Chinese 3D printer manufacturer Bambu Lab has launched the H2S, its new large-scale desktop 3D printer with built-in laser and digital cutting capabilities.
In March, Bambu released its highly anticipated H2D dual-nozzle 3D printer, which integrates laser engraving and vinyl cutting into an all-in-one desktop manufacturing unit. Earlier this month, the company introduced the H2D Pro, an enterprise-ready 3D printer featuring enhanced network security.
Now, the Shenzhen-based OEM has added the H2S to its growing lineup. The “S” highlights the system’s single-nozzle design, a departure from the H2D’s dual-nozzle architecture. Bambu’s new offering features a spacious 340 x 320 x 340 mm³ build volume that is 120% larger than the company’s popular X1C 3D printer. It also offers faster performance, reaching print speeds of up to 1000 mm/s and acceleration of 20,000 mm/s², 30% quicker than the X1C.
The H2S delivers impressive material versatility. Its 350°C hotend and 65°C heated build chamber allow the printer to handle a wide range of filaments, including standard and carbon- or glass-fiber reinforced PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, and PPS.
Additionally, the system supports offline operation, letting users control the printer, send files, and upgrade firmware without a cloud connection. It also features 23 sensors and 3 cameras that power an AI-driven monitoring system, capable of detecting defects and preventing print failures. Meanwhile, active motor noise canceling keeps operation under 50 dB, making the 3D printer ideal for small or shared workspaces.
Bambu Lab’s H2S is available in three configurations. The base H2S 3D printer lacks laser and vinyl cutting capabilities and ships without an AMS unit, while the H2S AMS Combo adds the AMS 2 Pro filament handling system. The H2S Laser Full Combo includes the AMS 2 Pro, 10W laser, and cutting modules, and is the only model equipped with an emergency stop button.
Bambu Lab’s base H2S is priced at $1,249 and will be available for order in October. The AMS Combo ($1,499) and Laser Full Combo ($2,099) are available now from the official Bambu Lab store.
Bambu Lab launches the H2S
Bambu Lab advertises the H2S as a “Go-To Personal Manufacturing Hub,” targeting makers, engineers, and manufacturers seeking high performance at a competitive price. The system features a 350°C hotend and a 65°C actively heated chamber, supported by closed-loop fan control and advanced thermal management to reduce warping and improve layer adhesion when printing with engineering filaments.
It also integrates servo motor sensors and high-resolution eddy current sensors on the hardened steel nozzle. These monitor nozzle pressure and automatically calibrate PA parameters for each filament, producing parts with smooth surfaces and sharp edges, according to Bambu Lab.
The company’s proprietary PMSM servo system checks resistance and position data 20,000 times per second, adjusting torque in real time to stabilize extrusion and instantly detect grinding or clogs. Filament path sensors track feeding speed and position to identify tangles and monitor material usage, while five NTC temperature sensors in the nozzle, heatbed, and chamber regulate internal conditions to maintain an optimal 3D printing environment.
The base and AMS Combo systems both include a Live View Camera and Toolhead Camera, while the Laser Full Combo also adds a BirdsEye Camera to the mix. Together, these support AI-driven visual monitoring that can detect clumping, spaghetti, and purge chute jams, allowing users to stop print jobs before they fail.
Bambu’s proprietary Vision Encoder is available as an optional upgrade for an additional $105. Once installed, the H2S can achieve distance-independent motion accuracy under 50 μm. During calibration, the encoder automatically compensates for mechanical drift, ensuring consistent precision throughout print jobs.
The H2S also delivers faster 3D printing speeds, unlocking greater productivity and efficiency. Its extrusion system provides 67% more force than standard stepper motors, enabling high filament flow. According to Bambu, the H2S maintains print quality at these elevated speeds, thanks to its active vibration compensation technology. This system neutralizes vibrations and resonance during operation, reducing the effects of rapid toolhead movements.
The H2S also offers automatic hole and contour compensation when printing with designated Bambu Lab filaments. According to the company, this feature delivers “machine-shop-level precision for hole dimensions,” making it well-suited for functional parts with tight tolerances.
Like the H2D, the H2S’s 10W laser can cut through up to 5 mm of plywood, acrylic, or PU. Its cutting module works with materials such as paper, vinyl, and PU leatherette, while the pen attachment lets users create linework, sketches, or handwritten notes.
The Bird’s-Eye camera and toolhead camera enable live spatial alignment, letting users preview the toolpath with 0.3 mm accuracy. The system also automatically arranges designs to maximize material efficiency.
To ensure safe operation with its 10W laser, the H2S includes a laser-safe window that protects the user’s eyes from the 455 nm beam. Five flame sensors monitor and alert users to fire risks, while the Full Laser Combo adds an emergency stop button for an extra layer of safety.
Bambu Lab has also designed the H2S with digital safety in mind. While it supports cloud connectivity, the 3D printer can run offline for security-sensitive applications. It also features Developer Mode, which unlocks MQTT port access and allows users to integrate third-party components and custom software into their 3D printing operations.
