ThyssenKrupp Marine Systems has secured approval from DNV GL to integrate additive manufactured parts on ships and submarines.

The company obtained approval after identifying a need for parts with acceptance test certification.

Thyssenkrupp developed the 3D manufacturing procedures in collaboration with thyssenkrupp TechCenter Additive Manufacturing.

With the additive manufacturing certificate from DNV GL, thyssenkrupp TechCenter Additive Manufacturing becomes an approved supplier of 3D printed parts for maritime and general industrial applications.

The approval awarded to the company covers austenitic stainless steel parts.

In addition, DNV GL awarded certification for the acceptance process and associated product information.

DNV GL Maritime 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.”

3D printing technology is expected to reduce lead times, costs, and stock requirements.

thyssenkrupp Marine Systems chief operating officer Dr Luis Alejandro Orellano said: “We are delighted that with thyssenkrupp TechCenter Additive Manufacturing we now have a certified partner who can supply thyssenkrupp Marine Systems with additive manufactured parts that meet both our own and our customers’ high expectations.

“Together we are putting innovative solutions into our submarines and ships, setting new standards for the navy of the future.”
