Using Blockchain to Protect 3D Printing from Unauthorized Model Tampering

As three-dimensional (3D) printing technology is widely used, security issues have arisen, especially in the terminal parts of automobiles, aircraft, and 3D-printed military equipment. If original design models or STL (stereolithography) files are hacked tampered, severe consequences can be anticipated. In this paper, we propose a demonstration to use high-throughput blockchain store “fingerprints” 3D model verify before prevent illegal tampering. Relying on tamper-resistant features blockchain, credibility components ensured. The combination will help people build trusted manufacturing environment realize more flexible for future industry.
