveloped process control feedback systems, and reproducibility. This chapter begins with an overview of the selected AM technologies, followed by a systematic review of literature to detail the fabrication process and difficulties with repeatably fabricating fully dense, geometrically accurate components with known material properties.
