Velo3D, Inc. (VELO)

“The real opportunity in 3D printing is not the machine — it’s the elimination of post-processing.”

This principle animates Velo3D: the company manufactures industrial metal 3D printers, most prominently the Sapphire line, intended to print complex metal parts for aerospace, defence, and automotive customers. But what sets Velo3D apart from the crowded field of additive-manufacturing equipment makers is its focus on parts that are geometrically difficult to create any other way, and on machines that can print them cleanly enough to skip the costly machining and finishing work that traditionally follows 3D printing.

Velo3D’s Sapphire printers use a laser to fuse fine metal powder into precise shapes, layer by layer. The company claims that its proprietary beam-shaping and powder-management systems allow parts to be printed with surface finishes and dimensional accuracy close to finished, meaning customers can take a part from the machine and use it with minimal or no additional finishing. In traditional manufacturing, a part might be cast or forged, then machined, ground, and polished to meet specifications. With a Velo3D system, the theory goes, you print the final shape and send it straight to assembly. The economic advantage is not in reducing the time or cost of the printer itself, but in collapsing the cost and timeline of everything that comes after.

The industrial 3D printing market is dominated by established players like 3D Systems and EOS, both of which have been selling metal-printing equipment for years. Velo3D is younger and smaller, founded in 2014 by Benny Buller and Ric Fulop (the latter a serial entrepreneur in the space). The company went public in 2021 via a SPAC merger, which accelerated its growth ambitions but also brought investor expectations and earnings pressure. The core customer base is aerospace and defence: companies that design and build engines, landing gear, fuel systems, and complex avionics mounts — the kinds of components where weight is expensive, lead time is critical, and making one-off custom parts by hand or tooling up conventional production is not economical.

The business model is straightforward: Velo3D manufactures and sells the machines, then earns recurring revenue from software subscriptions, maintenance contracts, and supplies (the proprietary metal powders used as feedstock for printing). A single Sapphire machine carries a price in the range of two million dollars or more, which means each sale is a significant event for the company’s quarterly revenue. Because the installed base of machines is relatively small — perhaps in the hundreds across all customers — the business is lumpy: a few major customer wins or delays can move the quarterly results significantly.

The value proposition depends entirely on whether the premise holds: can parts really be printed reliably enough to skip post-processing? This is where Velo3D’s engineering stands under constant scrutiny. If a customer receives parts that require significant finishing anyway, the economics collapse and the machine becomes another expensive industrial asset that doesn’t pay for itself. Demonstrating repeatability and quality consistency is therefore not just a marketing challenge but a fundamental engineering one. The company publishes case studies and has been transparent with early adopters, but there is inherent risk that the technology does not scale as smoothly as the engineering claims suggest.

Velo3D’s competitive position is also narrower than some incumbents. The company is not, at this point, a full-service additive-manufacturing ecosystem the way 3D Systems or EOS are — it focuses on the machine and software for metal printing rather than comprehensive design, simulation, and production-management tools. This focus is partly a matter of resources and partly strategic: by excelling at the core print quality problem, Velo3D lets customers integrate the system into their own existing production workflows. But it also means the company is always vulnerable to larger competitors who could add a superior metal-printing capability to their existing platforms.

The aerospace and defence market is deeply cyclical and politically sensitive. Commercial aircraft orders rise and fall on fuel prices, airline economics, and travel demand; defence spending is a budget-appropriation question. In downturns, expensive capital equipment like 3D printers are among the first purchases to be deferred. Furthermore, aerospace customers are notoriously slow to qualify new suppliers and technology — getting a Velo3D system approved for production use in a jet engine or landing gear assembly can take years, even after the technical capability is proven. This lengthy sales cycle means that near-term revenue is highly dependent on deals that are often already in the pipeline; sudden demand shocks do not translate to quarterly results as quickly as they would in many other businesses.

The supply-side risk is also material. Metal powders for 3D printing are specialized materials, not commodity supplies, and Velo3D depends on reliable powder suppliers as well as the availability of raw materials like titanium, nickel-based superalloys, and aluminum alloys. Any major disruption to powder supply — whether from a supplier failure, geopolitical tension affecting raw materials, or manufacturing mishap — could halt customer production and damage the reputation of the installed base.

The long-term opportunity is genuinely large: the aerospace and defence industries manufacture enormous quantities of expensive metal parts where the tooling costs, weight savings, and lead-time benefits of 3D printing could be transformative. But near-term success depends on Velo3D proving that its engineering delivers on the promise, scaling the install base from hundreds to thousands of machines, and maintaining enough financial discipline to weather the inevitable swings in customer demand. The company’s earnings history has been volatile, with losses in some periods as it invested in manufacturing capacity and product development, and this volatility is likely to continue until the business reaches meaningful scale.

For an investor or analyst studying Velo3D, the annual 10-K filing (SEC CIK 0001825079) details the backlog of orders, the customer concentration (what percentage of revenue comes from the top five customers), and the gross margins on machine sales and recurring revenue. Watch the quarterly customer win announcements: Velo3D announces major new customer engagements, and tracking whether these translate to actual orders and shipments within reasonable timelines reveals whether sales cycles are accelerating or extending. And pay attention to commentary on gross margins and service revenue growth — these reveal whether the printing quality is holding up and whether customers are satisfied enough to purchase support contracts and materials.
