Design for X-Ray Computed Tomography

Procedia CIRP, 2019
Abstract The search for higher and higher performance is pushing part geometry to increased complexity. A significant contribution to this trend has been given by the diffusion of additive manufacturing technologies: substituting a simple additive manufacturing part with a complex one does not significantly affect the production cost.

Development of a Novel Processing Route for Dispersoid/Precipitation‐Strengthened High Conductive Copper Alloys by Using Metalized Nanoceramics in Additive Manufacturing

Advanced Engineering Materials, EarlyView.
This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.
