Every October, Washington, D.C. becomes the center of the Army’s world. The AUSA Annual Meeting and Exposition runs October 12 to 14 at the Walter E. Washington Convention Center, drawing more than 44,000 attendees, over 750 exhibits, and delegations from 92 countries. It stands as the largest land power exposition in North America, and for three days it is where Army leadership, program offices, and defense industry set direction on modernization, sustainment, and readiness.
Underneath all of that sits a manufacturing problem. Every new vehicle, every replacement part for an aging fleet, every subsystem coming in for repair or upgrade needs someone who can build it, build it to spec, and build it on a schedule the mission can actually work around. That is a harder problem than it sounds.
The Manufacturing Problem Underneath It All
Defense, aerospace, marine, and energy programs share a set of pressures that traditional casting and forging were never designed to handle at speed. Lead times on a new casting can run past a year once tooling and mold work are factored in. Legacy components on platforms that have been in service for decades sometimes cannot be recast at all, because the original tooling is gone, the foundry closed, or the drawings never made it into digital form. Add a supply chain that increasingly depends on overseas casting houses, and a single disruption can stall a sustainment program for months.
At the same time, the materials involved carry little margin for error. Titanium components in an airframe, nickel alloy housings running at high temperature, corrosion resistant piping on a ship or an offshore platform: these parts are only useful if their mechanical properties hold up exactly where they need to, under the loads, temperatures, and environments they were designed for. Precision is not a nice to have in these sectors. It is the whole point.

Where Wire Based Metal Additive Manufacturing Fits
This is the gap Wire Arc Additive Manufacturing and Laser Wire Directed Energy Deposition were built to close. Both processes build metal parts layer by layer directly from a CAD model, which removes the tooling investment and the mold lead time that casting requires. A component that would take a year through a traditional foundry can move through design, printing, machining, and qualification in a matter of weeks.
That speed does not come at the cost of traceability. Wire based deposition is a controlled, monitored process, which means every layer of material can be logged and every finished part can be tied back to its build data, a requirement that matters as much to a defense quality standard as it does to an aerospace one. It also opens the door to reproducing parts that traditional manufacturing cannot touch anymore: components with no surviving tooling can be reverse engineered and rebuilt in a fraction of the time a new casting program would take.

One Roof, From Design to Qualification
Fastech was built around that opportunity. Our facility in Danville, Virginia is AS9100D and ISO 9001:2015 certified and ITAR registered, and it runs the manufacturing chain that matters for defense, aerospace, marine, and energy customers under one roof: design for additive manufacturing, Wire Arc and Laser Wire DED printing, 5-axis CNC machining, inspection, and qualification support.
Our printing floor combines two Gefertec Arc605 systems and an AML3D Arcemy X for large format, high deposition WAAM builds, alongside a Meltio M600 and Meltio Blue and Red Laser Robot Cells for LW-DED work. Fastech is the first Meltio Reference Site in the United States. On the machining side, 5-axis platforms including the GROB G350 and HERMLE C60 hold tolerances down to plus or minus 0.0005 inches, and our Mitutoyo CMM and Scantech KScan Magic metrology equipment support the reverse engineering, dimensional inspection, and qualification work that these industries require.

Solutions for Defense, Aerospace, and Energy
For defense sustainment programs, that means legacy castings and forgings that have become obsolete or unavailable can be reverse engineered and rebuilt in stainless steel, titanium, or high-nickel alloys, without waiting on a foundry that may no longer exist. For aerospace applications, Ti-6Al-4V gives engineers the strength to weight ratio airframe and engine components demand, while Inconel 718 covers structural parts that need to hold their properties at high temperature, all finished to tight tolerance on our 5-axis machining centers.
For marine and energy customers, CuNi 70/30 delivers the corrosion resistance that piping systems, condensers, and heat exchangers need in saltwater environments, and Alloy 625 and Stainless Steel 316L cover the chemical, oil and gas, and power generation applications where corrosion resistance has to hold up under sustained stress. In every case, the same in house path applies: a part moves from design through printing, machining, and inspection without changing hands between vendors, and the material and process data travel with it the whole way.

Meet Us at AUSA 2026
Fastech will be at the Virginia Economic Development Partnership pavilion, Hall A, Booth 167,, for all three days of AUSA 2026. If you have a legacy part stuck on a casting lead time, a new program that needs a domestic manufacturing partner, or a material and mechanical property question you have been sitting on, stop by.
Stop by Hall A, Booth 167 and let’s move your next project forward.
See you in Washington,
The Fastech Team
