The US Navy has conducted Print Sprint II event in San Diego to encourage the use of 3D printing technology at naval shipyards to support fleets.
Naval Sea Systems Command (NAVSEA) Tactical Innovation Implementation Lab (TIIL) organised the event designed to enable navy maintenance providers to work collaboratively to develop new 3D printing solutions and applications.
Print Sprint II comes after the first print sprint was conducted last year at Naval Undersea Warfare Center (NUWC) Division Keyport to gauge the fleet and shipyards’ abilities to create a random part in a short time through additive manufacturing.
Advanced and additive manufacturing service bureau Ivaldi Group has partnered with Wilhelmsen, the largest maritime network in the world. Operating from a new additive manufacturing facility in Singapore, Ivaldi will provide Wilhelmsen with on-demand spare part production for ships and other maritime equipment, potentially servicing upwards of 100 vessels per day.
Speaking with Espen Sivertsen, CEO of Ivaldi Group, 3D Printing Industry learned more about the company’s latest move, and the apparent rise of additive manufacturing in maritime.
3D printing for the maritime and energy industries is the focus of NAMIC’s 5th additive manufacturing summit later this month.
Taking place in Singapore, the Maritime and Energy AM Summit is organized by the country’s National Additive Manufacturing Innovation Cluster (NAMIC), an organization focused on developing a collaborative and innovative ecosystem for additive manufacturing.
At the event 3D printing experts will gather to discuss operationalising AM, how 3D printing is revolutionising the energy industry, the future of advanced manufacturing and other related topics.
I caught up with two of the experts presenting work at the NAMIC AM summit to learn more.
Create It Real, a Danish 3D printing company, has established a pilot project with the Green Ship of the Future consortium to explore printing on board ships and address Intellectual Property (IP) rights.
The project is part of the Green Ship of the Future’s ‘The maritime opportunity space of 3D print’ portfolio, and will specifically look into the streamlining of its supply chain by printing spare parts as and when necessary. It is being financed by the Danish Maritime Fund.
A prototype of the world’s first class approved ship’s propeller has been produced using 3D printing techniques. The 1,350mm diameter propeller – named WAAMpeller – is the result of a cooperative consortium of companies that includes DAMEN Shipyards Group, RAMLAB, Promarin, Autodesk and Bureau Veritas.
The WAAMpeller was fabricated from a Nickel Aluminium Bronze (NAB) alloy at RAMLAB (Rotterdam Additive Manufacturing LAB) in the Port of Rotterdam. The propeller was produced with the Wire Arc Additive Manufacturing (WAAM) method using a Valk welding system and Autodesk software. The triple- blade structure uses a Promarin design that is used on Damen’s Stan Tug 1606. With production complete, the WAAMpeller will be CNC milled at ‘Autodesk’s Advanced Manufacturing Facility in Birmingham, UK’.
This prototype 3D printed propeller represents a steep learning curve of the understanding of material properties. “This is because 3D printed materials are built up layer by layer,” says Kees Custers, Project Engineer in Damen’s R&D department. “As a consequence, they display different physical properties in different directions – a characteristic known as anisotropy. Steel or casted materials, on the other hand, are isotropic – they have the same properties in all directions.”
Additive Manufacturing (AM) is emerging as a preferred term for what most us call 3D printing. Be that as it may, using the deposition of material to build up a part, rather than machining material away — could soon be used to rapidly make large parts for the marine and offshore industry.
LR (Lloyd’s Register) recently held a qualification workshop for Keppel Marine and Offshore and the Singapore Centre for 3D Printing at Nanyang Technological University to map out a safe, sustainable and quality-driven approach to additive manufacturing (AM) of metallic parts intended for rugged environments, such as shipping and offshore oil and gas production.
Qualification is a critical step towards certification and adoption of industrial products made by AM. The workshop focused on a broad range of knowledge and skills required to demonstrate competency in AM and to meet industry quality and safety regulations and standards.
