Share Blockchain and Additive Manufacturing: Can the Two be Combined? Yes, they can. And we have demonstrated this within the framework of the SAMPL project. For almost three years PROSTEP, together with seven partners, has been developing an end-to-end solution for the forgery-proof exchange of 3D print data. The key to this is the use of blockchain, or distributed ledger, technology. On 10 October 2019, we will be presenting the project results at a user conference being held at the Center of Applied Aeronautical Research (ZAL) in Hamburg.
