Optomec has announced an advancement in capability for the company’s LENS Directed Energy Deposition (DED) systems relative to AM and repair of aluminum alloys. This innovation can be used to deposit any aluminum alloy, including those recently developed specifically for improved properties with AM processing, the company says.
This development for the Optomec DED process opens the transportation and aerospace industries to AM and repair of complex aluminum alloy parts using powder-based DED. Additionally, the use of Optomec’s LENS simultaneous five-axis system enables the processing of aluminum alloy parts with complex geometries without the need for support structures. Deposition of aluminum alloys in a controlled atmosphere glove-box with very low levels of oxygen and moisture ensures achievement of components with superior mechanical properties.
David Otazu, LENS Applications Engineer states, “Our engineers have developed process parameters for aluminum alloys to provide an excellent surface finish, high deposition rates and a density of ~99.9%.” With this advancement, Optomec LENS systems can successfully process all common materials used for AM including Steels, Titanium, Nickel, Copper, and now, Aluminum.
Additive Manufacturing’s Field of Dreams: GE’s new Customer Experience Center aims to accelerate AM’s adoption around the world.
High-end metal additive manufacturing relies on the perfect gas composition to create products that meet the required material properties. But gas such as argon is also key to metal powder production, storage and postprocessing.
GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
