Bambu Lab's Trust Center is now live at bambulab.com/trust-center. Users can download the security white paper, access certification documents, view privacy policies, and find developer integration information.

Bambu Lab, a high-performance 3D printer manufacturer, has officially launched its Trust Center public resource platform, fully disclosing its security and privacy practices to global users. The release coincides with the company's first security white paper and its attainment of three internationally recognized certifications: ISO/IEC 27001, ISO/IEC 27701, and TRUSTe Enterprise Privacy.

Bambu Lab's Security Defense System

Bambu Lab states that the purpose of creating the Trust Center is to "provide users with clear information on how 3D printers, data, and creative works are protected." This initiative includes detailed technical documentation, certification records, and developer resources, reflecting the company's commitment to transparency and long-term trust in interconnected manufacturing systems.

Dr. Tao Ye, CEO of Bambu Lab, said, "Users have the right to know exactly how their printers and data are protected. We are ensuring complete transparency regarding our security practices, certifications, and ongoing efforts so that users can make informed decisions about their devices."

Hardware-Level Security Across Printer Lines

The accompanying security white paper outlines a multi-layered protection strategy covering hardware, software, and cloud infrastructure. At the device level, each printer integrates a hardware-based security engine for cryptographic operations.

High-end models like the X1 and H2 series utilize ARM TrustZone technology, partitioning critical functions into secure and normal processing environments. These measures include Replay-Protected Memory Blocks (RPMB) and flash-based AES encryption. Additionally, a secure boot process with a verified boot sequence ensures firmware has not been tampered with, preventing unauthorized access. Debug ports are permanently disabled at the factory to eliminate potential attack vectors.

Bambu Lab states that this combination of hardware and software defenses brings user device security "closer to the standards of industrial IoT systems than typical desktop printers."

Network and Cloud Protection

All Bambu Lab devices communicate using encrypted protocols, including HTTPS, MQTT, DTLS, and WPA2-Enterprise Wi-Fi. Furthermore, users can opt for a LAN-only mode, disabling all external connections for offline printing. Firmware can also be updated via offline SD card installation, offering isolation for users who prefer fully local operation.

The company's cloud infrastructure is distributed across Amazon Web Services (USA) and Alibaba Cloud (China), protected by Cloudflare's global Web Application Firewall and DDoS protection. Data is encrypted both at rest and in transit, passwords are hashed using Argon2, keys are managed by a dedicated Key Management System (KMS), and access is constrained by strict least-privilege policies.

User accounts also support two-factor authentication and one-click logout, while Bambu Lab's internal and third-party penetration testing ensures compliance with ISO/IEC 27001 and GDPR standards.

User Privacy and Control

The white paper emphasizes giving users direct control over data collection and connectivity. Privacy tools such as Stealth Mode Printing, browsing history, and the User Experience Program toggle allow users to decide whether data is stored locally or in the cloud. Diagnostic log exports use AES encryption, and any logs uploaded for technical support are automatically deleted 14 days after the issue is resolved.

Enterprise-grade models like the H2D Pro include a physical network switch to completely disable wireless connectivity, meeting stringent security requirements in professional environments.

Bambu Lab views these measures as part of an "open and collaborative" privacy approach, stressing that user control, transparency, and international compliance form the cornerstone of the company's long-term trust strategy.

Open Source and Security Collaboration

Bambu Lab also reiterated its commitment to the open-source community. The company not only maintains a public index of open-source software but also hosts its slicer software, Bambu Studio, on GitHub. This practice actively adheres to the license requirements of projects like RepRap, Marlin, and Klipper.

Since its launch in 2023, the company's bug bounty program has successfully engaged 51 security researchers and awarded tens of thousands of dollars in rewards along with multiple 3D printers to those who discovered vulnerabilities. As the security team stated in the report, "Security is not a destination, but a journey of continuous improvement."
