Fabrication of titanium components by Laser Powder Deposition (LPD) offers some unique solutions for high performance aerospace applications. LPD is a CAD/CAM solid freeform fabrication technology that uses metal powder and laser fusion to produce components. This paper describes the mechanical property and metallurgical results obtained from LPD titanium structures as well as the parameters required to produce them. Some examples of titanium fabrications and repairs are provided. LPD’s unique capabilities allow direct fabrication of titanium components with design features that are difficult or expensive to obtain by other technologies.
Summary: Fabrication of titanium components by Laser Powder Deposition (LPD) offers some unique solutions for high performance aerospace applications.
