Tool Changer. Welcome to the new era of 3D printing!

Nine PrintTools. One extraordinary print. The H3C brings color, material versatility, and intricate detail together in a single creation. Five PrintTools blend CMYKW into full-spectrum color, one handles water-soluble PVA supports, and three add unique textures using PLA Silk and Wood. Together, they create a stunning floral design with vibrant colors, intricate details, and a beautiful sheen that brings every petal to life.

Swaptek™ – 6-second print-to-print material switch

Nine PrintTools, each with its own dedicated filament path and heater, keep every material loaded, preheated, and ready to print. No need to retract one filament before loading another. With an optimized design, fine-tuned parameters, and active preheating, switching between PrintTools takes as little as 6 seconds.

3.4s Tool Change · 0.038g Low Purge* · Multi-process

Active Pre-Heat: Preheat the next nozzle before you need it.

Heating a nozzle usually means waiting. Active Pre-Heat looks ahead to the next tool change and warms the incoming nozzle while the current one is still printing—so the new material starts laying down within 6 seconds.

FlexFeed Extruder: Soft TPU, up to 3× faster*—without jams*.

Printing soft TPU has traditionally been slow because flexible filament can buckle before reaching the nozzle, limiting extrusion speed. FlexFeed supports both 1.75 mm and 2.85 mm filament, with dedicated 2.85 mm TPU providing greater resistance to buckling and higher volumetric flow. The result? Reliable printing with TPU as soft as 75A at up to 3× the flow rate of traditional printers.

Mixed Nozzle Sizes: Speed where you want it. Detail where it matters.

The dial, case, and flexible TPU band are printed together as one piece. Fine dial details call for a 0.2 mm nozzle, the case is better suited to 0.4 mm, and the soft band requires a dedicated 0.4 mm TPU nozzle. H3C can carry different nozzle sizes at once. Paired with Bambu Studio’s new mixed-diameter toolpath planning algorithm, each nozzle prints at a layer height that suits it and plays to its strengths, without having to share a single layer height.

Retractable Rack: It’s all about curiosity

Watching a print come to life is part of the magic of 3D printing. That's why the rack retracts out of view, giving you a clear look inside the chamber. Pull up a chair, watch the first layer take shape, and enjoy the process. It's something that never gets old.

More Than 3D Printing (Optional)

Swaptek isn’t limited to PrintTools. Optional CutTool, DrawTool, DebossTool—and more—mount the same way and switch automatically. Multi-process projects no longer mean multiple machines, manual swaps, or repeated setups. One job, every process, hands off.

AMS 3H – Filament Management Built for Tool Changer

A fully enclosed, integrated filament management system built for Swaptek™: every roll stays sealed against moisture and feeds automatically into the PrintTool. A built-in 2-slot dryer takes extra care of the most hygroscopic filaments—PA, PET, and TPU.

9-Slot · 85°C Dryer* · Auto-Loading

Auto Filament Loader: No guesswork on loading.

No more manual loading. Drop a filament into any of the nine slots and the AMS 3H detects, routes, and engages it with the PrintTool automatically—across all 9 paths.

Built-In Dryer: Drying, integrated into the print flow.

A dedicated 2-slot dryer sits right in the filament slots and works with Swaptek™—drying on demand or mid-print*, so prep never stalls production. It reaches 85°C*, enough for engineering-grade PA, PC, and carbon-fiber-filled filaments.

Auxiliary AMS: Nine materials, with room for more.

Most toolchangers limit the number of materials to their available tools. The H3C goes further. Connect existing Bambu Lab AMS units through PrintTool No. 1 to support up to 24 filament spools, unlocking more colors and materials in a single print without changing your workflow. Already own an AMS? Simply connect it and expand your possibilities.

Integrated Design: Filament storage, built in. Not hanging off.

No spools hanging off the side, no dryer taking up valuable workspace. The H3C integrates filament storage and drying into a clean, compact design, maintaining a footprint comparable to a single-nozzle printer. No external racks or exposed filament paths. Just one streamlined, all-in-one printing solution.

Flagship Performance. No Compromise.

Behind the H3C's advanced multi-material capabilities is a foundation engineered for precision and performance. Cross-flow cooling delivers cleaner overhangs, a 65°C heated chamber helps minimize warping with engineering-grade materials, and an advanced motion system maintains fine detail even at high speeds. Complex prints demand more from your printer. The H3C is built to deliver.

