X-ray Tomography Characterisation of Lattice Structures Processed by Selective Electron Beam Melting

Metals, 2017
Metallic lattice structures intentionally contain open porosity; however, they can also contain unwanted closed porosity within the structural members. The entrained porosity and defects within three different geometries of Ti-6Al-4V lattices, fabricated

Fabrication of Single Crystals through a µ-Helix Grain Selection Process during Electron Beam Metal Additive Manufacturing

Metals, 2020
Selective Electron Beam Melting (SEBM) is a powder bed-based additive manufacturing process for metals. As the electron beam can be moved inertia-free by electromagnetic lenses, the solidification conditions can be deliberately adjusted within the ...

A Comparative Study on Selective Laser Melting and Electron Beam Melting Process for Orthopedic Implants [PDF]

Proceedings of the 1st International Conference on Progress in Additive Manufacturing, 2014
Selective laser melting and electron beam melting are two metal additive manufacturing processes which gained considerable attention in the recent years. These techniques allow large degree of freedom in design such that complicated geometries can be manufactured with higher accuracy and efficient use of materials.
