Progress in Additive Manufacturing

High-density crack-free Inconel 738 samples were manufactured into both thin-walled and bulk samples using pulsed laser powder bed fusion (P-LPBF). As-built thin-walled samples presented a dendritic microstructure with primary dendrite arm spacing …

Fused filament fabrication (FFF) technology has been a cost-effective option in the additive manufacturing industry. It, however, still faces drawbacks in terms of tolerance, accuracy, surface finish and material property anisotropy that prevent …

In laser powder-bed fusion (LPBF), the actual thickness of powder particles that spread on solidified zones, so-called effective layer thickness (ELT), is higher than the nominal layer thickness. The source cause of this discrepancy is the fact …

One of the main challenges for the aerospace industry nowadays lies in weight reduction of aircraft components without compromising their structural functionalities. With that goal, structural and topology optimization show up as a combination of …

This paper deals with the production and experimental investigation of very thin aluminium 1050 grade foil products. Single lap joints and samples for flexural testing were made using composite metal foil manufacturing (CMFM) using a special …
