Bambu Lab Sets November 3 Launch for H3C, a Nine-Tool Changer Printer

Bambu Lab has announced that its long-awaited tool-changing 3D printer, the H3C, will go on sale on November 3. A teaser released by the company shows a machine with nine tools stored on a Vortex-style rack at the front of the chamber.

Tool changers are widely seen as the direction the industry is heading, because they can swap colors faster and produce less waste than Bambu Lab's existing AMS system. Most specifications for the H3C remain under wraps, though some details have emerged.

The H3C belongs to Bambu Lab's flagship H-line, which already includes the H2S, H2D and H2C. It is most closely related to the H2C, a seven-tool, induction-heated "nozzle swapper" that uses a motorized Vortex rack to hold tools that are not in use. The H2C is among the company's larger machines, with a build volume of 330 x 320 x 325mm.

The teaser runs 11 seconds and shows the tool rack dropping down, accompanied by a metallic snick. Because idle tool heads are stored above the build plate, they should not obstruct the view of the first layer being printed. Tom's Hardware's writer noted that this has been a drawback of the Bondtech INDX system, which was reviewed on a Prusa CORE One and requires users to look through the tool rack to see inside the printer. Visibility on the H3C is likely to be better, the writer said.

Speculation has been widespread online, with several YouTubers who do not have review units analyzing leaked clues. One "AI-enhanced" image appeared to show 10 spools, which the teaser now shows to be incorrect. The video clearly shows nine colorful Bowden tools arching over the top of the printer. Tom's Hardware said it could not disclose what holds the spools, but described the system as a very Bambu sort of design.

The H2 line has been promoted as a home manufacturing hub, and the writer suggested the H3C may follow that approach. At Formnext last year, shortly after the H2C appeared, the writer spoke with Dr. Tao of Bambu Lab, who was keen on building multitasking machines that do more than 3D print.

Not everyone welcomed the addition of a laser to the H2D. Even so, the Bambu Lab A2L offers an optional blade cutting and embossing tool, which suggests the multitasking idea remains part of the company's plans.

Tom's Hardware said the H3C has a few surprises that have yet to be revealed. Full details are expected when the printer launches on November 3.
