U.S. Marines Complete EOS Metal 3D Printing Expeditionary Repair Exercise at Camp Pendleton: Over 200 Parts Produced in a Single Print Run

2026-08-22 · Impact score: 24

According to media reports on August 22, 2026, the U.S. Marine Corps' 1st Maintenance Battalion, in partnership with Phillips Federal, completed a two-week expeditionary additive manufacturing repair exercise at Camp Pendleton, California, validating on-site MRO capabilities under simulated forward-deployed austere conditions. The system suite included an EOS M290 metal laser powder bed fusion (LPBF) system, an EOS P3 polymer powder bed system, and hybrid DED equipment, all integrated with the 3YOURMIND manufacturing execution system. During the exercise, the polymer powder bed system produced over 200 parts in a single run, challenging the conventional notion that laser powder bed technology is "not suitable for deployment." This model targets on-site repair in logistics-disrupted environments, directly supporting supply chain resilience requirements under Section 849 of the U.S. National Defense Authorization Act (NDAA), providing a military-grade reference for the use of metal powders in forward repair scenarios. The U.S. military is systematically advancing the concept of "expeditionary manufacturing," extending from depot-level repairs at home bases to point-of-need fabrication at the tactical edge. The deployment of metal LPBF systems with forward units means that powder storage, recovery, sieving, and quality control at forward bases become critical operational needs, opening a new niche market for powder suppliers as a "deployed supply chain." Value proposition for powder buyers: ① Forward-deployed scenarios require highly flowable, low-oxygen, multi-recyclable powders such as 316L, TC4, and IN625, with rising demand for powder recovery and sieving services; ② Suppliers with moisture-proof vacuum packaging, batch traceability, and familiarity with U.S. military material specifications can secure a foothold in the deployed supply chain; ③ If this model expands across multiple service branches, it will drive small-batch, multi-grade, high-frequency replenishment purchasing patterns, and domestic (Chinese) suppliers should monitor opportunities for export support at overseas bases.

Amaero Expands U.S. Metal Powder Capacity: Three EIGA Atomizers at Full Production, FY26 Revenue Surges 376%

On August 22, 2026, U.S. metal powder manufacturer Amaero (ASX: 3DA) announced the early commissioning of its third electrode induction gas atomization (EIGA) system at its McDonald, Tennessee facility. This brings the plant's annual capacity to 480 metric tons of titanium alloy powder and 200 metric tons of refractory alloy powder, totaling 680 metric tons per year—making Amaero the largest domestic U.S. supplier of spherical titanium and refractory metal powders. The product portfolio includes specialty grades such as C103 niobium-based powder for rocket engines and hypersonic applications. The company reported a 376% year-over-year increase in FY2026 revenue, with a backlog of AUD 23 million. Its three-year, AUD 72 million capital expenditure plan was completed on schedule, and Amaero has indicated it is considering a U.S. listing between late 2026 and early 2027. The capacity expansion is closely tied to the Pentagon's domestic supply chain strategy (DFARS compliance), underscoring the strong pull of defense demand on metal powder localization. The U.S. defense supply chain 'de-risking' policy continues to intensify, with domestic titanium and refractory powders designated as critical materials. Beyond Amaero, U.S. producers such as ATI and IperionX are also expanding capacity. The global spherical titanium powder supply landscape is shifting from a China-export-dominated model toward multi-polar localization, creating competitive pressure on Chinese powder suppliers' export volumes and premium-grade pricing. Key takeaways for powder buyers: ① With expanded domestic U.S. capacity for titanium alloy spherical powder and C103 niobium-based powder, buyers in U.S.-linked supply chains can source from DFARS-compliant local suppliers to shorten lead times. ② Chinese powder manufacturers can benchmark Amaero's refractory alloy (niobium-, tantalum-, and tungsten-based) product lines—a segment with high unit prices and lower competitive density. ③ Monitor Amaero's U.S. IPO progress; a successful listing could accelerate its expansion and further erode Chinese titanium powder's share in the North American market.

Deep Blue Aerospace's 'Thunder-RS' 130-Ton Engine Successfully Completes 100-Second Long-Duration Test; Over 85% of Components 3D-Printed

On August 21, 2026, Deep Blue Aerospace announced that its 'Thunder-RS' liquid oxygen kerosene engine completed a 100-second long-duration hot-fire test at its test facility, achieving a measured thrust of 1297.5 kN (approximately 132.3 tons-force) with zero anomalies throughout, marking the first time it has crossed the 100-second steady-state threshold. This engine is the largest-thrust gas generator cycle pintle injector liquid oxygen kerosene engine in China, with over 85% of its components manufactured as single-piece structures via metal 3D printing. The Thunder-RS serves as the primary propulsion system for the large reusable rocket 'Nebula-2', with 11 engines clustered in the first stage, providing a low Earth orbit payload capacity of 25 tons, with its maiden flight planned for 2027. The engine was assembled and delivered at the Wuxi High-tech Zone, and it took only a few months from the initial complete engine rollout to the completion of the long-duration test. The long-duration test is a prerequisite for validating the 11-engine cluster and vertical recovery. Successfully passing the 100-second steady-state threshold marks the engine's entry into the engineering maturity phase. The application of metal 3D printing in rocket engines is transitioning from demonstrative validation to batch production engineering. The single-piece manufacturing of core components such as combustion chambers, injectors, and turbopumps can significantly reduce weight and shorten manufacturing cycles. Domestic commercial aerospace companies (including LandSpace, Space Pioneer, and iSpace) are fully adopting this approach, directly driving up the bulk procurement demand for high-temperature alloys, copper alloys, and titanium alloy spherical powders. Value for powder purchasers: ① The increasing volume of 3D-printed components in commercial aerospace engines boosts demand for GH4169/IN718-type high-temperature alloy powders, CuCrZr copper alloy powders, and TC4 titanium powders, with the laser powder bed fusion (LPBF) process using 15-53μm particle size ranges being the primary application; ② Engine manufacturers impose high requirements on powder batch consistency and aerospace-grade quality system certification, so powder suppliers capable of providing stable batch-to-batch supply will gain priority access to the supply chain; ③ Monitor the upcoming 11-engine cluster test milestones for Nebula-2, as the period before the 2027 maiden flight is a critical window for powder sample submission and qualification.
