Securing 3D Printing: Understanding the Hidden Risks of G-Code Manipulation in Additive Manufacturing
Abstract: 3D printing has become a cornerstone of modern manufacturing, enabling rapid prototyping, distributed production, and innovative applications across various industries. However, as additive manufacturing (AM) systems become more interconnected, they are increasingly vulnerable to cyber threats. One of the most critical yet underexplored threats is G-code injection attacks malicious modifications to the machine-readable instructions that control 3D printers. Attackers can alter G-code to introduce structural weaknesses, embed hidden malware, or sabotage printed components without detection. This whitepaper examines the risks posed by G-code manipulation, presents real-world case studies, and explores mitigation strategies to enhance cybersecurity in additive manufacturing.
