Multi-material 3D printing has traditionally meant purge towers, manual filament swaps, and constant machine babysitting. Bambu Lab’s new H2C is built to eliminate all of that. It introduces a set of engineering upgrades that make advanced printing fast, automated, and waste-free. Here are the four features that make the biggest difference.
Multi-Material Printing Without Purge Waste
The H2C’s Vortek Hotend Change System supports six dedicated hotends—one per material—removing the need for purge towers entirely. Paired with AMS, it scales to 24 filaments. The result: zero purge waste and significantly shorter print times.

A Toolhead That Manages Itself
Each hotend stores its last-used filament, allowing the printer to auto-assign the correct one for new jobs. Combined with touchless calibration, automated nozzle cleaning, automatic filament assignment, and real-time extrusion monitoring via a macro lens camera, the H2C operates with minimal user oversight.
Contactless Communication for Industrial-Grade Reliability
Instead of relying on mechanical connectors, the H2C uses a high-frequency, contactless communication system between the printhead and hotends. This ensures consistent temperature control and micrometer-level tool-change accuracy across long prints.

From Room Temperature to 350°C in 8 Seconds
An inductive heating system brings each hotend to operating temperature in just 8 seconds, accelerating prep time and material changes while also extending component lifespan.
A New Standard for Ease of Use
By removing purge waste, automating setup, improving tool-change reliability, and drastically speeding up heating, the H2C delivers a streamlined, production-ready 3D printing experience. It’s built for creators who want multi-material capabilities without the usual complexity.
