We've known since last year that Bambu Lab was about to release 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 pre-order price at US$1,899.
The H2D Combo, which includes the new AMS 2 Pro, will sell for US$2,199.
The H2D Laser Edition will be priced at US$2,799 or US$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, and its extensive features can be glimpsed 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 H2D's extruder.
It's called Dynasense, and unlike stepper motors, which move in fixed increments and, depending on the system they're implemented in, cannot re-transmit their position or missing position after skipping a step.
Bambu Lab's new motor can do just that, allowing the printer to better control filament flow.
Combined with Bambu Lab's typical algorithmic intelligence, this motor enables finer print extrusion quality, according to the company.
Sensors and cameras are located throughout the printer, from a dedicated nozzle camera for monitoring print inconsistencies and errors, to eddy current sensors for monitoring hotend alignment when switching; there are many unseen events happening to keep the H2D running smoothly.
Dual extrusion is a key feature, and the H2D's printhead has two parallel hotends.
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 control of the environment to maintain consistency for warp-prone materials.
The H2D can activate multiple openings on the printer, allowing cool air to enter and filtered air to be discharged.
This allows you to print PLA with the door closed.
Only 300-325 mm of the 350 mm print bed width is available for printing, which is often a disadvantage of dual-extrusion 3D printers.
Overall, you can use a build volume of 300-325 x 325 x 320 mm, with a fast-heating (to 120°C) print bed and a dual-sided textured PEI plate.
Bambu Lab has set the H2D's print speed at 1,000 mm/s and acceleration at 20,000 mm/s.
Technically, its maximum speed is twice that of the previous X1E, but it's unlikely to be used at this maximum speed in actual operation.
To improve 3D printing accuracy, Bambu Lab also offers an encoder board (sold separately).
This print-board-like sheet is covered with tiny machine-readable codes that the printer's camera can detect.
Combined with advanced calibration procedures, this sheet improves the H2D's movement accuracy to a deviation of less than 0.05 mm across the entire print area, with a 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 Edition, 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 functions 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 H2D Laser Edition devices are expected to begin shipping in April.
New AMS options
Launched today with the H2D is the AMS 2 Pro, a redesigned (but familiar-looking) AMS unit that integrates the much-requested filament drying function.
Bambu Lab claims that it does much more, featuring an intelligent ventilation system to expel humid air and sealing the unit to maintain the filament's condition.
The AMS 2 Pro can heat up to 65 °C 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 °C and rotate the spool during drying.
Unlike the AMS 2 Pro, which only transmits humidity messages via the printer and software, the AMS HT has a display that allows you to read the current humidity and the status of the drying operation at a glance.
Additionally, Bambu Lab notes that the AMS 2 Pro's filament feeding function is already present and can be used on X and P series machines, meaning partial backward compatibility.
The full drying function will be realized after a firmware update at an unspecified date.
The AMS HT will eventually also be compatible with X and P series machines. Both may require additional components such as power supplies.
The H2D expands the number of AMS units that can be used simultaneously with the X and P series, compatible with four AMS or AMS 2 Pro units plus eight AMS HT units.
This brings the total number of available filament axes per job to 24, although we haven't yet seen what it 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 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.
