TMS to Use 3D Printers for Submarines

Marine Systems (TMS) plans to use 3D printers increasingly in manufacturing submarine parts. This offers decisive advantages over conventionally produced components.The corresponding quality and safety approvals have already been granted. Through acquisition of the thyssenkrupp TechCenter Additive Manufacturing (in Mülheim an der Ruhr, North Rhein-Westphalia), the required technology and expertise will now come to the Kiel Fjord. It is planned to complete the transition by June 2020.Dr. Luis Alejandro Orellano, COO of thyssenkrupp Marine Systems said: "3D printing opens up completely new

Thyssenkrupp Wins 3D Printing Approval

The international accredited registrar and classification society DNV GL has awarded thyssenkrupp, German multinational conglomerate, first additive manufacturing  approval of manufacturer certificateThe shipping industry is looking to take advantage of additive manufacturing (AM), also known as 3D printing, to print spare parts, thereby reducing lead times, costs, stock requirements, and environmental impacts. Certification ensures that AM part users can have the same confidence in an additive manufactured product as a conventionally produced one.The newly issued certificate makes the thyssenkrupp

demand for its services, driven by growth in the entrepreneur and innovator communities in the region. Making these specialized resources available on a flexible, non-ownership basis is a documented need identified by WHOI during the launch and operation of the DunkWorks rapid prototyping and additive manufacturing facility, which opened in July 2017 following the support of a $5 million dollar MassTech R&D infrastructure grant.  The $200,000 grant will support the creation of the “D’Works Fund” at WHOI, which will boost access of early-phase marine technology startups to

the maximum diameter (to ensure it remains within the body diameter) or they can influence the design to account for slope of the vehicle’s tail.It is important to take a moment and mention the implications of UUV propulsor manufacture. There is substantial discussion in the press about additive manufacturing (AM) for propellers. While this may be attractive from a financial and deliverability standpoint, we must take care that performance is not compromised by inappropriate surface texture (which can have a huge influence for propulsor of the small size found on most UUVs), fatigue strength failures

pound, 2 man-portable (2 MP) UUV. The underlying technology enabling this family approach, including advanced manufacturing and engineering techniques are key to the Riptide mission of taking UUVs Faster, Further and Deeper.Deeper: Advanced ManufacturingThe micro-UUV was developed using multiple additive manufacturing techniques. This enabled affordable and quick evaluation of numerous design considerations. This rapid manufacturing capability also enabled Riptide to quickly field production vehicles. This approach is not just for engineering models. It is delivering product capable of withstanding the

landscape has changed dramatically in the last decade, and we need to identify ways that these changes can help us learn more about the ocean,” said Mark Abbott, president and director of WHOI and principal investigator for the project. “Not only do we have new capabilities such as additive manufacturing, systems-on-a-chip, and open architectures, but the cultural landscape has evolved as well. Today, innovation routinely occurs in informal ‘maker spaces’ such as innovation garages and even coffee shops. Developing new approaches that take advantage of this landscape, to explore

DNV GL: First Class Guideline for Additive Manufacturing

DNV GL has published the first classification guideline for the use of additive manufacturing (AM) in the maritime and oil amid gas industries. The guideline is designed to help manufacturers and sub-suppliers of materials, parts and components, service suppliers and end users adopting AM technologies, by ensuring that the parts or components created by an AM process and the materials from which they are created have the same level of quality assurance as traditionally manufactured products.    Additive manufacturing is a catch-all term for industrial processes that create three dimensional
