Bambu Lab is officially launching the H2C at Formnext

Bambu Lab will officially launch its latest 3D printer, the H2C, on November 18, 2025, at 3:00 PM CET during the Formnext trade show in Frankfurt. The H2C introduces a wireless hotend swapping system designed to eliminate filament waste in multi-material printing, marking a significant evolution in the company’s product line.

At the core of the H2C is a technology the company calls “Vortek,” a system that allows the printer to automatically swap hotends without requiring purge towers or manual intervention. Traditional 3D printers must eject melted filament to clear the nozzle when changing materials or colors, resulting in waste and extended print times. The Vortek system replaces this purge process by switching the entire hotend instead of cleaning it, much like changing a paintbrush rather than rinsing it.

The innovation is based on a compact hotend design that weighs just 10 grams and measures 20 × 15 × 56 millimeters. Rather than using mechanical connectors, the H2C utilizes induction heating to bring the nozzle to operating temperature rapidly—reportedly in under eight seconds—and wirelessly transmits data, such as temperature and material type, using an embedded microcircuit and a custom PCB. Bambu Lab states that this configuration enables consistent, reliable operation with up to seven hotends per printer: one fixed and six swappable.

The H2C’s hardware is supported by tightly integrated software updates, including firmware changes and slicer support designed to manage the new system. Bambu Lab has emphasized the importance of precision in both hardware alignment and software calibration, noting that even micrometer-scale misalignments can cause visible defects on prints. According to the company, achieving this level of repeatability across every unit required significant investment in mechanical engineering and quality control.

Shipping is expected to begin by the end of 2025. For users of the company’s existing H2D and H2S models, Bambu Lab has confirmed that an upgrade path to the H2C is technically possible. However, the process is not trivial. The company notes that retrofitting the new system involves careful mechanical work and firmware configuration, recommending the upgrade only for advanced users with time and technical proficiency.

The H2C is not a direct replacement for the H2D, which remains in production. Instead, the company positions the H2C as a premium option for users who prioritize fast, clean, multi-material printing. It is particularly aimed at creators and professionals managing complex print jobs where color accuracy, material variety, and reduced waste are key.

Pricing for the H2C has not been announced. Observers expect the system to carry a premium over the H2D, due to the added hardware complexity and wireless technology. The H2C will be on display at Bambu Lab’s Formnext booth, with live demonstrations anticipated during the launch event.
