DNV GL launches offshore & marine 3D printing research center at Singapore’s NAMIC

Singapore’s National Additive
Manufacturing Innovation Cluster (NAMIC)  has received a
boost with the launch of a new research center and the
construction of a nanofabrication facility for
multi-disciplinary research.

Global quality assurance and risk management
company DNV GL has
established a Global Additive Manufacturing Centre of
Excellence in the cluster. 

Furthermore, a new nanofabrication facility
under construction at the National
University of Singapore
(NUS) will involve the use of 3D
printing and packaging for the prototyping of new
technologies.

Quality Control at DNV GL’s Centre of
Excellence

According to DNV GL, there has been a
relatively low uptake of 3D printing within the offshore &
marine (O&M) sector owing to the challenges of challenges
in qualification and certification.

To address this, DNV GL aims to provide the
industry with technical standards and guidelines for qualifying
and certifying AM equipment, processes, products, materials and
personnel.

The company has already teamed up with
Australia’s Aurora Labs to develop
a certification framework for 3D printed metal
parts
. Following three years of investigation into
3D printing processes, DNV GL
published its first classification guideline
for additive manufacturing
 in the
maritime, oil and gas industries in November 2017.

The next step is a joint industry project
(JIP) to define clear requirements for 3D printed parts, which
DNV GL is undertaking with key stakeholders to develop
guidelines enabling the safe introduction of additive
manufacturing to O&M industries.

Research & Development at DNV GL’s
Centre of Excellence

The new center will primarily serve as an
incubator and testbed for R&D on 3D printing in O&M. It
is 
supported by the Singapore
Economic Development Board (EDB), and will develop
qualification, certification, and training for 3D
printing.

Research has already begun in collaboration
with Sembcorp Marine, SIMTech and other NAMIC members to
develop and certify laser aided additive manufacturing (LAAM)
technology.

SIMTech’s LAAM technology is currently being
applied to the
fabrication of large-scale structures for new
shipping vessels and component repair 
DNV
GL CEO Remi Eriksen said:

“With our long track record in R&D and strong position in
developing industry technical standards, DNV GL’s Global
Additive Manufacturing Centre of Excellence will play a
catalytic role in the oil & gas, offshore and marine
sector.”

Supporting the investment in Singapore, Singapore EDB’s
assistant Managing Director Lim Kok Kiang added, “DNV GL’s
Global Additive Manufacturing Centre of Excellence (CoE) will
help enhance the manufacturing competitiveness of Singapore’s
marine and offshore engineering industry.”

NUS 3D nanoprinting

NUS’s new nanofabrication facility will
serve as a research platform for collaboration between
multi-disciplinary research groups within the university, as
well as industry partners.

It will host the Hybrid-Integrated Flexible
Electronic Systems (HiFES) programme, which aims to develop
next-generation
hybrid flexible electronics
and has recently secured S $4.9
(US $3.7) million of partnerships with industrial
partners.

Prototyping of new technologies at the
facility will involve precision 3D printing, a combination of
semiconductor and additive-based processes.

Such technologies include nanomaterial-based
reconfigurable interconnects which can introduce artificial
intelligence to flexible electronics, hence enabling machine
learning for new
wearable medical devices
and sensors.

“This world-class facility, when fully
operational, will accelerate the development of disruptive,
cutting-edge applications in hybrid flexible electronics,” said
Professor Aaron Thean, Director of HiFES. “We are keen to
collaborate with more companies to bring novel technologies to
market.”
