TL;DR: In this paper, the authors investigate the fabrication conditions that enable printing of single crystals via electron beam melting and find that the grain selection mechanism is independent of the bulk scale geometry and must therefore be driven by local heat transfer and solidification dynamics.

TL;DR: In this article, the use of near-infrared imaging was used to detect and quantify porosity in Ti-6Al-4V builds fabricated from different powder feedstocks and its correlation to their fatigue response.

TL;DR: In this paper, the authors evaluate the limitations of an existing commercial topology optimization software (i.e., Inspire®) using electron beam powder bed fusion (e.g., Arcam®) to produce optimized Ti-6Al-4V alloy components.

TL;DR: In this paper, the role of geometry and beam path sequencing in a powder bed electron beam melting process is investigated, and it is observed that by carefully engineering the melting sequence the morphology and texture at the mesoscale can be controlled.

TL;DR: In this article, the effects of overlooked variables such as melt order and nested geometry on the distribution of defects and bulk material properties in Ti-6Al-4'V alloy builds manufactured using the Arcam AB ® electron beam powder bed fusion process were investigated.
