Beehive’s $50M bet on metal additive manufacturing
Metal additive manufacturing in defense refers to the use of industrial metal 3D printers to produce certified, flight-ready components such as drone engines at scale, replacing or supplementing traditional casting and machining in time-sensitive, high-stakes military supply chains. Beehive Industries has committed over USD 50 million (approx. RM230,000,000) to expand its fleet of EOS metal 3D printers, placing what EOS calls the largest single publicly disclosed order in its history. The deal covers 30 EOS M4 ONYX systems to be installed in Knoxville, Tennessee, and Centennial, Colorado, bringing Beehive’s total EOS metal capacity to 50 machines. This is not a speculative purchase: Beehive reports that its process for uncrewed system engines is faster and about 60 percent cheaper than conventional methods. The move signals that industrial 3D printing investment is now driven by booked programs and repeat orders rather than one-off prototypes.
From contract award to 3D printed drone engines
Beehive’s industrial 3D printing push is directly tied to a USD 29.7 million (approx. RM136,620,000) contract to supply Frenzy 6 and Frenzy 8 engines to the Air Force. These jet engines are designed for swarm-class drones and other uncrewed aerial systems, where low-cost, high-volume output matters as much as performance. The contract spans vehicle integration, flight testing, and propulsion platform qualification, meaning additively manufactured hardware must meet strict aerospace standards. According to Beehive Industries, demand for Frenzy 8 engines is “unprecedented,” driven by major defense programs and the need for affordable, high-rate production of uncrewed systems. In parallel, the company is developing the Rampart turbofan platform for applications needing more than 1,000 pounds-force of thrust, showing how 3D printed drone engines are evolving into a broader family of propulsion products built around additive-friendly designs.
M4 ONYX and the maturation of defense manufacturing
The choice of the EOS M4 ONYX underlines how metal additive manufacturing is maturing into a production technology for defense manufacturing scaling. The platform’s six-laser architecture, expanded build volume, and advanced process monitoring are aimed at throughput and repeatable quality, not lab experiments. Beehive cites process stability, automation, and part quality as reasons for standardizing on this machine, alongside EOS software for real-time process monitoring, data tracking, and quality management. These features support traceability and certification, which are essential for aerospace propulsion. The American Center for Manufacturing Innovation was among the first M4 ONYX customers and validated its use for the military aerospace supply chain, while service bureau Incodema3D has also committed to additional systems. EOS’s CEO says Beehive’s investment shows additive manufacturing has become a “foundational production technology” for next-generation propulsion, not a niche tool.
Meeting volume and supply chain demands in a rearming world
Conflicts in recent years have left stockpiles depleted, and reports indicate the military will need years of work to rebuild its weapons inventory. That context is pushing procurement agencies toward technologies that can shorten lead times and support rapid design changes. Beehive’s expanded EOS fleet more than doubles its capacity, aligning production volume with long-term demand for uncrewed systems and propulsion upgrades. The Frenzy 8 engine, built for low-cost, high-volume output, is an example of how designs optimized for metal additive manufacturing can move quickly from development to serial production. Industrial 3D printing investment on this scale also shows that supply chains are willing to trust additively manufactured parts for critical functions, provided vendors can demonstrate repeatability and certification. As more contractors adopt this model, metal additive manufacturing becomes embedded in the defense industrial base rather than sitting on the margins.
