Bambu Lab H3C Confirmed: Nine-Tool Tool Changer, Reveal on 3 November

What Bambu Lab has now confirmed

On 23 October, the day after the leak, Bambu Lab made it official. Here's what it has confirmed so far:

• The name and tagline: Bambu Lab H3C, "Tool Changer. Game Changer."
• The reveal: November 3, 2:00 PM GMT, given in an email from Bambu Lab UK with the subject line "Nine paths. One drop." The H3C is also now the lead banner on Bambu Lab's own homepage, which shows the same moment as 9:00 AM EST.
• Nine tools: the official teaser shows nine tool positions, each with its own filament path arching over the top of the machine from the rear.
• A drop-down rack: the 11-second teaser video shows a tool rack mounted at the front of the chamber dropping down into place.

Price, specifications and whether 3 November is an announcement or the start of orders are still to come.

What leaked

The banner was spotted by a Reddit user and shared on r/BambuLab. It appeared in the hero slot of the Australian Bambu Lab store, the same place Bambu Lab normally puts its launch teasers, and was gone when the page was reloaded. Here's what it showed:

• The name: Bambu Lab H3C, which would make it the next flagship after the H2 series.
• The tagline: "Tool Changer. Game Changer."
• The date: November 4, 1:00 AM AEDT, with a "Learn more" button.
• The image: a darkened printer with nine numbered positions along the top, each with its own filament line feeding in from above, and mechanical parts below each position.

Bambu Lab's official teaser, released the next day, matches the banner's name, tagline, nine tools and date, so the leak turned out to be accurate.

When is the reveal in UK time?

Bambu Lab UK's email confirms the reveal at 2:00pm GMT, which matches the Australian banner's 1:00am AEDT on 4 November. The UK will be back on GMT by then, so here it lands on Tuesday afternoon:

Bambu Lab hasn't said whether this is a product announcement, the start of pre-orders, or both.

Tool changer vs nozzle changer: what's different

The tagline is the most interesting part of the leak. Bambu Lab's current multi-material flagships all print through a small number of nozzles. The H2D has two. The H2C adds Bambu Lab's Vortek system, which swaps hotends from a rack, but filament changes still involve some purging. A true tool changer works differently: each position is a complete print head with its own filament loaded, and the printer parks one and picks up another instead of unloading and reloading.

Full specifications are still to come, but the practical benefits are the ones tool changers are known for:

• Far less purge waste. With filament already loaded in each head, there's little or no need to flush the old colour out.
• Faster colour and material changes. A tool swap takes seconds rather than a full unload, load and purge cycle.
• Cleaner multi-material prints. Materials that don't mix well, such as a support material and the model material, never share a nozzle.
• Per-head tuning. In principle each head can carry a different nozzle size or type for the job it's doing.

Some coverage has compared the layout to Bondtech's INDX system, developed with Prusa. The resemblance is visual only: there's no known link between Bambu Lab and either company.

The paper trail behind the leak

Neither the leak nor the confirmation came out of nowhere. Two earlier sets of documents point in the same direction.

The FCC filing

A device labelled H3C, model PF008-P, was filed with the FCC under ID 2A6J8-PF008P on 11 September 2026. The filing shows a rear power inlet and dual-band Wi-Fi. The same batch of filings also listed a P3C, an X2D Pro, and two new AMS units, the AMS 3H and AMS 3P. The external and internal photos are confidential until March 2027, which is a standard confidentiality window rather than a launch date.

The patents

Three Chinese patent applications from Bambu Lab, published on 14 August 2026 (CN 122560409 A, CN 122560412 A and CN 122560413 A), describe a printer with nine print heads parked in a rack plus one on the toolhead: ten in total. The rack uses magnetic, spring-loaded docks, and the printer lowers the bed before swapping heads near the start of a print.

Nine tools in a rack is exactly what Bambu Lab's teaser shows. Patents never name products, so we can't say for certain this is the H3C's design, but the teaser, the filing and the patents all line up neatly.

Price: what to expect

Nothing has been announced. Most coverage expects the H3C to sit above the H2C as the new top of the range, and one blogger's pre-leak guess puts it at around $2,299. With nine complete print heads instead of one or two, it would be a surprise if it came in cheaper. Wait for the official figure before planning around any number, and remember that UK prices rarely convert directly from US pricing.

What we still don't know

1. Whether 3 November is an announcement, a pre-order launch, or both.
2. The price, and whether there will be combo bundles with the new AMS units.
3. Whether the patents' tenth head, carried on the toolhead alongside the nine in the rack, is part of the final design.
4. Build volume, nozzle temperatures, chamber heating and supported materials.
5. How the AMS 3H and AMS 3P fit in, and whether existing AMS units still work.
6. Where the H2C sits in the range once the H3C arrives.
7. UK availability and shipping dates.

Should you wait before buying an H2D or H2C?

If you were about to buy a high-end multi-material Bambu Lab printer, hold off until 3 November: it's less than two weeks away, so waiting costs you very little. At worst you'll have one more option to compare. At best you'll get a far more capable machine, or a better price on the current H2 series if the range shuffles around it.

If you're shopping for a single-colour workhorse or a budget printer, this leak doesn't change much. The H3C is clearly aimed at the top end.

It's also a busy month for Bambu Lab. The S1 3D scanner is due in November too, though nothing so far links the two launches.
