DNV GL grants first maritime 3D printing approval

A probehead for taking gas samples in hot gas atmosphere, produced at the thyssenkrupp TechCenter Additive Manufacturing. It is additive manufactured from austenitic heat resistant steel, and has a longer service life due to integrated cooling channels (Source: thyssenkrupp).

As additive manufacturing begins to gain traction in the maritime field, DNV GL has issued its first Approval of Manufacturer certificate to the thyssenkrupp TechCenter Additive Manufacturing in Mülheim an der Ruhr, Germany.

The approval is important for thyssenkrupp Marine Systems which is working closely with a range of international customers on the integration of 3D-printed parts for ships and subsea craft. 3D printing, experts believe, has the potential to transform aspects of ship construction and through-life maintenance, reducing lead times and stock requirements, resulting in significant environmental benefits.

Geir Dugstad, director of Ship Classification and technical director of DNV GL – Maritime, commented: “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. We are very pleased to certify that the thyssenkrupp TechCenter Additive Manufacturing has demonstrated its ability to reliably produce metallic materials using additive manufacturing.”
