We've known since last year that Bambu Lab was going to launch a larger 3D printer, and now the wait is finally over.
It features dual extrusion, full enclosure, and a variety of functions beyond 3D printing.
The printer will be available soon, with the H2D available for pre-order at $1,899.
The H2D Combo, which includes the new AMS 2 Pro, will be sold bundled for $2,199.
The H2D Laser version will be available for pre-order at $2,799 or $3,499, depending on the laser power you choose.
This includes all the new features designed by Bambu Labs for this machine.
This is a very good printer with a rich set of features, as you can see from the official introductory video.
Specifically, the H2D is ideal for professionals looking to upgrade their equipment or makers who need to undertake various complex projects.

What is the Bambu Lab H2D?
The H2D 3D printer itself packs a lot of technology into its 492 x 514 x 625 mm footprint.
Bambu Lab has created a new type of servo motor for the extruder in the H2D.
It's called Dynasense, and unlike stepper motors, which move in fixed increments and cannot re-transmit their position or missing positions after missing a step depending on the system they are implemented in.
Bambu Lab's new motor can do just that, and it gives the printer better control over filament flow.
Regarding this motor, the company states that combined with Bambu Lab's typical algorithmic intelligence, it enables finer print extrusion quality.
Sensors and cameras are located throughout the printer, from a dedicated nozzle camera for monitoring print inconsistencies and errors to an eddy current sensor for monitoring hotend alignment during switching; there are many unseen events happening to keep the H2D running smoothly.
Dual extrusion is a key feature, with the H2D having two parallel hotends on one print head.
These hardened, high-flow hotends can heat up to 350°C and can be supplied with filament from separate spools or through independent AMS units.
This allows you to print multiple colors or materials simultaneously.
The H2D's active chamber heating allows for better environmental control to maintain consistency with warp-prone materials.
The H2D can activate multiple openings on the printer to let in cold air and exhaust filtered air.
This allows you to print PLA with the door closed.
Only 300-325 mm of the 350 mm print bed width is usable for printing, which is often a drawback of dual-extrusion 3D printers.
Overall, you can use a build volume of 300-325 x 325 x 320 mm, equipped with a fast-heating (up to 120°C) print bed and a double-sided textured PEI sheet.
Bambu Lab sets the H2D's print speed at 1,000 mm/s and acceleration at 20,000 mm/s.
Technically, its top speed is twice that of the previous X1E, but it's unlikely to be used at this maximum speed in practice.
To improve 3D printing accuracy, Bambu Lab also offers an encoder board (sold separately).
This print-like board is covered with tiny machine-readable codes that the printer's camera can detect.
This, combined with advanced calibration procedures, improves the H2D's movement accuracy to less than 0.05 mm deviation across the entire print area, with 95% confidence.
What else can it do?
In addition to being a dual-extrusion 3D printer, it also has a 2D cutting mode.
There's a blade attachment that can cut vinyl, paper, card, and similar thin sheet materials.
There are also two laser modules (10W and 40W) that can cut thicker materials to varying degrees.
Bambu Lab highlights the safety of the H2D Laser version, which includes numerous flame sensors, AI-based fire detection capabilities, hazardous shading windows, and essential additions like an emergency stop button and a portable safety key.
The H2D's new non-3D printing features are handled by new software called Bambu Suite, which uses vector and bitmap file formats for contour cutting, engraving, and similar functions.
Like 3D printable files, 2D files (and projects combining both) will be integrated into MakerWorld and become native components of the repository.
The laser version of the H2D is expected to start shipping in April.
New AMS Options
Launched today with the H2D is the AMS 2 Pro, a redesigned (yet familiar-looking) AMS unit that integrates the much-requested filament drying feature.
Bambu Lab claims it does much more, equipped with an intelligent ventilation system that exhausts humid air and seals the unit to maintain filament condition.
The AMS 2 Pro can heat up to 65 ºC to dry filament and is controlled via the printer or software on a phone or computer.
Bambu Lab also now offers the single-axis AMS HT.
The AMS HT is sold separately and is compatible with the same materials as the AMS 2 Pro, but can heat up to 85 ºC and rotate the spool while drying.
Unlike the AMS 2 Pro, which only communicates humidity information through the printer and software, the AMS HT is equipped with a display, allowing you to read the current humidity and drying status at a glance.
Additionally, Bambu Lab notes that the AMS 2 Pro filament feeding function already exists and is available on X-series and P-series machines, meaning partial backward compatibility.
Full drying functionality will be implemented after a yet-to-be-determined firmware update.
The AMS HT will eventually also be compatible with X-series and P-series machines. Both may require additional components such as a power supply.
The H2D expands the number of AMS units that can be used simultaneously with the X-series and P-series, supporting four AMS or AMS 2 Pro units plus eight AMS HT units.
This brings the total available spools per job to 24, although we haven't yet seen what this looks like and how it works in practice.
It will inevitably require additional hub-type hardware that Bambu Lab has not yet showcased.
As with the X-series and P-series, the AMS Lite is not compatible with the H2D due to differences in how the AMS Lite feeds and coordinates filament movement.
