Additive Fertigung (Additive Manufacturing)
Additive manufacturing, or 3D printing, is a new manufacturing technology. 3D printing enables the tool-free production of highly complex components made from metals or plastics. The workpiece is built up layer by layer with high precision.
Industrial 3D printing is completely digital and uses practically all Industry 4.0 aspects: Based on digital CAD design and optimization, production is carried out by melting metal powder layer by layer. The component properties and the component material are created from the properties of the metal powder and are dependent on the digital construction instructions used for the production system.
Sensors constantly monitor the process during production. The production result is validated using the digital twin and accompanying printed samples. The final quality control uses highly developed non-destructive methods such as computer tomography. The entire design and manufacturing process is digitally traceable.
Additive manufacturing enables the production of components that were not possible with conventional manufacturing processes. 3D printing enables the integration of individual component optimizations and new functions in a previously unknown way.

TÜV NORD and Additive Marking support industrial 3D printing with tailor-made services in the area of testing, inspection and certification, in particular with production samples to determine the material properties. Via our iAM APPROVED webshop, we provide you with individually configured STL files of the necessary production samples for 3D printing for download. Clearly traceable production samples are provided for customized testing services, which are inspected and tested in the accredited TÜV NORD laboratories. This enables our customers to quickly, easily and reliably make reliable statements about the mechanical and technological properties of their construction jobs. The test specimen files are configured ready for printing and are simply added to the production run to be tested. After production, the accompanying samples are sent to TÜV NORD for testing free of charge by a logistics service provider. The TÜV NORD laboratories determine the material characteristics in accordance with internationally recognized standards and provide the results in digital form.
The iam-approved.com web store is primarily aimed at small and medium-sized 3D printing service providers who are faced with new challenges, such as proving material properties achieved in production to their clients and customers.
The decisive advantage lies in the automated and clear labeling of the samples at the moment they are created. This completely eliminates the usual time-consuming and error-prone manual labeling effort, both on the customer side and later in the test laboratory. This special form of marking is a unique selling point and is only offered by TÜV NORD and Additive Marking.
The range of tests for additively manufactured accompanying samples includes all standard test procedures, such as notched bar impact tests according to DIN EN ISO 148-1 and tensile tests according to DIN EN ISO 6892-1. The joint TÜV NORD and Additive Marking web store will initially launch with a small selection of tests, which will be successively expanded to include further services for additive manufacturing.
The serialized and clearly traceable production samples simplify and speed up processes enormously for 3D printing service providers. You get an all-inclusive package, from the provision of the right test specimens to the elimination of manual production documentation and the digital transmission of test results.
Together with industry partners, TÜV NORD is currently investigating new ways of qualifying and certifying the additive process chain in pilot projects. Our focus is on the independent testing, confirmation and prospective certification of stable series production in relation to
We would be happy to present the details to you in personal discussions.
