MassTech Grant Will Connect Ocean Entrepreneurs with WHOI

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

The ability to produce metal parts in a 3D printing process anywhere holds great promise for the maritime sector. The picture shows a 3D-printed aluminum replica of a mooring chain testing bed at the DNV GL lab in Bergen (Image: DNV GL)

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

3D Printed Prototypes for Kraken

Axis Prototypes helped shortened the product development cycle for a marine technology company Kraken Sonar Inc.   3D printing technology or additive manufacturing (AM) gives manufacturers the ability to churn our prototypes of with simple to complex geometries quickly and cost-effectively. Axis Prototypes, a 3d printing company based in Montreal, recently demonstrated these benefits when a marine technology company needed parts under a tight deadline.   Kraken Sonar Inc. is a rapidly growing marine technology company that designs, develops and markets advanced sonar and acoustic velocity

Materials Science and Technology Division Dr. Alberto Piqué is recognized for his contributions to the development of laser-based direct-write (LDW) techniques and their integration with additive manufacturing (AM) processes. Dr. Piqué's work combining LDW with AM is expected to make possible the printing of highly functional 3D parts with integrated electronics, which are difficult and expensive to fabricate with current manufacturing techniques, while reducing the time and cost that takes
