The objective of PROSTEP's Blockchain workshop is to provide customers with a basic understanding of how blockchains work, to describe the software architecture, network infrastructure and setup of a possible implementation, and to identify a concrete application scenario in their company. The Secure Additive Manufacturing Platform, developed within the framework of the SAMPL project, provides an example of a successful implementation. It is an end-to-end security solution that covers the entire process from creating the digital 3D print data to exchanging the data with 3D print service providers right through to tagging the printed components using blockchain technology.
