AM Bottleneck Brief #7: Qualified Large-Format LPBF Capacity Is the Munitions Scaling Gate

AM Bottleneck Brief #7 · 24 October 2026

The binding constraint this week is qualified large-format laser powder bed fusion (L-PBF) capacity. On 22 October 2026, Nikon Advanced Manufacturing (Nikon AM) announced a Department of War contract for multiple L-PBF systems with a 2 m z-height, for Tomahawk mid-bodies. Nikon’s largest production system today, the NXG 600E, builds to 1,500 mm. Missile demand is under contract. Machines tall enough for these parts, qualified for flight hardware, are still being built.

What changed

• 22 Oct 2026, Nikon AM. Contract with the Department of War under the Industrial Base Analysis and Sustainment (IBAS) program, awarded through the Cornerstone Other Transaction Authority (COTA). Scope: multiple specially developed L-PBF systems with 2 m z-height, based on the NXG-E platform, for Tomahawk Land Attack Missile (TLAM) mid-bodies and similar applications. Work runs at the Nikon AM Technology Center in Long Beach, California, for prototypes and to scale production capacity. The release gives no contract value and no unit count. (Nikon AM)
• 17 Aug 2026, RTX. Raytheon received a $22.9 billion, seven-year Tomahawk contract that supports the ramp to more than 1,000 missiles a year. RTX says it delivered three times more Tomahawks in the first half of 2026 than in the first half of 2025. (RTX)
• 21 Oct 2026, 3D Systems. Opened a ~50,000 sq ft Industrial Technology Center in Littleton, Colorado, for application development, qualification and production of aerospace, defense and semiconductor-equipment parts. The site lists AS9100D, ITAR and CMMC Level 2. 3D Systems also names large-format printer manufacturing in South Carolina and a U.S. Air Force-sponsored system program in California. (3D Systems)
• 6 Oct 2026, Velo3D. Mears Machine ordered its sixth Sapphire XC. Velo3D’s CEO: “The test of production additive manufacturing is whether a customer can qualify once and then continue adding capacity and materials as demand grows.” (Velo3D)

The bottleneck

Envelope first. Nikon calls the Tomahawk systems “specially developed.” In July 2026 Nikon described the NXG 600E (600 × 600 × 1,500 mm, twelve 1 kW lasers) as the largest machine Nikon SLM Solutions makes. A 2 m z-height is a taller machine class than that. In the same release, Beehive Industries called ultra-large-format printing capacity “currently limited in the domestic market.” (Nikon SLM Solutions, 7 Jul 2026)

Qualification second. A new machine class must pass installation and equipment qualification before any part qualification counts. Methods are not yet common. ASTM’s F42 work item WK98852 states that “not all machine OEMs or machine users are using similar methods, or covering the same requirements even after 10+ years of PBF-LB/M.” It aims to refine installation/equipment qualification (IQ/EQ) and machine KPIs, building on ISO/ASTM 52945. (ASTM WK98852)

The constraint is therefore not printer count. It is qualified machine-hours in an envelope large enough for munition structures, plus the ability to add a second and third machine without restarting qualification.

Why it matters

• Demand is contracted. RTX’s $22.9 billion award and its 1,000-a-year target set the rate. AM can only take part where a qualified large machine exists.
• Large-format supply is concentrated. The named suppliers this cycle are Nikon AM (2 m NXG-E systems), 3D Systems (Air Force large-format program; Littleton qualification site) and Velo3D (Sapphire XC fleets at contract manufacturers).
• Value goes to qualify-once, copy-many capacity. This is the machine-equivalence problem from our machine equivalence analysis, now at missile scale.
• Gaps remain. Nikon gives no contract value, unit count or delivery date. No source here says AM mid-bodies are in the Tomahawk production configuration.
