VELO noted for metal 3D printing for engines
A SpaceX supplier called VELO was singled out on social media for metal additive‑manufacturing capability that can produce complex engine parts. (x.com) The post frames VELO’s metal printing as part of a broader trend toward using advanced manufacturing for propulsion components. (x.com)
Metal 3D printing builds metal parts layer by layer, like stacking thousands of thin welds, and rocket makers use it to make engine hardware with internal channels that are hard to machine. Velo3D was highlighted in a recent social-media post as one of the companies tied to that shift. (velo3d.com) Velo3D says its systems are used for “mission-critical” metal parts in aerospace, defense and energy, and its aerospace page says customers use the machines for propulsion, turbomachinery and high-pressure tanks. The company’s Sapphire XC 1MZ printer has a 600 millimeter diameter by 1,000 millimeter height build volume, which it markets for large aerospace components. (velo3d.com) The SpaceX link is not just social-media chatter. In a September 12, 2024 filing, Velo3D disclosed an intellectual-property license and support-services agreement with Space Exploration Technologies Corp., the formal name of SpaceX, covering Velo3D additive-manufacturing technology. (sec.gov) Velo3D’s investor page also names SpaceX among the companies that use its technology, alongside Honeywell and Lam Research. SpaceX’s supplier page says the company builds much of its hardware in-house but also uses specialized outside suppliers. (velo3d.com) (spacex.com) Rocket engines are a natural fit for this kind of manufacturing because they pack fuel, oxidizer and cooling passages into tight spaces under extreme heat and pressure. A National Aeronautics and Space Administration technical presentation on metal additive manufacturing for rocket engines describes both the promise and the failure modes, underscoring that the method is already part of mainstream propulsion development rather than a lab curiosity. (nasa.gov) Velo3D has spent years tying its printers to engine work. In 2021, it said Launcher used its systems to print Inconel and titanium parts for a liquid rocket engine program, including turbopump hardware. (velo3d.com) (engineering.com) The company kept pushing deeper into propulsion in 2025. Velo3D announced a $4 million, two-year agreement with Vaya Space in June 2025 for high-performance additive manufacturing tied to space propulsion systems, and in October 2025 it said iRocket was expanding use of Sapphire printers for reusable launch-vehicle and defense hardware. (velo3d.com 1) (velo3d.com 2) SpaceX’s own business model helps explain why suppliers that can make complex engine parts draw attention. SpaceX says Falcon 9 is reusable and says reusability lowers the cost of space access, which puts pressure on the supply chain to deliver hardware that can be produced quickly and repeatedly. (spacex.com) So the social-media post landed on a real industrial trend: rocket companies are using metal additive manufacturing not for prototypes alone, but for propulsion parts that are difficult to cast, forge or machine in one piece. Velo3D’s filings, customer list and aerospace partnerships show why its name keeps surfacing when investors talk about engine manufacturing. (sec.gov) (velo3d.com)
