Bambu Lab H3C Appears in FCC Filing

Bambu Lab appears to be preparing another H-series 3D printer. A filing in the US Federal Communications Commission's equipment database identifies the unannounced machine as the Bambu Lab H3C.

Shenzhen Tuozhu Technology, Bambu Lab's legal entity, submitted the registration under FCC ID 2A6J8-PF008P. The compliance label describes the product as an H3C 3D Printer and gives its model number as PF008-P.

The FCC granted authorization on September 11, 2026. The public documents list dual-band Wi-Fi with Wi-Fi 6 support, but contain no product photos or printing specifications.

The label exhibit identifies the H3C as a 3D printer with model number PF008-P. Only part of the rear panel is shown.

Bambu Lab has not published the H3C's specifications or release date.

Product Photos Remain Confidential

Bambu Lab asked the FCC to keep the H3C's external and internal photos, user manual and test setup images confidential.

The label-location exhibit offers the only public view of the hardware. It shows a section of the rear panel with the power inlet and label position, but not enough of the enclosure to judge the H3C's size or layout.

Patent Filing Fuels Hotend-Changer Speculation

The FCC filing follows three Chinese Bambu Lab patent applications published in August. One of the documents describes a higher-capacity hotend-changing system and illustrates nine detachable hotends parked in a rack, with another fitted to the toolhead.

A Bambu Lab patent published in August illustrates nine hotends parked in a rack. The FCC filing makes no reference to this mechanism.

The timing has prompted speculation that the rack could be intended for the H3C. Bambu Lab already uses automatic hotend changes in the H2C, whose Vortek system combines six interchangeable hotends with a fixed nozzle. A larger rack would extend that approach to more materials or nozzle combinations.

The patent does not name the H3C, and the FCC filing does not mention a hotend rack, toolchanger or nozzle count. The nine-bay design is therefore not an H3C specification. Our earlier report takes a closer look at the Bambu Lab hotend-changing patent.

Formnext Is a Possible Reveal Window

An X2D Pro filing from Bambu Lab also entered the FCC database on September 11. The two registrations put a pair of new product names into the public record, though FCC approval does not indicate which machine will appear first.

Formnext runs in Frankfurt from November 17 to 20, giving Bambu Lab a major industry stage for a possible reveal. The company has not connected the H3C to the show, and no announcement date has been given.

Is the Bambu Lab H3C real?+

Yes. An FCC equipment authorization granted on September 11, 2026 identifies the H3C as a 3D printer submitted by Shenzhen Tuozhu Technology, Bambu Lab's legal entity.

What is confirmed in the H3C FCC filing?+

The filing confirms the H3C name, model PF008-P and dual-band Wi-Fi with Wi-Fi 6 support. It contains no details about the printer's design, build volume or printing system.

Will the Bambu Lab H3C have ten hotends?+

The filing does not say. A separate Bambu Lab patent shows nine parked hotends plus one on the toolhead, but neither document connects that design to the H3C.

When will the Bambu Lab H3C be released?+

No release date has been announced. Formnext takes place in Frankfurt from November 17 to 20 and could provide a venue for a reveal, but Bambu Lab has not connected the H3C to the event.
