In response to the pervasive adoption of three-dimensional (3D) printing technology, a pressing concern has arisen within critical sectors, notably automotive, aerospace, and military applications. This concern stems from the potential vulnerabilities associated with compromised original design models or STL (stereo lithography) files, which could yield severe consequences. This research paper introduces a demonstrative methodology that harnesses a high-throughput blockchain system for the purpose of recording and authenticating 3D models prior to the commencement of the printing process. By doing so, it aims to mitigate the risks inherent in unauthorized alterations. It is worth emphasizing that blockchain technology is instrumental in safeguarding sensitive information during exchanges between various network peers. This solution capitalizes on the inherent tamper-resistant properties intrinsic to blockchain technology, thereby fortifying model security and elevating the trustworthiness of resultant end-use components.

This collaborative approach holds the potential to not only enhance security but also facilitate agile and efficient production in future industrial landscapes. An ecosystem for safe manufacturing might be established if blockchain technology and 3D printing come together, with the prospect of facilitating agile production in future industrial landscapes. In this body of work, we present a blockchain-based 3D printing framework, meticulously designed to encapsulate the intricate interactions among diverse nodes within the blockchain network.

摘要

In response to the pervasive adoption of three-dimensional (3D) printing technology, a pressing concern has arisen within critical sectors, notably automotive, aerospace, and military applications. This concern stems from the potential vulnerabilities associated with compromised original design models or STL (stereo lithography) files, which could yield severe consequences. This research paper introduces a demonstrative methodology that harnesses a high-throughput blockchain system for the purpose of recording and authenticating 3D models prior to the commencement of the printing process. By doing so, it aims to mitigate the risks inherent in unauthorized alterations. It is worth emphasizing that blockchain technology is instrumental in safeguarding sensitive information during exchanges between various network peers. This solution capitalizes on the inherent tamper-resistant properties intrinsic to blockchain technology, thereby fortifying model security and elevating the trustworthiness of resultant end-use components. In addition to addressing immediate security concerns, the paper envisions the establishment of a broader ecosystem for safe manufacturing through the integration of blockchain technology and 3D printing. This collaborative approach holds the potential to not only enhance security but also facilitate agile and efficient production in future industrial landscapes. An ecosystem for safe manufacturing might be established if blockchain technology and 3D printing come together, with the prospect of facilitating agile production in future industrial landscapes. In this body of work, we present a blockchain-based 3D printing framework, meticulously designed to encapsulate the intricate interactions among diverse nodes within the blockchain network.
