Electron beam melting (EBM) is a representative powder-bed fusion additive manufacturing
technology, which is suitable for producing near-net-shape metallic components with …

X-ray tomography has emerged as a uniquely powerful and non-destructive tool to analyze
defects in additive manufacturing. Defects include unintended porosity, rough surfaces and …

Metal additive manufacturing (AM) is an innovative manufacturing technique that can build
complex and high value metal parts layer by layer using a computerized three‐dimensional …

A key challenge in metal additive manufacturing is the prevalence of defects, such as
discontinuities within the part (eg, porosity). The objective of this work is to monitor porosity …

Additive manufacturing (AM) has the potential to revolutionize manufacturing because it can
fabricate complex geometries that are not possible with conventional manufacturing …

Computed tomography (CT) magnifies the spectrum of measurable internal features with
minimal preparation and exceptional resolution. In this study, non-destructive nano-scale …

Mechanical properties of additively manufactured parts are sensitive to the presence of
pores form during the manufacturing process. The impact of pores on the mechanical …

In the present review, the effect of porosity on the mechanical properties of the fabricated
parts, which are additively manufactured by powder bed fusion and filament extrusion-based …

The porosity observed in additively manufactured (AM) parts is a potential concern for
components intended to undergo high-cycle fatigue without post-processing to remove such …

Pore structures of additively manufactured metal parts were investigated with X-ray
Computed Tomography (XCT). Disks made of a cobalt-chrome alloy were produced using …
