Bambu Lab releases comprehensive security and privacy policy for 3D printing systems

Chinese 3D printer manufacturer Bambu Lab has introduced the “Trust Center,” a central platform for security and data protection information. The company is responding to previous criticism of inadequate security measures and wants to create transparency about its technical protection mechanisms. The Trust Center bundles technical documentation, certifications, and guidelines relating to the handling of user data and the protection of device infrastructure.

The focus is on a 38-page white paper that describes the security architecture of Bambu Lab products in six areas: device security, software security, cloud protection, data protection compliance, open source initiatives, and a bug bounty program. According to Bambu Lab, significant resources have been invested in these areas over the past three years to systematically close security gaps.

The company relies on hardware-based security for device security. Models in the X1 and H2 series feature secure boot processes that verify firmware before it is executed. Hardware-level encryption engines and trusted execution environments are designed to prevent sensitive keys or processes from being compromised. The more affordable P1 and A1 printers use flash-based AES-XTS-256 encryption and store security keys in an isolated Efuse structure.

Bambu Lab has also introduced measures on the software side to make manipulation more difficult. These include code signing, anti-debugging mechanisms, and regular security updates. Cloud services are secured by multi-layered protection systems, including DDoS defense, web application firewalls, and encrypted communication protocols such as HTTPS and MQTTS. Users can also operate their devices completely offline—a so-called “LAN-only mode” enables operation without a cloud connection.

Bambu Lab refers to three independent certifications: ISO/IEC 27001 for information security management, ISO/IEC 27701 for data protection management, and the TRUSTe privacy seal. These are intended to demonstrate compliance with international standards and data protection guidelines such as the GDPR.
