If you’ve already unboxed and leveled your H2D, the next step is getting it talking to Bambu Studio on your computer. This guide covers installing the slicer, adding the printer over the cloud or through LAN Only Mode, picking the right printer, nozzle, and plate profile for a dual-nozzle machine, assigning filament to each hotend, and finding Bambu’s official material profiles for this printer.
This is a setup guide, not a troubleshooting one. If your printer is already connected and throwing HMS error codes, check the H2D HMS error index instead.
Downloading and Installing Bambu Studio
Bambu Studio is free and available for Windows, macOS, and Linux from the Software section of bambulab.com, with Linux and older builds also mirrored on the official BambuStudio GitHub repository. The H2D needs Bambu Studio version 2.0.0.95 or later; some newer H2D features, like remote AMS drying control from Studio’s Devices page, need both a newer Studio release and a matching firmware version, so keep both updated rather than just one.
- Windows: choose the installer (.exe) or the portable (.zip) build. Windows 10 or later is required.
- macOS: download the .dmg, then drag the app into Applications. macOS 10.15 or later is required.
- Linux: the AppImage needs its executable bit set before it will launch.
On first launch, Studio asks you to pick a printer model to load its default profiles. Signing in with a Bambu Lab account at this point syncs filament and process profiles across devices, but it isn’t required to slice or print offline.
Adding the H2D: Cloud Account vs. LAN Only Mode
Bambu Studio talks to the printer one of two ways, and the choice affects more than how you click print.
Cloud mode binds the printer to your Bambu account: connect the H2D to Wi-Fi, bind it through the touchscreen or the Bambu Handy app, then sign into the same account in Studio and confirm the pairing under the Device tab. This gets you remote monitoring, the live camera feed, and control from Bambu Handy anywhere with internet, at the cost of routing status data and print jobs through Bambu’s servers even when your computer sits next to the printer.
LAN Only Mode keeps everything local: turn it on from the printer’s Settings, then add the printer in Studio using the access code shown on that same screen (plus the printer’s IP address if your network doesn’t support local discovery broadcasts). Nothing about the print or your files leaves your network this way, but Bambu Handy loses remote access to that printer, and a manually added LAN printer doesn’t keep its IP address saved between Studio sessions on a segmented network.
Both modes slice and print at identical quality. The difference is entirely about what leaves your network and what you can do while away from the machine. You can switch between them later from the printer’s settings screen.
Selecting the Printer, Nozzle, and Build Plate Profile
Once the printer is added, Studio needs to know the exact hardware configuration you’re slicing for, which is more involved on a dual-nozzle machine than on a single-nozzle Bambu printer.
- Printer profile: search for “Bambu Lab H2D” in the printer dropdown on the Prepare tab.
- Nozzle diameter: Studio’s nozzle diameter setting applies to both hotends together, with 0.2, 0.4, 0.6, and 0.8mm options and 0.4mm as the default that covers most prints. As of this writing, running two different nozzle diameters at once, one fine nozzle for walls and a larger one for infill, isn’t supported; it’s a frequently requested feature on Bambu’s public GitHub tracker, not a limitation this guide can work around.
- Nozzle material: the H2D supports standard, hardened steel, and tungsten carbide nozzle options depending on what’s installed, with tungsten carbide requiring firmware 01.02.30.00 or later. Match this to what’s actually screwed into each hotend, since printing abrasive filament through the wrong nozzle preset shortens its life.
- Build plate: pick the plate installed from the sidebar dropdown, Cool Plate, Engineering Plate, High Temp Plate, or Textured PEI Plate. This changes the bed temperature and adhesion settings Studio applies, so the wrong choice can cause a print to fail to stick or overheat filament that shouldn’t run that hot.
Assigning Filament to the Left and Right Nozzle
This is the step with no equivalent on a single-nozzle Bambu printer. Studio treats the two hotends as separate filament slots in a project, and it decides which nozzle prints which filament based on the model.
For a single-material print, only one hotend is used and there’s nothing to assign. For a two-color or two-material model, Studio’s default behavior (Filament-Saving Mode) puts one filament on each nozzle so switching between them during the print is a toolhead move rather than a purge. Add a third filament and at least one nozzle has to switch internally, which does purge some material, though Studio still groups repeat filaments onto separate nozzles first to hold that down. If you want to set the assignment yourself instead of taking Studio’s default, use Rearrange Filament, switch to Customize, and click a filament or its exchange icon to move it to the other extruder.
Two materials are locked to one side regardless of what you choose: TPU with a hardness of 90A or higher can run on the left extruder as of Bambu Studio 2.5.0, but the right extruder is still the only option for softer TPU (85A) and remains the recommended path for most TPU printing; carbon-fiber-filled filament is restricted to the left extruder only. Studio won’t let you place either one where it doesn’t belong, and our filament loading guide covers the physical loading side of this in more detail.
Setting Up AMS in Bambu Studio
If an AMS 2 Pro or AMS HT is connected, Studio detects it as soon as the printer connection is active, in either cloud or LAN mode. Official Bambu spools get read automatically through RFID; third-party filament needs the material type and color tagged manually on each slot, or Studio shows it as unassigned until you do.
Studio also shows a mapping screen when you send a job, matching each filament in your project to a physical AMS slot, weighted first by material type and then by closest color. On a dual-nozzle setup with several connected units this mapping can get less obvious than on a single-nozzle printer, so it’s worth checking the mapping screen rather than assuming Studio picked the slot you expected, especially the first few times you print with more than one AMS unit attached.
If your AMS units support it and your firmware is current, remote drying can now be started directly from Studio’s Devices page rather than only from the touchscreen: click the humidity icon on the AMS you want and start or stop the cycle from there. Drying temperature drops automatically if you start this while a print is already running.
Finding Official Material Profiles for the H2D
Bambu’s own filament profiles for the H2D, including engineering-tier materials like PA, PA-CF, and PC meant for AMS HT, are built into Studio’s filament library and appear once you’ve selected the H2D printer and matching nozzle preset. You don’t need to download these separately for Bambu-branded filament.
For checking which filaments are validated for a given nozzle, plate, and AMS combination, Bambu maintains a compatibility reference table on wiki.bambulab.com titled “Filament guide – Printer, Nozzle, AMS, Build Plate, Glue Compatibility and Required Parameters.” It’s worth checking before buying anything that needs a hardened or tungsten carbide nozzle. Staying signed into your Bambu account in Studio pulls in new or updated profiles automatically as Bambu adds them.
For anything outside Bambu’s own lineup, you’ll be creating or importing a custom filament profile rather than relying on an official one, which is a separate topic from this setup guide.
