Abstract: Reducing transportation dependencies and enhancing supply chain transparency is critical in times of crisis and growing sustainability demands. This paper investigates integrating blockchain technology, 3D printing, and Digital Product Passports (DPPs) to develop a secure, modular system for managing, sharing, and tracking product data throughout its lifecycle. Two use cases illustrate the system’s practical application: 3D printing in the fashion industry and spare parts management. In both cases, the DPP is integrated into a webshop, enabling users to seamlessly purchase products, access individualized 3D print files, and customize designs to suit their preferences. Blockchain technology ensures data integrity, combats product counterfeiting, and provides transparent supply chain information. The system enables secure, on-demand production while protecting intellectual property by linking products to unique licenses and encrypted 3D print files. This paper details the underlying data model that supports these use cases and explores the broader opportunities and limitations of using blockchain-based systems for additive manufacturing.
Keywords: NFT, 3D print, Transparency, Blockchain, Digital product passport, Fashion, Spare parts.
