The H2S Laser Full Combo is the Bambu Lab H2S with the optional 10 W laser and cutting module added: a 340 x 320 x 340 mm enclosed printer with a 350 degrees C hotend, a 65 degrees C heated chamber and the AMS 2 Pro. It is for makers and small businesses that want big, fast prints plus laser cutting and engraving in one machine.
Editor's Choice. Praises the large 340 x 340 mm bed, enclosure, perfect auto bed levelling and the faster, easier-to-maintain AMS 2 Pro, with clean results in PLA, PETG, nylon-CF and TPU. Downsides: the price and proprietary replacement parts. Tested the AMS Combo without the laser.
“The H2S has excellent quality and print speed, making it the perfect successor to the X1C.”
Rates the single-nozzle H2S for its huge 340 x 320 x 340 mm volume, speed and enclosed heated chamber, scoring 29/30 on his print-quality test. Cons: no dual nozzle, higher running cost from the heated chamber and an optional Vision Encoder.
“A single nozzle might seem like a step back for industrial and business users, but this machine offers enterprise-level print features and volume at an extremely affordable price.”

Uses two H2S units (supplied by Bambu Lab) across a variety of materials for weeks and reports no bugs, errors or clogs, with good prints out of the box. Calls it the bigger Bambu he wanted. Filament sponsor: Polymaker.
CNC Kitchen · 2025年8月26日
Compares the H2S with the H2D: same look and a little more volume, $800 cheaper, but single-nozzle purge waste and no real multi-material. Still a hybrid with the 10 W laser and drag knife only. Calls it a fantastic choice for single-material parts that need the volume.
Made with Layers · 2025年8月26日
Thomas Sanladerer sees the H2S as more of a bigger X1C than a baby H2D. He misses the second hotend for multi-material work, but finds little to complain about, with very well-designed hardware and near-flawless prints at a fair price. Sponsor: VoxelPLA.
何时选择Bambu Lab H2S Laser Full Combo
Choose the Laser Full Combo if you want the H2S's large, enclosed single-nozzle printing and also plan to cut or engrave: Bambu lists the laser module as optional and self-installed, so the base H2S is cheaper if you will not use it. Reviewers agree on the printing: Tom's Hardware gave it 4.5/5 and called it the successor to the X1C, and TechRadar also gave 4.5/5. If you want real multi-material with soluble supports, the dual-nozzle H2D suits better, as CNC Kitchen and Made with Layers note the single nozzle wastes filament on colour changes.
优点
A 340 x 320 x 340 mm enclosed volume with a 350 degrees C hotend and a 65 degrees C heated chamber (Bambu Lab).
Excellent print quality and speed with perfect auto bed levelling (Tom's Hardware); Frankly Built ran two units for weeks with no clogs or errors.
The 10 W 455 nm laser cuts up to 5 mm plywood, acrylic or PU, and the module adds air assist and digital cutting (Bambu Lab).
The AMS 2 Pro is faster and easier to maintain (Tom's Hardware), with clean results in PLA, PETG, nylon-CF and TPU.
Five flame sensors, a laser safety window and an emergency stop (Bambu Lab).
Works with SimplyPrint through the SimplyPrint Client, verified.
缺点
Single nozzle, so colour changes purge filament and there is no real multi-material; a second hotend is the H2D (CNC Kitchen, Made with Layers).
Expensive, with proprietary replacement parts (Tom's Hardware), and a higher running cost from the heated chamber (TechRadar).
The laser module needs self-installation, and a laser in a shared room needs supervision and safety rules (Bambu Lab).
It runs through Bambu Lab's own software and cloud, which some organisations' compliance rules don't allow; connected through SimplyPrint it can be cut off from that and use SimplyPrint's European cloud.
适合谁
学校可用
Enclosed, filtered and well protected, and SimplyPrint can queue student prints for approval, but the price and the laser module need supervision.
业余爱好者非常适合
Large, fast, reliable prints plus laser cutting and engraving, at a price that is high but fair for what it does.
企业非常适合
A large heated chamber for engineering filaments, verified SimplyPrint support, and laser cutting for enclosures and jigs.
打印农场可用
Reliable per Frankly Built's two-unit test, but a large, costly single-nozzle machine with no plate-clearing kit in our sources.

Bambu Lab is a Shenzhen company founded in 2020 by former DJI engineers. It makes FDM printers in four families (A, P, X and H), the AMS multi-material units, the Bambu Studio slicer, the Bambu Handy app and the MakerWorld model site, and designs them to be used together. Its printers are used by beginners, hobbyists, schools and print farms.

