The FY26 Defense Bill Just Elevated 3D Printing to a Pillar of National Defense

By Andrew Park | 2025-12-19

President Trump signed the annual defense bill (FY26 NDAA) into law today, December 18, 2025, ending 3D printing's status as an "experiment" and making it a requirement. The legislation mandates that the Department qualify 1 million part designs for 3D printing by 2027, a direct response to a vulnerability that's been quietly devastating America's military readiness. Over the past decade in U.S. war games against China, the United States has lost almost every single time [1]. One of the biggest reasons for these losses is our inability to sustain production in a high-intensity conflict. While America has the world's most advanced military systems, China has built a massive manufacturing capacity advantage that allows them to replace losses faster than we can. The FY26 NDAA directly addresses this by mandating the development of advanced manufacturing that can rapidly produce replacement equipment and munitions in the event of conflict. This isn't just about innovation; it's about ensuring America can sustain a fight.

The Strategic Reality: Why 3D Printing is Essential

We've got the best military tech, but we've fallen behind in how much we can build. China has linked its civilian and military factories so they can produce gear at a scale we just can't match. While we have the most powerful military, we lack "mass." For decades, the U.S. has focused on building "exquisite" systems: platforms like the F-35 or Ford-class carriers that are incredibly capable but also extremely expensive, complex, and time-consuming to build. The reality of modern high-intensity conflict is that these few, high-end assets are vulnerable to being overwhelmed by sheer volume.

China's ability to build ships is over 232 times larger than ours [2]. Experts warn that in a real conflict, we would likely run out of long-range missiles in less than one week [3]. Because we can't build hundreds of huge new factories overnight, Congress and the Department are betting on 3D printing. It gives us "strategic depth," which is the ability to print what we need, right where we need it, without needing a giant, easy-to-hit factory.

The Rise of the American Microfactory

One of the most exciting parts of this shift is that new American factories don't have to look like the giant plants of the past. 3D printing is enabling the rise of the "microfactory": a highly automated, small-scale production unit that can be placed almost anywhere. These factories are shrinking because 3D printers don't need massive floor space for specialized molds; a single machine can print thousands of different parts just by changing a digital file. They can often print a part that used to be 50 pieces as one single piece, getting rid of long assembly lines. And because microfactories print only what's needed on demand, they can cut their footprint by 50% to 70% by removing the need for giant warehouses.

Five Big Changes and the Companies Leading the Way

1. The Digital Warehouse Mission

Section 220A of the bill tells the Department to qualify and approve at least 1 million different part designs for 3D printing by the end of 2027 [4]. The goal is to build a massive digital library so a sailor or soldier can pull up a file and hit "print." 3D Systems Corporation and Stratasys Industrial are the frontrunners here because they already have huge libraries of flight-certified designs. Velo3D is also key for printing complex metal designs.

2. The Trojan Horse Problem

Section 880 of the bill stops the Department from using 3D printing machines made in China, Russia, Iran, or North Korea [4]. This prevents "kill switches" or digital sabotage. The practical effect is that all the market share that previously went to foreign manufacturers now comes home to American companies.

3. Building Drones at Home

The bill includes significant funding for small drones, and by September 2026, the Department must ensure at least 25% to 100% of these parts are 3D printed in the USA [4]. Firestorm Labs is positioned for this with their "xCell" system. Traditional giants like AeroVironment are also rapidly shifting to 3D printing to meet these rules.

4. Mobile Factories for Forward Operations

The bill focuses on deployable manufacturing cells: 3D printing hubs in a box that fit inside a standard shipping container [5, 7]. For the Navy, these units solve a critical problem: ships can be at sea for months, thousands of miles from the nearest supply depot. A 2024 Government Accountability Office report found that Navy ships routinely leave port already lacking 35 percent of required spare parts [8]. A broken part that would normally ground a mission can now be printed onboard within hours.

For the United States Air Force, these same mobile units are a game-changer for Agile Combat Employment (ACE). ACE requires jets to operate from small, remote forward bases to avoid being targeted at major hubs. These mobile units allow small teams of Multi-Capable Airmen (MCA) to print critical aircraft parts and specialized tools right at the tactical edge. This empowers a three-person team to keep a $100 million jet flight-ready without waiting weeks for parts to be flown in from across the globe [6].

Solideon is a standout with robotic microfactories that build large structural parts autonomously. SPEE3D is a favorite for expeditionary forces because their machines use high-speed metal spraying to fix heavy equipment and aircraft in minutes, even in harsh outdoor environments [7].

5. Cutting Red Tape for Speed

The bill streamlines the acquisition process, making it easier and faster to get innovative manufacturing solutions into the hands of warfighters. Nano Dimension is a leader here, focusing on 3D printing high-performance electronics and circuit boards on demand.

