Bambu Lab H3C: Reported Toolchanger Teaser Shows November Date

Supplied H3C teaser image, reportedly posted to a Bambu Lab Telegram channel on October 22 and removed shortly afterward. The original post has not been independently verified.

A Bambu Lab H3C teaser image supplied to 3DPCC News shows a rack with nine numbered positions and points to a November reveal, following the printer's appearance in FCC records.

The image carries the line “Tool Changer. Game Changer.” and gives November 4 at 1:00 AM AEDT. That is November 3 at 14:00 UTC, or 15:00 CET. The person who supplied the image says it appeared in a Bambu Lab Telegram channel on the morning of October 22 and was deleted shortly afterward. The supplied screenshot does not identify the channel.

The numbered positions make the earlier hotend-rack patent more relevant to the H3C story, but the image does not explain the mechanism. It does not establish whether complete toolheads or only hotends are exchanged, nor confirm a filament capacity, price or shipping date. The date shown is a teaser for a reveal, not evidence that orders or deliveries will begin then.

H3C Registered With the FCC

The H3C name already appears in the US Federal Communications Commission's equipment database.

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, but contain no full product photos or printing specifications.

The public FCC label identifies the machine as an H3C 3D Printer, model PF008-P.

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

Filing detail	Public record
Product name	H3C
Product type	3D Printer
Model	PF008-P
FCC ID	2A6J8-PF008P
Applicant	Shenzhen Tuozhu Technology Co., Ltd.
Grant date	September 11, 2026
Wireless	Dual-band Wi-Fi

The FCC filing does not specify the H3C's printing system, price or launch 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.

Within the FCC record, 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

A separate Chinese Bambu Lab patent application published in August describes a hotend-changing system and illustrates a rack with nine positions.

A Bambu Lab patent published in August illustrates a rack with nine positions. Neither the filing nor the supplied teaser explicitly connects the H3C to this patent.

The patent describes changing the hotend while keeping the extruder on the toolhead. That differs from printers such as the Prusa XL, which exchange complete toolheads with their own extruders. More parked hotends would not, by itself, establish how many filaments the H3C could use or which combinations it would support.

The patent does not name the H3C, and the FCC filing does not mention a hotend rack, toolchanger or nozzle count. A visual resemblance to the supplied image does not establish that the patent describes the production machine. Our earlier report takes a closer look at the Bambu Lab hotend-changing patent.

S1 and New AMS Filings Follow

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.

Further filings have since named an S1 3D scanner, AMS 3H and AMS 3P. We covered their public labels and drawings in our S1 and AMS filing report. They add to the list of possible Bambu Lab releases, but do not establish a connection between the H3C and the new material systems. Compatibility will need to come from the product specifications, not the model names.

Has Bambu Lab announced the H3C?+

The H3C name is confirmed in a public FCC filing. A teaser image supplied on October 22 names the H3C and shows a reveal date, but its reported posting to and removal from a Bambu Lab Telegram channel have not been independently verified.

What is confirmed in the H3C FCC filing?+

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

Does the H3C teaser confirm nine toolheads?+

No. Nine numbered positions are visible in the supplied image, but it does not explain whether the machine exchanges complete toolheads or only hotends. Neither the image nor the FCC filing establishes the supported filament capacity.

When will the Bambu Lab H3C be released?+

The supplied teaser image displays November 4 at 1:00 AM AEDT, equivalent to November 3 at 14:00 UTC or 15:00 CET. Its original posting has not been independently verified, and the displayed time does not confirm when orders or shipping will begin.
