Arms Dealer Installs DED Metal 3D Printer for Aircraft Parts

Argo 1000 HyperMelt System

Argo 1000 HyperMelt is a third-generation directed energy deposition (DED) device launched by Additive Works, a supplier of metal 3D printing technology. Its core advantages lie in its high deposition rate and large-size component manufacturing capabilities:

Build range: The maximum processable part size is 1000×1000×1200 mm.

Deposition rate: The printing speed of titanium alloy materials can reach 8-10 kg per hour, which is 5-8 times that of the conventional LPBF process, greatly shortening the production cycle of large parts.

Energy system: It uses a 4-kilowatt fiber laser (upgradeable to 6 kilowatts) and dynamic spot control technology to adjust energy output in real time according to the part structure, balancing efficiency and precision.

Multi-axis linkage: Equipped with a 6-axis robot arm and a rotary workbench, it supports the integrated processing of complex curved surfaces, hollow structures and repair parts, reducing the amount of subsequent machining.

Material adaptability: compatible with commonly used aerospace metals such as titanium alloy (Ti-6Al-4V), nickel-chromium alloy (Inconel 718), stainless steel (316L), and supports composite printing of dissimilar materials.

The system also integrates an online quality monitoring module, which captures the temperature distribution of the molten pool and the interlayer size deviation in real time through infrared thermal imaging and laser scanning. The data can be synchronized to the MES system for full traceability.

Application scenarios and strategic value

CRG Defense is a first-tier supplier certified by the US military, focusing on producing complex metal parts for equipment such as F-35 fighters and V-22 Osprey helicopters. The introduction of Argo 1000 HyperMelt is mainly aimed at three major application directions:

1. Direct manufacturing of large structural parts: such as drone fuselage frames and missile compartments. Traditional forging requires large molds, while 3D printing can achieve near-net forming, and the material utilization rate is increased from 10-15% of traditional processes to more than 80%.

2. Repair of old equipment parts: For some discontinued active equipment (such as the B-52 bomber), reverse engineering scans the worn parts and uses DED technology to directly clad new materials on the substrate to restore dimensional accuracy and extend service life.

3. Lightweight composite structure research and development: Combined with topological optimization design, honeycomb, grid and other bionic structural parts are manufactured to reduce weight by 30-50% while ensuring strength, adapting to the weight reduction needs of the new generation of military aircraft.

Mike Reynolds, CTO of CRG Defense, said: "HyperMelt technology has redefined our expectations for the efficiency of metal additive manufacturing. For example, a helicopter transmission shaft bracket requires 12 weeks of traditional forging and machining, while Argo 1000 only takes 5 days to complete near-net shape, and the fatigue strength of the part is increased by 15%. This not only shortens the delivery cycle to the military, but also allows us to respond quickly to design iteration needs."

Supply Chain and Partner Collaboration

As an equipment supplier, Additive Works will provide CRG with 3 years of technical support, including process development, operator training and material parameter optimization. The company's CEO Eva Kovacs pointed out: "The core challenge of aerospace manufacturing is the balance between reliability and efficiency. HyperMelt's dynamic energy control technology ensures the stability of each layer of the molten pool, and its process repeatability has been certified by NADCAP (Aerospace Quality Management System), which is also the key to CRG's choice of cooperation with us."

In addition, CRG has also reached a cooperation with ATI, a supplier of special metal materials, to jointly develop low-cost titanium alloy powders suitable for the HyperMelt system. By optimizing the powder particle size distribution and fluidity, the deposition efficiency and part density can be further improved.

Brian Gomez, director of the Advanced Manufacturing Department of the U.S. Air Force Research Laboratory (AFRL), commented: "Suppliers like CRG embrace DED technology, which is an important step in the implementation of the Department of Defense's 'agile manufacturing' strategy. When the battlefield needs to replace parts, we can no longer rely on the long supply chain of transcontinental transportation-localized, fast-response 3D printing capabilities will become the core competitiveness of future combat support."

Industry impact and future planning

CRG plans to deploy two more Argo 1000 systems in the next 18 months to build a large-scale DED production unit and apply to become a partner of the U.S. Department of Defense's "Additive Manufacturing Center of Excellence". Reynolds added: "Our goal is to integrate HyperMelt technology into the military's 'digital thread' system - from design files to finished parts, to achieve full process digitization and support the 'on-demand production' logistics model."

Industry analysts believe that CRG's layout reflects two major trends in aerospace manufacturing: one is that large-scale DED equipment is shifting from "prototype development" to "mass production", and the other is that defense companies are paying more and more attention to the improvement of supply chain resilience by additive manufacturing. As the technology matures, it is expected that by 2027, 20% of the metal parts purchased by the US military will be produced by high-speed 3D printing technology similar to HyperMelt.

Notice: The Second 3D Printing Farm Conference

On August 26-28, 2025, the second 3D Printing Farm Conference jointly organized by Antarctic Bear and Formnext Asia Shenzhen Exhibition will be grandly opened. As one of the most representative additive manufacturing ecological exhibitions in China, this conference will once again bring together material suppliers, equipment suppliers and farmers to fully present the cutting-edge practices and future directions of the 3D printing farm ecology.