Today's Leaders: Building Blocks for Tomorrow's Ecosystem

While many companies can print a simple bracket, only a few currently have the security certifications, materials libraries, and proven track records to work within the defense ecosystem. These companies represent the foundation of America's 3D printing industrial base, but they alone can't close the manufacturing gap with China. The FY26 NDAA is designed to catalyze a much broader ecosystem.

Nano Dimension (NASDAQ: NNDM) Electronics Printing Capability Their DragonFly systems can 3D print high-performance electronics and circuit boards on demand, a capability few others possess. By acquiring Markforged in April 2025, they also gained ISO 27001 security certification needed for classified programs. They've been a certified Department vendor since 2018, though specific contract values remain undisclosed.

3D Systems Corporation (NYSE: DDD) Flight Certified Materials Library With decades of flight-certified data, their library of pre-approved materials and designs positions them for the million-part qualification mission. Recent Department contracts include a $10.8 million Air Force award in 2023 and a $7.65 million follow-on contract in August 2025 for large-format metal 3D printing to support hypersonic applications.

Stratasys (NASDAQ: SSYS) Largest Military Install Base They secured a $20 million U.S. Navy contract in 2021 for up to 25 F900 3D printers over five years, their largest government contract to date. Stratasys printers are deployed across Navy bases in the U.S. and Japan, and they've worked with Boeing, Northrop Grumman, and Naval Air Systems Command (NAVAIR) to qualify advanced materials for defense applications. In November 2025, Stratasys participated in Trident Warrior 25, the Navy's flagship Fleet experimentation exercise, supporting the Department's largest distributed manufacturing demonstration to date, connecting assets across more than 8,000 miles.

Velo3D (NASDAQ: VLDX) Specialized Metal Printing Their proprietary "SupportFree" technology enables printing of complex internal geometries for rocket engines and hypersonic applications that other metal printers can't reliably produce. In June 2025, Velo3D signed a four-year CRADA with NAVAIR to advance metal additive manufacturing for military flight hardware. The company also participates in a U.S. Army initiative developing qualification frameworks to enable distributed manufacturing across the Department.

Solideon (Private) Autonomous Large Scale Production Their robotic microfactories can build large structural parts autonomously, addressing the need for high-speed, low-labor manufacturing to meet aggressive onshoring mandates. In May 2025, Solideon was awarded a $1.25 million Direct-to-Phase II SBIR contract from AFWERX to develop a single-pallet additive manufacturing cell designed to fabricate critical systems in expeditionary environments for the U.S. Air Force.

SPEE3D (Private) Battlefield Repair Capability Using high-speed cold spray technology, SPEE3D supplied seven WarpSPEE3D printers to Ukraine through a U.S. Department contract in 2023, with additional systems deployed in 2024. Their technology can repair heavy equipment in minutes under combat conditions, a capability traditional printers can't match.

Expanding the Ecosystem: Opening the Door for New Vendors

The FY26 NDAA restructures how the Department buys additive manufacturing. The bill raises accounting thresholds so small companies can win multi-million dollar contracts without massive compliance departments, and requires buying proven commercial technologies instead of expensive custom military specifications.[4] The law prevents vendor lock-in by requiring portable Technical Data Packages (TDPs), so if Company A qualifies a part design, Company B can print it too. The Department isn't picking winners; it's building a competitive marketplace where the digital design is the strategic asset.

By making 3D printing mission-critical infrastructure, the legislation signals to venture capitalists that this space is worth investing in. Companies like Supernova Defense & Space, which secured a $2 million Department contract in January 2025 to 3D print military-grade explosives and rocket propellants, represent the type of new entrant this legislation aims to attract and scale.

Conclusion: The Right Move, Not the Whole Solution

The FY26 NDAA elevates 3D printing to a pillar of national defense, and our nation's leaders are right to do so. By mandating the qualification of 1 million part designs by 2027, banning adversary-nation manufacturing equipment, and restructuring procurement to favor commercial solutions, Congress has created the conditions for genuine transformation.

China's manufacturing advantage is staggering: 31% of global output today, projected to reach 45% by 2030 while the U.S. falls to 11%. Their 232 to 1 shipbuilding advantage and our vulnerability to running out of critical munitions in days expose the reality that we can't match their scale with traditional manufacturing alone.

Distributed 3D printing solves a different problem. It enables production at the point of need, makes supply chains resilient when logistics are under attack, and turns digital files into physical parts in hours. These capabilities are transformative for sustaining operations in contested environments.

But let's be clear: this is necessary, not sufficient. We can't 3D print our way to parity with China's industrial capacity. What this legislation does is build the foundation for a distributed manufacturing base that complements traditional production. The provisions lowering barriers for small manufacturers, preventing vendor lock-in, and signaling that additive manufacturing is now mission-critical infrastructure are exactly the right steps. The question is whether America will build on this foundation with the sustained investment and comprehensive industrial strategy needed to make it reality at scale.
