Impossible Objects Raises $40M Series B Led by Inflection Equity

Impossible Objects, the Northbrook, Illinois-based developer of Composite-Based Additive Manufacturing (CBAM), has raised a $40 million Series B round. Inflection Equity led the financing, with participation from OCA Ventures, Impact Capital, Excell Partners, and Aaron Wealth Management.

What the Company Does

Impossible Objects builds industrial 3D printing technology around its CBAM process. The approach combines high-speed production with composite materials such as carbon fiber to produce strong, lightweight parts at volumes traditionally served by processes like CNC machining and injection molding.

The company positions CBAM as a manufacturing method for applications where composite strength and weight characteristics matter, and where production volume has historically pushed work toward conventional subtractive or molding processes.

Who It Serves

Impossible Objects serves customers across aerospace, defense, automotive, and other advanced-manufacturing sectors. These are markets where part performance, material properties, and production economics are closely scrutinized, and where additive approaches have often been limited to prototyping or low-volume work.

Footprint

The company operates from Northbrook, Illinois, with an additional site in Rochester, New York. That two-site footprint supports both its headquarters functions and its technical operations.

The Round at a Glance

Company: Impossible Objects
Round type: Series B
Amount: $40,000,000 USD
Lead investor: Inflection Equity
Participating investors: OCA Ventures, Impact Capital, Excell Partners, Aaron Wealth Management
Funding date: September 11, 2026
Stage: Series B

Why It Matters

The Series B marks a significant step for a company operating at the intersection of additive manufacturing and composite materials. Industrial 3D printing has drawn sustained interest from aerospace and defense buyers looking for alternatives to traditional tooling and machining workflows, particularly where lightweight composite parts are required.

For Impossible Objects, the raise provides capital at a stage when scaling production technology and serving advanced-manufacturing customers typically requires investment in systems, operations, and commercial reach. The involvement of Inflection Equity as lead, alongside a group of existing and new participants, signals continued investor appetite for industrial additive manufacturing platforms targeting high-performance composite parts.

What to Watch

With a $40 million Series B in place, the key questions for Impossible Objects center on execution: expanding deployment of its CBAM systems, deepening penetration in aerospace, defense, and automotive accounts, and demonstrating that composite-based additive manufacturing can reliably serve production volumes historically handled by CNC machining and injection molding.

The company's dual presence in Illinois and New York gives it a base from which to support that expansion as it moves through the Series B stage.
