Beehive invests $50M in 30 EOS M 400-4 ONYX metal AM machines
Beehive Industries, based in Denver, Colorado, USA, has announced a $50 million order for thirty EOS M 400-4 ONYX Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machines. The machines are expected to be delivered over the next twelve months to its facilities in Knoxville, Tennessee, and Centennial, Colorado. The investment will increase Beehive’s installed base to fifty EOS metal AM machines and support production of its flagship Frenzy 8 engine line.
“Beehive is experiencing unprecedented demand for our Frenzy 8 engines driven by major defense programs and the urgent need for affordable, high-rate production of uncrewed systems,” said Darius Ehteshami, COO and CFO of Beehive Industries. “Our expanded collaboration with EOS and this substantial investment in best-in-class 3D printers will significantly increase our production capacity while reinforcing our commitment to delivering scalable, American-made propulsion solutions that strengthen warfighter capabilities.”
Beehive Industries’ investments follow a series of major milestones, including successful high-altitude testing of the Frenzy 8 engine, flight readiness validation, and a recent $29.7 million US Air Force contract supporting vehicle integration, flight testing, and qualification of the propulsion platform. Beehive’s engines are specifically designed for swarm-class drones and other next-generation uncrewed aerial systems, enabling low-cost, high-volume production critical to evolving defence strategies.
“Choosing to expand our fleet with these 30 EOS M4 ONYX systems was a strategic decision driven by EOS’s willingness to truly partner with us. Throughout this process, the EOS team leaned in, worked creatively, and demonstrated a deep commitment to our long-term growth,” stated Jonaaron Jones, Beehive’s President of Additive Parts Sales. “We value this kind of collaborative, forward-thinking partnership, and it sets a high bar for our equipment suppliers as we continue to scale and meet our production goals.”
The EOS M4 ONYX features a six-laser architecture, an expanded build volume, and advanced process monitoring capabilities. The platform also includes EOS’ latest RFS Pro advanced powder filtration system, and is engineered specifically for demanding industries, including aerospace, defence, energy, and aviation manufacturing. Beehive will also leverage EOS’ software to support real-time process monitoring, production data tracking, and quality management, helping improve repeatability and traceability across AM operations.
“Beehive Industries’ unprecedented investment demonstrates how additive manufacturing has become a foundational production technology for the next generation of advanced propulsion systems,” added Marie Niehaus-Langer, CEO of EOS. “The success of the Frenzy engine program highlights what is possible when innovative design and industrialised Additive Manufacturing come together. We are proud to support Beehive as they expand production capacity and accelerate the delivery of high-performance technologies to customers around the world.”
