3D-Chain is an open-source protocol based on collections of smart contracts which aims to become the key ecosystem for manufacturers, designers and customers. It provides a coordinated decentralized network based on 3D Printing technology and will expand to other manufacturing environments. Within this framework, the benefits of manufacturing and 3D Printing become a global common infrastructure for all. Anyone can access the network, become a stakeholder in its development, add a fabrication technology (e.g. 3D Printer) to 3D-Chain’s ecosystem, add a new design or customize existing one, and receive network payment tokens in exchange.
