Impossible Objects Raises $40M to Scale Composite 3D Printing for Production

Impossible Objects has closed a $40 million Series B funding round to scale its Composite-Based Additive Manufacturing (CBAM) technology and meet what it describes as growing demand from commercial and government customers.

Inflection Equity led the round, with participation from Aaron Wealth Management, OCA Ventures, Impact Capital and Excell Partners. The money goes toward increasing production of the company's CBAM 25 system, expanding customer deployments and building out the service and commercial teams needed for a larger installed base.

What CBAM Does Differently

CBAM uses carbon-fibre reinforced materials to produce strong, lightweight parts at volumes traditionally handled by CNC machining and injection moulding. The CBAM 25, launched in early 2025, prints up to 25 layers per minute and is rated for composite parts with strength up to 200 MPa and minimal shrinkage or warpage.

That throughput puts it in a different class from most desktop or even industrial 3D printers. The machine is designed for factories, not workshops.

Defence and Government Footprint

Impossible Objects has already secured five CBAM 25 orders and deployed the system at the U.S. Air Force, the National Institute for Aviation Research, the Oregon Manufacturing Innovation Center and Rochester Institute of Technology. The company holds $20 million in U.S. government contracts and SBIR awards, including Phase I and Phase II work on high-strength long-range drones with integrated wiring inside additively manufactured parts.

At the U.S. Army Rock Island Arsenal, CBAM is being used to produce up to 10,000 drone bodies per month. That is a genuinely industrial cadence for a 3D-printed part.

What the Funding Means

The Series B gives Impossible Objects the capital to move from pilot deployments to wider rollout. CEO Steve Hoover said the company is seeing demand for manufacturing that can adapt faster without sacrificing production-grade performance. Inflection Equity's Gintaras Vaisnys described the demand as explosive across commercial and government applications.

Retired U.S. Army major general Stephen Farmen put it plainly: the defence industrial base needs advanced manufacturing technologies that deliver distributed production, faster repair parts and radically shorter delivery timelines. CBAM is positioned as one answer to that problem.

The CBAM 25 competes with traditional composite layup and metal machining in aerospace, defence and automotive. Whether it displaces those processes at scale depends on how quickly Impossible Objects can ship machines and train operators. This funding round is the clearest signal yet that the market is willing to bet on the outcome.
