Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting Technologies
Lawrence E Murr,Sara M. Gaytan,D. A. Ramirez,E. Martinez,Jennifer Hernandez,Krista Amato,P. W. Shindo,Francisco Medina,Ryan B. Wicker +8 more
TL;DR: In this paper, a comparative study of selective laser melting (SLM) and electron beam melting (EBM) is presented for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds.

Microstructures and mechanical behavior of Inconel 718 fabricated by selective laser melting
Krista Amato,Sara M. Gaytan,Lawrence E Murr,E. Martinez,P. W. Shindo,Jennifer Hernandez,S. Collins,Francisco Medina +7 more
TL;DR: In this paper, the Inconel 718 cylinders were fabricated by selective laser melting in either argon or nitrogen gas from a pre-alloyed powder, and they exhibited columnar grains and arrays of oblate ellipsoidal precipitates oriented in a strong [2.0.0] texture determined by combined optical metallography, transmission electron microscopy, and X-ray diffraction analysis.
Journal ArticleDOI
Microstructure and mechanical behavior of Ti-6Al-4V produced by rapid-layer manufacturing, for biomedical applications.
Lawrence E Murr,Stella Quinones,Sara M. Gaytan,M.I. Lopez,A. Rodela,E. Martinez,D.H. Hernandez,E. Martinez,Francisco Medina,Ryan B. Wicker +9 more
TL;DR: The microstructure and mechanical behavior of simple product geometries produced by layered manufacturing using the electron beam melting (EBM) process and the selective laser melting (SLM) process are compared with those characteristic of conventional wrought and cast products of Ti-6Al-4V.
Journal ArticleDOI
Next-generation biomedical implants using additive manufacturing of complex, cellular and functional mesh arrays
Lawrence E Murr,Sara M. Gaytan,Francisco Medina,H. Lopez,E. Martinez,B.I. Machado,D.H. Hernandez,L. Martinez,M.I. Lopez,Ryan B. Wicker,J. Bracke +10 more
TL;DR: Prospects for the manufacture of patient-specific biomedical implants replacing hard tissues (bone), particularly knee and hip stems and large bone (femoral) intramedullary rods, using additive manufacturing (AM) by electron beam melting (EBM) are examined.
