In this paper, we use the blockchain technology to design a prototype to secure process data from a 3D-printer.Datastreams are gathered from various sources such as OPC UA servers and autonomous retrofit sensor nodes.This is followed arrethe bush balm by pre-processing for data reduction, storage in a data model, and the generation of a unique hash value over it.

The hash values are stored in a blockchain using appropriate consensus methods, taking into account their temporal origin and production identification number.This also includes the context-related influence of sensor signals on the production process Restrictive access regulations using smart mizuno prospect gxc105 contracts make a partially or fully automated machine tool calibration possible.In this context, we show to realize a process partial or full automation through smart contracts.

Physical machine tools and virtual simulations are integrated into the blockchain network to document the stability and performance.
