[3D Printing] Bambu Lab's new "Trust Center" lists everything it does to protect 3D printers
In an industry usually reticent about security issues, Bambu Lab has finally revealed its complete code of conduct.
Here's what this new transparency means for you and all other 3D printer users.
Here's what this new transparency means for you and all other 3D printer users.
China-based Bambu Lab is addressing data security and privacy concerns for desktop 3D printers with an extremely transparent stance: a new online "Trust Center."
This public center details the full depth of Bambu Lab's security architecture – from hardware-level encryption to third-party data storage – although not all measures are enabled on every printer.
While other professional consumer 3D printer manufacturers also implement security protocols, they rarely make them public.
Bambu Lab's approach sets a new benchmark.
By publicly detailing its measures, obtaining ISO and TRUSTe certifications, and providing user-centric granular privacy controls, the company is enhancing security and transparency across the entire 3D printing market.
As stated in our news "Is your 3D printer at risk of security?" a few days ago, "You might be surprised," security has become a hot topic in the desktop 3D printer space, not because of a surge in new 3D printer hacks (yet), but because industries already suffering from persistent desktop issues (such as aerospace, defense, and large multinational corporations).
These users want more robust security for their machines, especially when they are on a corporate network.
"Users should understand exactly how their printers and data are protected," said Ye Tao, CEO of Bambu Lab.
"The Trust Center demystifies this. We are making our security practices, certifications, and ongoing efforts fully transparent so that users can make informed decisions about their devices."
Hardware Security as a Foundation
For most consumer users, these features may be overly detailed.
Bambu Lab has these security features, but they have never been described in such detail before.
Most notably, the security features of your Bambu Lab 3D printer (depending on the model) are roughly the same as your phone or laptop, with all data for customers outside China stored in Amazon Web Services servers located in the United States.
The 38-page security development whitepaper released by Bambu Lab does not use vague terms, but instead details specific enterprise-grade security technologies at the hardware and software levels.
The whitepaper also discloses how your data will be used, by whom, and how to contact the company with data deletion requests.
In the whitepaper, Bambu Lab states: "We firmly believe that only by fully respecting and protecting user data security and privacy can we win the lasting trust of users.
We will continue to increase investment in this area, work with the security community with an open and cooperative attitude, improve the security of our products and services, and listen to user feedback with respect."

Software Security
The most important aspect of this publication is its focus on security built directly into the silicon, a practice common in smartphones and enterprise devices but less so in consumer 3D printers.
Trusted Execution Environment (TEE): X1 and H2 series printers utilize ARM TrustZone technology, which is a key differentiator from other desktop FDM 3D printers.
This technology creates a hardware-isolated "secure world" on the processor for handling the most sensitive operations, such as key management and firmware decryption.
This ensures that even if the main operating system is compromised, the printer's most critical security features remain protected.
Secure Boot and Verified Boot: All Bambu Lab printers support Secure Boot, which uses a hardware "root of trust" to verify the authenticity of the printer's software, one by one, from the moment the printer boots up.
The high-end X and H series also add Verified Boot, which checks if the file system has been tampered with.
This is crucial for preventing the installation of persistent malware or unauthorized firmware.
Encrypted Storage with Hardware Keys: Storage is encrypted using keys protected by the hardware itself.
In the P1 and A1 series, keys are stored in Efuse, so only the hardware security engine can read them.
This prevents attackers from physically removing the storage chip and reading the data within.

Advanced System and Kernel Hardening
Beyond hardware, Bambu Lab also details specific, advanced software defenses to protect the printer's operating system during runtime.
Mandatory Access Control (MAC): AppArmor is used on high-end models (currently H2C, planned for all X/H2 series) to restrict applications to a strict set of rules, limiting the damage that exploited applications can cause.
Kernel Address Space Layout Randomization (KASLR): This feature, also applied to high-end models, randomizes the location of the printer's kernel software in memory every time it boots.
This makes it more difficult for attackers to execute common exploits that rely on knowing the exact location of the kernel in memory.
Direct User Privacy Controls
Despite all the security measures mentioned above, the most secure 3D printer is still one that does not communicate at all.
The Bambu Lab X1E and H2C are equipped with physical network switches that completely cut off the machine's connection to local and Wi-Fi networks.
LAN-only Mode: Some Bambu Lab printers (X1E and the upcoming H2C) offer a "LAN-only mode" where the printer does not initiate any external connections, and all communication takes place securely on the local network.
This directly serves users with strict privacy or security requirements.
Offline Updates: Crucially, the company provides a secure firmware update method using an SD card for users in LAN-only mode. This allows users to remain completely offline while still accessing new features and security patches.
Developer Mode for Print Farms: In direct response to feedback from commercial users, Bambu Lab has added "Developer Mode" to the "LAN-only mode."
This allows third-party management software, common in print farms, to bypass certain new authorization controls and continue to operate normally, demonstrating its willingness to actively adapt to the needs of professional users.
Independent Certifications Obtained
Bambu Lab also announced that it has obtained three internationally recognized certifications in 2025 after extensive third-party audits.
ISO/IEC 27001 (Information Security Management): Certified on April 11, 2025, this standard confirms that the company meets strict international requirements for protecting information assets.
ISO/IEC 27701 (Privacy Information Management): Also certified on April 11, 2025, this demonstrates alignment with global privacy protection frameworks.
TRUSTe Enterprise Privacy: Certified in July 2025, this indicates that the company's privacy management system complies with established international standards.
Find Bambu Lab Vulnerabilities, Win a Bounty
The company's ongoing security work includes a bug bounty program that has been active since 2023.
To date, 51 security researchers have participated in the program to help identify and resolve potential vulnerabilities.
The Bambu Lab Bug Bounty Program invites security researchers to find and report vulnerabilities in the company's products and services, and offers rewards.
Participants can find potential security issues and submit detailed reports via email to security@bambulab.com.
The company team will verify submitted reports, and if the reports are true and valid, rewards will be issued based on the severity of the vulnerability.
The program covers web applications (e.g., bambulab.com and makerworld.com), the Bambu Handy mobile app, PC software including Bambu Studio, and firmware for X1, P1, H2, and A1 series printers.
Vulnerability levels range from low to high, with the most severe threats including remote device control or bypassing secure boot mechanisms.
Response times and monetary rewards depend on the severity of the vulnerability.
All participants must adhere to strict rules of engagement, including respecting user privacy, not disrupting services, and responsibly disclosing vulnerabilities only after the Bambu Lab team has fixed them.
The new Trust Center is now live on the Bambu Lab website, including downloadable whitepapers, certification documents, and detailed information about the Bug Bounty Program.
