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

the status quo and never challenged,” said Wyss Institute Founding Director Donald Ingber, M.D., Ph.D., who is also the Judah Folkman Professor of Vascular Biology at HMS and the Vascular Biology Program at Boston Children’s Hospital, as well as Professor of Bioengineering at SEAS. “3D printing and soft robotics technologies are now allowing the processes of design and iteration to happen on-site rather than in the lab, making it faster, easier, and cheaper to create solutions to existing problems.”Additional authors of the paper include Kaitlyn Becker and Mortiz Graule from the

(shown in Figure 3, on page 44), the initial design was determined to well exceed the threshold depth rating, which was then increased to 300 meters for the standard vehicle while maintaining an adequate factor of safety.Riptide utilized the latest methods of rapid manufacturing heavily relying on 3D printing or additive manufacturing in its early production deliveries. Riptide has recently procured injection resin molds for all 3D printed parts for the micro-UUV under a manufacturing grant from Massachusetts, but maintain the ability to 3D print any component for design flexibility.

The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the U.S. Navy in Memphis since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air- or water-borne transportation systems. (Photo: U.S. Navy)

test parameters,” said Foster.The test objects are suspended in a 10 x 10 by 43 ft. long chamber. The chamber can be drained and opened to gain access to the test object, which can be changed to test difference shapes and configurations. “We can create different control surfaces through 3D printing,” said Brown.Right now the LCC is being used to characterize the performance of the propulsor for the Columbia-class ballistic missile submarine, the replacement for the Ohio-class submarines. “We built a scale model of the entire submarine and propulsor to measure everything from

innovative start-ups taking advantage of the latest trends in miniaturization and the relatively low-cost entry into the market. “If I were trying to do this five years ago, it would have been a lot more difficult, and that is probably why more start-ups are entering our market now. There is 3D printing, satellite technology, battery technology and miniaturization on these elements that means in the short-term future it’s going to be much easier to collect ocean data and to mass produce affordable underwater robots to complete all sorts of complex tasks. It’ll be very disruptive to

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 objects by adding layers of material. It includes such technologies as 3D Printing, Rapid Prototyping (RP), Direct Digital Manufacturing (DDM), layered manufacturing and additive fabrication.   “We have been investigating the potential of 3D printing for the maritime and oil & gas sectors since 2014,” said Marit Norheim, Vice President, Material Specialist

well as support for the MOOS-IvP robot control engine. Future releases are planned to include support for ROS (the Robot Operating System) and streamlined user interfaces.   In addition to embracing current software development trends the micro-UUV has been developed using a large quantity of 3D printing. This has enabled affordable and quick evaluation of numerous design considerations. This rapid manufacturing capability has also enabled Riptide to quickly field production vehicles. This approach is not just for engineering models. It is delivering product capable of withstanding the pressures

Naval Staff, added, “Unmanned Warrior clearly demonstrated the Royal Navy’s ambition to lead and win through technological innovation. Unmanned maritime systems will change how we operate, but they’re just the start. Our pursuit of new technologies and ideas – from big data to 3D-printing – will ensure we remain one of the most capable and successful navies in the world.”   Delivering Maritime Capability When the Unmanned Warrior program was completed in line with the U.K. government’s Strategic Defense and Security Review direction on innovation and defense

World's First Fabrication of Subsea Well Part Using LiDAR Data and 3D Printing

and 3D at Depth, a global provider of advanced subsea LiDAR systems and solutions, announce the world's first application of subsea LiDAR data used to 3D Print an accurate 1:1 physical model of a damaged well part.    The ability to use accurate spatial data in subsea part fabrication with 3D printing, introduces a wide range of possibilities to reduce costs across intervention planning and Life of Field programs.    The subsea part fabrication was part of a larger project conducted in early 2016, using 3D at Depth's subsea LiDAR SL 2 technology and point cloud software.