Bambu Lab works like Apple: printer, slicer, app, cloud and multi-material system come from one company and are made to work together. Filament and slicer choice stay open, but the firmware is closed and signed, and since 2025 third-party control needs Bambu Connect or the unsupported Developer Mode.
固件和自定义固件 ●●●●●
The printer firmware is Bambu's own and closed; in 2022 Bambu said it would keep it in-house. Its security white paper describes secure boot that only runs verified firmware on X1, H2, P1 and A1 printers. Bambu publishes the GPL parts it uses (Linux kernel, U-Boot, BusyBox) but not the printer software. Rooting the X1 only became possible through a security flaw the X1Plus project used in 2024; Bambu then published a one-off rootable X1 firmware for owners who give up their warranty, and blocks rooting in later firmware.
[1][2][3][4][22]
本地控制与集成 ●●●●●
LAN Only mode prints and monitors from Bambu Studio or Bambu Connect without internet or an account; the Handy app, printing from outside the network and print history need Bambu's cloud. Since the 2025 authorization firmware, other software can only read status in normal mode. Full control needs Developer Mode, which cuts the cloud link and which Bambu says it cannot support because the protocols are not official. Bambu documents no local protocol; it offers a file hand-off to Bambu Connect and a Local Server SDK on application.
[23][24][6][7][5]
第三方耗材、切片软件和零件 ●●●●●
Third-party filament works, and Bambu publicly denied in 2025 that it would restrict it. OrcaSlicer and other slicers can be used, but since the 2025 firmware they send and control prints through Bambu Connect or Developer Mode. Hotends are Bambu's own designs, and Bambu says it cannot promise long-term support for accessories that control the printer unless it approved them first.
[7][6][4]
维修和备件 ●●●●●
Bambu's store sells individual spare parts down to motors, belts, encoders and boards, and its wiki has step-by-step replacement guides for each model (for example the P2S hotend and the H2D/H2C AP board). Many parts, hotends included, are Bambu-specific, so spares come from Bambu.
[8][9][10]
数据与隐私 ●●●●●
Cloud features need a Bambu account, while LAN Only mode keeps jobs on the local network. Bambu publishes a Trust Center and a 38-page security white paper, says it holds ISO/IEC 27001, ISO/IEC 27701 and TRUSTe certifications, and runs a paid bug bounty. In August 2023 a cloud outage made some printers start earlier jobs on their own; Bambu apologised.
[2][11][5][12]
社区和文档 ●●●●●
Very large user community, the MakerWorld model site, a detailed wiki and a blog where Bambu explains its policy changes. Bambu Studio is developed in public on GitHub with an open issue tracker. The printer protocol is not documented, and Developer Mode is unsupported.

Publishes security certifications and runs a public bug bounty.
缺点
Firmware is closed and signed; current models have no supported way to run custom firmware.
Since the 2025 firmware, third-party software and accessories need Bambu Connect or the unsupported Developer Mode to control the printer.
Remote printing, the Handy app and print history depend on Bambu's cloud.
Hotends and many parts are Bambu-specific, so spares come from Bambu.
In 2026 a US jury found the X1, P1 and A1 infringe Stratasys patents; Bambu is appealing.
实绩
九月 2026: A US federal jury in Texas found that Bambu Lab's X1, P1 and A1 printers infringe Stratasys patents on prime towers and bed levelling, and awarded Stratasys $27.6 million. No injunction was placed on the printers. Bambu told Tom's Hardware it disagrees with the verdict and intends to seek post-trial review and appeal. Stratasys had filed two suits in 2024; more patents are still to be decided.

五月 2026: Bambu Lab pressed the developer of 'OrcaSlicer-bambulab', a fork that restored direct cloud printing from OrcaSlicer, to remove it, according to Manufactur3D. On 7 May Bambu said the fork impersonated the official Bambu Studio client to its cloud, which its user agreement does not allow, and that modifying and sharing its AGPL code remains fine. The developer disputed the claims.
[15][16][17]
十月 2025: Bambu Lab opened a Trust Center with a security white paper and listed ISO/IEC 27001, ISO/IEC 27701 and TRUSTe privacy certifications. A year later it said its bug bounty had worked with over 100 researchers and that it had added a public security update log.
[2][11]
2025年1月20日: After criticism from users and print farms, Bambu Lab announced an optional Developer Mode for X1, P1, A1 and A1 mini that leaves MQTT, FTP and the live stream open for third-party software in LAN mode, without official support. It also said LAN mode via Bambu Connect needs neither internet nor an account, and that third-party filament would not be restricted.
[7]
2025年1月16日: Bambu Lab announced firmware with 'authorization control', first for the X1: starting prints, moving axes, changing temperatures and binding the printer now require Bambu-approved software, also in LAN mode. On updated printers, third-party slicers and accessories such as the Panda Touch could no longer control the printer except through Bambu Connect; reading status still worked. Bambu cited security and up to 30 million unauthorised cloud requests a day; older firmware stayed optional.
[6]
三月 2024: After the X1Plus jailbreak, Bambu Lab published a one-off rootable firmware for the X1 series for owners who give up their warranty support. It said it does not support X1Plus, and that firmware after it would block rooting again.
[4]
二月 2024: Bambu Lab extended its A1 heatbed-cable callback to a recall of all A1 printers and asked owners to stop using them. It reported electrical faults in under 0.1% of units and offered a full refund plus an $80 voucher, or a redesigned heatbed plus a $120 voucher and six extra months of warranty. The A1 mini was not affected.
[18][19]
一月 2024: Community developers rooted the X1 series through a security flaw in its firmware (up to version 1.07) and released the X1Plus custom firmware. Bambu Lab closed the flaw in later firmware.
[22]
八月 2023: During a Bambu cloud outage on 15 August 2023, some printers started print jobs without user action, because jobs stuck in the cloud were resent when service returned. Bambu apologised, took responsibility and said it would add checks before a print starts.
[12]
五月 2022: Before its first printers shipped, Bambu Lab said its firmware would stay closed and in-house to remain competitive, and promised to open-source everything if the company ever could not survive.
