China3D printingNet, April 13th, the US Applied Science and Technology Research Organization (ASTRO America) has been selected to coordinate a new plan by the US Army that focuses on the development of super large metals for the production of ground vehicles.3D printingmachine.
The system is “seamlessCar bodyPart of the project, which will be used for tanks and Humvees3D printingSingle-piece armored vehicle body (chassis).According to ASTRO, the machine will be the world’s largest metal used in ground vehicle production3D printingIt will shorten the delivery time, significantly reduce the manufacturing cost and reduce the weight of the vehicle design.
ASTRO America principal researcher Larry Holmes (Larry Holmes) explained: “Our task is to develop a large-scale tool that can produce a single-bodied 30ft x 20ft x 12ft jointless combat vehicle as a whole. Large-scale additive Manufacturing has the potential to change the way military vehicles are manufactured, while reducing the fragility of the supply chain.”

The overall printing of the front line
Frontline combat vehicles must withstand all kinds of harsh conditions, including extreme weather and surprise attacks by opposing forces. In terms of survivability and weight reduction, the use of these monolithic hulls for these tanks can have major advantages, but traditional manufacturing processes have always struggled with this application. This is especially true when multiple vehicle models are involved, because technologies such as machining and metal injection molding are not built to achieve dynamic geometric flexibility at all.
This is3D printingThe use of this technology, because the technology can realize the previously impossible part design, thereby improving the performance of the fighter. In the case of parts production, additive manufacturing can also shorten delivery times, which is crucial for organizations such as the US Army, because it usually needs to dynamically adapt to high-risk situations within a limited time frame.
US Army Additive Manufacturing Engineer Aaron LaLonde added: “This project will extend the advantages of metal additive manufacturing to a certain size range, which will enable the advantages of this technology to be realized on larger system-scale parts, and Support next-generation car performance.”

Additive manufacturing in the armed forces
The “Seamless Carbody Project” managed by ASTRO America is contracted by LIFT, a national manufacturing innovation agency supported by the Department of Defense. In addition, the U.S. Army Combat Capability Development Command Ground Vehicle System Center (DEVCOM GVSC) will direct the technology plan, and the Army’s Iwashima Arsenal-Joint Manufacturing Technology Center will be used to house the new additive manufacturing platform.
“This is an ideal project for ASTRO America and its experienced team,” concluded Jason Gorey, Executive Director of ASTRO America. “This is not a research project for hardware, software or materials. This is a direct implementation project. We will extend the existing but advanced methods to the required hull size. We will work with equipment suppliers and system integrators to complete this project.”
At the end of last year, ASTRO America also completed research commissioned by the Defense Advanced Research Projects Agency (DARPA) to accelerate the development of hypersonic missiles.3D printing. This study details a comprehensive, end-to-end supersonic production accelerator facility (HPAF) design plan to integrate the entire supply chain under one roof.

Specifically, the plant will focus on using Titomic’s patented Kinetic Fusion (TKF)3D printingTechnology manufactures the weapon system barrel designed by Repkon.
