thyssenkrupp TechCenter Additive Manufacturing is the first 3D printed parts for the maritime sector manufacturer in the world to win DNV GL certification.

The certificate means that thyssenkrupp TechCenter Additive Manufacturing is an approved supplier for maritime and general industrial applications.

The approval covers the 3D printing and processing of austenitic stainless steel parts.
The certification was also awarded for the acceptance process in accordance with European Standard (EN) 10204 and the associated product information such as the chemical and physical material characteristics.

thyssenkrupp Marine Systems works closely together with international customers on the integration of additive manufactured parts on ships and submarines and, therefore, requires parts with acceptance test certification.

So far, there have been no procedures and processes for this worldwide, but these have
now been developed in close collaboration with thyssenkrupp TechCenter Additive

DNV GL  is the world’s leading classification society and a recognised advisor for the
maritime industry.

DNV GL director of ship classification and technical director Geir Dugstad said: “Additive manufacturing will have a significant impact on the future maritime value chain. Producing components that have the same level of quality as conventionally manufactured parts and fulfil class requirements is key.

“At DNV GL, we are very pleased to certify that the thyssenkrupp TechCenter Additive Manufacturing has demonstrated its ability to reliably produce metallic materials using additive manufacturing.

“This is the first time DNV GL has awarded its approval of manufacturer certificate for additive manufactured metallic materials, and I would like to congratulate thyssenkrupp AG on this outstanding achievement.”
