A new Bambu Lab printer, referenced as the H3C, has quietly appeared in a U.S. Federal Communications Commission (FCC) filing dated September 11, 2026. The registration, first spotted by community members on the official Bambu Lab forum, points to a machine that could represent the company’s most ambitious multi-color printing architecture to date. A second filing for an X2D Pro was also included in the same documentation, suggesting Bambu Lab is preparing multiple new products for the U.S. market.
What the FCC Filing Reveals—and What It Doesn’t
The FCC registration itself is sparse. As is typical with pre-release hardware, the filing includes photos and a user manual that remain under a confidentiality period of up to 180 days, meaning full technical details will not be publicly downloadable until that window closes. The filing does not confirm a product name, pricing, or a release date. “H3C” is currently a community designation, not an official Bambu Lab product name. The company has not announced any printer under that model number.
Patent Filings Point to a 10-Nozzle Toolchanger
The strongest evidence for the H3C’s technical direction comes not from the FCC filing but from three Chinese patent applications published on August 14, 2026. The patents—CN 122560409 A, CN 122560412 A, and CN 122560413 A—describe a multi-printhead system with a schematic showing 10 filament spools and 10 nozzles arranged in a storage rack configuration.
According to the patent drawings, nine printheads are designed to be interchangeable, parked in a rack at the rear of the machine, while a tenth printhead remains mounted on the toolhead during operation. This differs from Bambu Lab’s existing Vortek system on the H2C, which swaps only the hot end and supports a maximum of six interchangeable units. The new patents describe a system that swaps the entire printhead, a more substantial component than a hot end alone, which could allow for faster tool changes and reduced filament waste.
One patent (CN 122560409 A) also details a toolhead with illumination integrated directly into the cooling duct, using a black-and-white matte interior surface to direct light toward the nozzle without causing camera overexposure—a design intended to improve AI-based print monitoring.
Positioning Against the Toolchanger Race
The H3C, if it materializes as described, would place Bambu Lab more directly against competitors like Prusa Research (XL toolchanger, INDX) and Snapmaker (U1). Community discussion on the Bambu Lab forum suggests the company is “behind on toolchangers” and that an H3C release would be strategically important to remain competitive. However, some forum members also caution that Bambu Lab may space out its releases to avoid cannibalizing sales of the recently launched H2C and X2D series.
Timeline and Pricing Remain Unconfirmed
Bambu Lab has not issued any official statement about the H3C. Based on the standard 180-day FCC confidentiality period, community estimates place a potential reveal around March 2027, though this is speculative. Some forum users hope for a release before the 2026 holiday season, but that appears optimistic given the lack of official teasers or pricing information.
Pricing is similarly unknown. For reference, the H2C launched in November 2025, and the H2D Pro is priced at $3,799 with an AMS 2 Pro and AMS HT bundle. A 10-printhead toolchanger with a larger filament management system would likely sit at the premium end of Bambu Lab’s lineup.
X2D Pro Also Filed
The same FCC documentation that revealed the H3C also included a filing for an X2D Pro. Based on Bambu Lab’s existing naming conventions—where “Pro” variants like the H2D Pro are positioned as enterprise-grade machines with enhanced networking and security features—the X2D Pro is expected to follow a similar path, likely targeting business and educational users rather than the consumer market.
What to Watch For
Until Bambu Lab makes an official announcement, the H3C remains a patent- and filing-derived possibility rather than a confirmed product. The key signals to monitor are: the expiration of the FCC confidentiality period, any Bambu Lab teaser campaigns, and whether the company files additional trademarks or certifications in other regions. For now, the FCC registration confirms that Bambu Lab is preparing something for the U.S. market—and the patents strongly suggest it involves more nozzles than any Bambu Lab printer has offered before.