Motion System Upgrade: Lighter head. Faster prints. Same precision.

The toolhead and X-axis assembly are 40% lighter*, reducing inertia for faster, more precise movement. With acceleration reaching 25,000 mm/s and travel speeds up to 1,400 mm/s, the H3C delivers exceptional speed while minimizing vibrations and ringing that can affect print quality.

Vision Encoder (Optional): 50 μm motion accuracy. Held for years, not weeks.

For projects where precision matters, from engineering components to production runs, the optional Vision Encoder helps maintain accuracy over time. By providing an absolute optical reference, it enables recalibration to compensate for mechanical wear and drift, restoring motion accuracy to under 50 μm across the build volume. Precision you can rely on, print after print.

Cross-Flow Cooling: Cooled at every level. Print clean, even in summer.

350°C Nozzle & Active Chamber Heating: Engineered for High Temperatures, From Nozzle to Chamber.

Engineering-grade filaments demand precise temperature control. The H3C delivers with active dual-zone chamber heating up to 65°C, helping maintain consistent temperatures and minimize warping. All nine hardened-steel nozzles reach up to 350°C, supporting demanding materials such as ABS, PC, PA-CF, PET-CF, and more.

More Time Making. Less Time Tinkering.

The H3C packs advanced technology into a surprisingly simple experience. Automation handles routine tasks, while AI helps make intelligent adjustments along the way. Whether you've been 3D printing for ten years or just ten minutes, the H3C makes it easy to focus on what matters most: bringing your ideas to life.

Full-Auto Calibration: Nine tools, calibrated automatically—every time.

With nine PrintTools working together, precision is essential. The H3C automatically handles PrintTool docking calibration, offset compensation for accurate color and material alignment, and bed leveling before every print. No manual adjustments needed.

AI Monitoring: It watches, so you don't have to.

A full array of vision systems* watches from before the first layer to the last. Up front, the H3C checks the chamber against your slicer setup and flags mismatches while they're easy to fix. Then its AI catches spaghetti, purge-bin jams, and clogs before they cascade. Check in whenever you like.

All-New HMS with MiniWiki: Find the fix, right on your screen.

The new HMS doesn't just throw an error code at you. It diagnoses the actual cause—narrowing it down, ranking the possibilities, and explaining what each one means in plain language. You see what's wrong, not what might be. Then MiniWiki walks you through the fix, right on the printer's screen. No QR codes. No phones. No flipping between the machine and a help page. Read the step. Do the step. Move on. Most issues resolved before your coffee gets cold.

Official Accessories: Made to fit your space.

A 3D printer shouldn't take over your space—it should fit into it. Bambu Lab's official accessories make the H3C feel like a natural part of your workspace.

Bambu Station L: Lift it up. Tidy it up.

Bambu Station L lifts the H3C to a comfortable working height—easier loading, maintenance, and monitoring, no stooping. Underneath, dedicated storage keeps tools, spare filament, and essentials right where you reach for them.

Bambu Lab E1 Air Purifier: Clean Air. No Compromises.

It captures what you can smell—and everything you can't. VOCs, PM2.5, 0.3μm Microplastics

The result? Cleaner air, fewer unwanted odors, and a more comfortable workspace. Keep your creativity flowing while the E1 helps keep the air cleaner.

Notes

1. For Bambu Lab filament, the initial weight can be read automatically through RFID or entered manually. For third-party filament, enter the initial weight manually.
2. The printer's voltage specifications vary by sales region. Before use, please check the label next to the power socket on the printer to ensure the supplied voltage matches the indicated voltage.
3. To quickly heat the heatbed to the required temperature, the printer will run at maximum power for about 3–5 minutes.
4. If the circuit has limited power capacity, you can enable Low Power Mode. After it is enabled, the total energy use remains unchanged, and the heatbed and chamber will heat up more slowly.

* "Machine stays in its working range" applies when the machine is operated within the recommended ambient temperature range. "Full array of vision systems" includes the BirdsEye top-view camera, which is sold separately and not included with the printer. AI monitoring functions operate independently of BirdsEye; the camera extends coverage rather than enabling the feature. BirdsEye-enhanced AI monitoring is currently planned for release in the first half of 2027 and is subject to change. MiniWiki covers the most common HMS codes.
