Impossible Objects Raises $40M to Scale Its Industrial 3D Printing Tech

Impossible Objects closed a $40 million Series B round to scale its Composite-Based Additive Manufacturing platform, a process it says can print strong, lightweight composite parts at volumes that rival traditional tooling.

The CBAM 25 system, launched in early 2025, deposits layers in under four seconds each and runs at up to 25 layers per minute. Impossible Objects claims that makes it 15 times faster than competing production additive technologies. Parts reach strengths up to 200 MPa, roughly four times stronger than comparable additive processes, with minimal warpage.

Inflection Equity led the round, with participation from Aaron Wealth Management, OCA Ventures, Impact Capital, and Excell Partners. The company plans to raise an additional $30 million to $50 million within the next 12 to 18 months.

Customer deployments are already underway. The U.S. Air Force, the National Institute for Aviation Research, the Oregon Manufacturing Innovation Center, and Rochester Institute of Technology are all using the system. At the U.S. Army Rock Island Arsenal, CBAM 25 is capable of producing up to 10,000 drone bodies per month.

The technology combines long-fiber carbon or fiberglass fabrics with high-performance polymer powders, including PEEK. The result is a part that competes with CNC-machined or injection-molded components but without the upfront tooling cost or lead time. Impossible Objects is pitching it at aerospace, defense, electronics, and automotive buyers who need low-volume or rapidly changing production.

The funding will go toward increasing system production, expanding customer deployments, and building out service and commercial teams to support a growing installed base.
