Additive Manufacturing: Current State, Future Potential, Gaps and Needs, and Recommendations

TL;DR: Additive manufacturing (AM) is the process of joining materials to make objects from 3D model data, usually layer by layer, is distinctly a different form and has many advantages over traditional manufacturing processes.
Book ChapterDOI

Measurement science needs for real-time control of additive manufacturing powder-bed fusion processes

TL;DR: In this paper, the authors present a review on the AM control schemes, process measurements, and modeling and simulation methods as it applies to the powder bed fusion (PBF) process, though results from other processes are reviewed where applicable.
Journal ArticleDOI

Laser powder bed fusion of nickel alloy 625: Experimental investigations of effects of process parameters on melt pool size and shape with spatter analysis

TL;DR: In this article, the effects of process parameters and scan strategy on the relative density, melt pool size and shape were investigated for powder material nickel-based alloy 625, which is one of the choice of metal materials for fabricating components in jet engines and gas turbines due to its high strength at elevated temperatures.
Journal ArticleDOI

Geometrical metrology for metal additive manufacturing

TL;DR: The infrastructure under development for specification standards in AM is presented, and the research on geometrical dimensioning and tolerancing for AM is reviewed, and post-process metrology is covered, including the measurement of surface form, texture and internal features.
Journal ArticleDOI

Influence of scan strategy and process parameters on microstructure and its optimization in additively manufactured nickel alloy 625 via laser powder bed fusion

TL;DR: In this paper, the effects of process parameters including laser power, scan velocity, hatch distance, and scan strategy that produce various solidification cooling rates and thermal gradients during the process, which also contribute to the resultant microstructure, have been analyzed.
