Bambu Lab confirms H3C nine-tool printer for November 3

Consumers who pre-order or wait for the new Bambu Lab H3C will receive a machine on November 3. The company confirmed the date for its upcoming tool-changing 3D printer, ending a period of speculation about its release. The H3C joins the company’s existing H-line lineup, which includes the H2S, H2D, and H2C models.

The H3C is designed to swap between nine different tools. A teaser video released by Bambu Lab shows these tools stored on a rack positioned at the front of the chamber. This design allows the idle tool heads to sit above the build plate. Consequently, users will have a clearer view of the first layer during printing. This addresses a common complaint about other tool-changer systems, such as the Bondtech INDX used on the Prusa CORE One, where the rack can obstruct the user's line of sight.

The new printer is most closely related to the H2C. That model features seven tools and uses induction heating for nozzle swapping. The H2C has a build volume of 330 x 320 x 325mm. While specific dimensions for the H3C have not been disclosed, it is expected to fit within the same size class. Tool changers are considered the next standard in the industry because they change colors faster and generate less filament waste than the Automatic Material System, or AMS, used in previous Bambu Lab printers.

Online speculation about the H3C has focused on its material handling. Some leaked images suggested a ten-spool capacity, but the official teaser contradicts this. The video clearly shows nine colorful Bowden tools arching over the top of the printer. Bambu Lab has not yet detailed how the spools are held, though the company described the system as a distinctive design choice.

The H3C may also follow the H2 line’s focus on multitasking. At the Formnext trade show last year, Dr. Tao of Bambu Lab discussed the company’s goal of building machines that perform functions beyond standard 3D printing. The H2D includes a laser, and the A2L offers optional blade cutting and embossing tools. These features suggest the H3C may incorporate similar capabilities, although Bambu Lab has not confirmed the specific tools included in the nine-tool rack.

Most technical specifications for the H3C remain confidential. The company indicated that full details will be available at launch. The 11-second teaser video highlights the mechanical movement of the tool rack dropping into position. This action is accompanied by a distinct metallic sound, emphasizing the physical interaction of the tool heads.
