Three-dimensional printing (3DP) has revolutionized the way we design and manufacture products. However, the increasing reliance on 3DP has also raised concerns about the security of this technology. The 3DP process involves the use of complex software, networked devices, and intricate supply chains, which create potential vulnerabilities that can be exploited by attackers. In particular, the risk of contamination or sabotage of the printing process can have serious consequences, including compromised product quality, safety risks, or even malicious modifications to the printed product.
Our results show that the PIH is effective in preventing these types of attacks, ensuring the security and integrity of the 3D printing process. printisolationhost
In this paper, we proposed the concept of a print isolation host (PIH) as a novel approach to enhance the security of 3D printing. The PIH provides a dedicated host system that isolates the 3D printing process from potential sources of contamination. Our design and implementation of a PIH demonstrate its effectiveness in preventing various types of attacks. We believe that the PIH is an essential component of a secure 3D printing infrastructure. In particular, the risk of contamination or sabotage
In some environments, such as those using the HP Universal Print Driver, you may notice new instances of PrintIsolationHost.exe appearing for every print job. This process is designed to recycle itself occasionally based on idle timeouts or the number of objects handled. 3. Application Errors and Crashes The PIH provides a dedicated host system that
