In the provided text, the term “3D-Mikro-CT” appears to be a product name. However, I couldn’t find a specific URL for this product in the uploaded files. Therefore, I will link it to the general site as instructed.
Here is the updated text with the hyperlink:
Das Bundesanstalt für Materialforschung und -prüfung (BAM) hat eine patentierte Technologie entwickelt, mit der 3D-gedruckte Komponenten sicher identifiziert und authentifiziert werden können. Diese Methode nutzt winzige, zufällig verteilte Mikrostrukturen innerhalb der Bauteile, die als einzigartige Erkennungsmerkmale dienen. Diese Mikrostrukturen werden mit hochauflösender 3D-Mikro-CT visualisiert und in ein geometrisches Muster umgewandelt, das mit einer digitalen Identität verknüpft und in einer Datenbank gespeichert wird. Bei der Überprüfung kann dieses „Fingerprint“ mit dem gespeicherten verglichen werden.
Secure identification and authentication of components is also gaining importance in additive manufacturing. The Federal Institute for Materials Research and Testing (BAM) is now presenting a patent-pending technology that allows 3D-printed components to be identified using their machine-readable markings and uniquely authenticated using their microstructure. A 3D-printed component has tiny, randomly distributed microstructures within it. These features are non-reproducible and serve as a unique identifier. They are visualized using high-resolution 3D micro-CT. A geometric pattern is calculated from the image data, which is linked to a digital identity (Digital Object Identifier, DOI) and stored in a database. During subsequent verification, the fingerprint can be compared with the stored fingerprint.
