Impossible Objects raises $40 million Series B to scale CBAM production systems

Funding round structure

Impossible Objects announced on September 14, 2026, that it has closed a $40 million Series B round to scale its Composite-Based Additive Manufacturing (CBAM) technology and meet what the company described as growing customer demand. Inflection Equity led the financing, with participation from Aaron Wealth Management, OCA Ventures, Impact Capital and Excell Partners. The company said the capital will be used to increase production of its industrial additive manufacturing systems, expand customer deployments and build out the service and commercial organization needed to support a growing installed base.

CBAM technology and machine specifications

CBAM uses high-speed production and advanced composite materials, including carbon fiber, to produce strong, lightweight parts at volume for applications traditionally served by processes such as CNC machining and injection molding while eliminating the need for expensive tooling. The CBAM 25 industrial additive manufacturing system can print up to 25 layers per minute, is 15 times faster than competing production additive technologies, and can produce composite parts with strength up to 200 MPa with minimal shrinkage and warpage. CEO Steve Hoover said the system is designed to combine high productivity and reliability with the flexibility and tool-less manufacturing that modern flexible supply chains require, adding that the funding will help the company scale to meet demand for adaptable production.

Customer deployments and defense applications

Since launching the CBAM 25 in early 2025, Impossible Objects has taken five orders and begun deploying the system across aerospace, defense and advanced manufacturing, including with the U.S. Air Force, the National Institute for Aviation Research, the Oregon Manufacturing Innovation Center and Rochester Institute of Technology. The technology is included in the U.S. Air Force Technology Roadmap. At U.S. Army Rock Island Arsenal, CBAM is supporting the production of up to 10,000 drone bodies per month, and the company has secured $20 million in U.S. government contracts and awards, with work through Small Business Innovation Research Phase I and Phase II awards supporting the development of high-strength long-range drones with integrated wiring inside additively manufactured parts.

Investor and external commentary

Gintaras Vaisnys, Managing Partner at Inflection Equity, said the firm was doubling down on Impossible Objects as it enters its next phase of commercial scale, describing the system as one that can operate at production rates and is seeing explosive demand across commercial and government applications. Stephen Farmen, a retired U.S. Army major general, said the nature of warfare is changing as new technologies are deployed, and that the defense industrial base needs new advanced manufacturing technologies that can deliver capabilities at speed and scale.

Capital deployment and scaling outlook

The company framed CBAM as a response to what it described as a longstanding limitation of 3D printing, which has largely remained a prototyping technology constrained by speed, materials and cost. With the new financing, Impossible Objects said it will expand its installed base across defense and commercial customers, with manufacturing capacity at sites such as Rock Island Arsenal positioned to support high-volume drone body output in the near term.
