Additive manufacturing (AM), also known as three-dimensional (3D) printing, has boomed
over the last 30 years, and its use has accelerated during the last 5 years. AM is a materials …

We review the progress of additive manufacturing effort on refractory metal tungsten and
tungsten alloys. These materials are excellent candidates for a variety of high temperature …

There is considerable interest in the adoption of additive manufacturing for processing
refractory metals. The layer-wise fabrication approach enables opportunities for producing …

Additive manufacturing (AM) presents a new design paradigm for the manufacture of
engineering materials through the layer-by-layer approach combined with welding theory. In …

Material structure and defects created during additive manufacturing contribute to the
variability in mechanical properties of these parts, limiting their use for critical applications …

Electron beam freeform fabrication (EBF 3) has drawn increasing attention over the past
decade due to its potential for time and cost savings. The microstructure and mechanical …

Components made by laser powder bed fusion (L-PBF) additive processes require
extensive trial and error optimization to minimize defects and arrive at targeted …

Abstract Three-dimensional (3D) characterization provides opportunities for understanding
processing-structure relationships in additively manufactured (AM) materials. Bulk samples …

Defect-tolerant materials are good candidates to be produced by additive manufacturing as
parts often suffer from the presence of various kinds of defects: internal (pores) and …

Traditional design and qualification methodologies for parts manufactured by traditional
methods are being applied to Additive Manufacturing (AM) without understanding the …
