conditions, so needed changing, says Nichol. Instead of more traditional biofouling paints, which leach copper, the project is looking at a type of vinyl, creating a Teflon-like surface.Increasingly AutoNaut’s USVs, including a sensor payload in a fin unit, have been made easier by the use of 3D printing, says Nichol, which not only makes producing parts (mostly with a nylon resin) easier (e.g. moulds don’t have to be made to create some parts and the amount of complex machining is reduced), but also allows for more flexible design, i.e. it’s not constrained by manufacturing methods
The Case for 3D Printing Downhole Tools
Advanced design software supports growth of additive manufacturing applications in the oil and gas industryAdditive manufacturing (AM, aka 3D printing) is beginning to impact product-development strategies in the oil and gas industry just as it already has in many other industries—by shifting the production paradigm in unexpected ways.Particularly in the case of downhole tools, overall tool size is compatible with the range of part dimensions that today’s AM systems are capable of manufacturing. Consider a common piece of equipment on any oil and gas rig: the tricone drill bit. Required to

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 potentials for us. In the design engineering, we no longer have to consider the limits of conventional manufacturing processes everywhere. In this way, we give our customers more freedom in the design of the boats."Orellano added: "At the same time, we can produce
World First: Patrol Vessels Deploy 3D Printers
3D printing technology developed in Darwin will be deployed by the Royal Australian Navy in a world-first trial that will streamline the maintenance of patrol vessels.The Morrison Government will invest $1.5 million in the two-year Supersonic Deposition 3D printer pilot, which will lead to a significant increase of parts availability compared to what the regular supply chain can provide.Minister for Defense Industry, the Hon Melissa Price MP, congratulated the Charles Darwin University’s Advanced Manufacturing Alliance, along with industry partner SPEE3D, for producing the cutting edge and
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 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
