Impossible Objects Lands $40M to Scale Industrial 3D Printing

Impossible Objects has closed a $40 million Series B round to scale its Composite-Based Additive Manufacturing technology beyond prototype shops into full production environments. The funding, led by Inflection Equity with participation from Aaron Wealth Management, OCA Ventures, Impact Capital and Excell Partners, signals growing investor confidence in carbon-fiber 3D printing for industrial use.

CBAM 25 Targets the Speed Problem

The core pitch is simple: most additive manufacturing still cannot compete with CNC machining or injection molding on volume. Impossible Objects says its CBAM 25 system prints up to 25 layers per minute, which the company claims is 15 times faster than competing production-grade additive technologies. The system uses carbon-fiber reinforced composite materials and produces parts with strength up to 200 MPa, which the company says is four times stronger than typical additive parts.

These claims have not been independently verified by third parties. They reflect Impossible Objects' own characterization of the system.

Already Deployed at Scale

The CBAM 25 launched in early 2025. Since then, Impossible Objects has taken five orders and placed systems at the U.S. Air Force, the National Institute for Aviation Research, the Oregon Manufacturing Innovation Center and Rochester Institute of Technology. At the U.S. Army's Rock Island Arsenal, the system is positioned to support production of up to 10,000 drone bodies per month.

The company also holds $20 million in U.S. government Small Business Innovation Research awards. Those contracts fund work on high-strength long-range drones, composites with strength comparable to conventionally manufactured materials, integrated wiring embedded inside printed parts, and lightweight aircraft wing and fuselage structures. The Air Force has included the technology in its official technology roadmap.

Where the Money Goes

Impossible Objects plans to use the Series B proceeds to increase production of its CBAM 25 systems, expand customer deployments, and build out its service and commercial organization. CEO Steve Hoover said the system was designed from the ground up to meet the high productivity and reliability needs of advanced manufacturing while preserving the tool-less flexibility that modern supply chains require.

Inflection Equity managing partner Gintaras Vaisnys framed the investment around demand he described as explosive across both commercial and government customers. The firm led the round and is now doubling down as the company moves from early adoption to commercial scale.

Competitive Context

Other companies are chasing the same gap between prototyping and production. Hadrian launched Hadrian Additive specifically to convert 3D printing from prototype to production for U.S. defense programs and closed a $260 million Series C in mid-2025. That total funding is nearly $500 million to date, dwarfing Impossible Objects' raise.

Impossible Objects is betting that its carbon-fiber composites and layer-per-minute speed will win over manufacturers that need certified, high-throughput production without expensive tooling. The next 12 to 18 months should show whether the CBAM 25 can move from promising deployments to sustained industrial adoption.
