The US Department of Energy Office of Energy Efficiency and Renewable Energy has awarded The University of Maine Advanced Structures and Composites Center (UMaine Composites Center) with US$2.8mn for the development of a rapid and low in cost additive manufacturing (3D Printing) solution to fabricate large, segmented wind blade molds.

“The University of Maine remains a leader in additive manufacturing and wind energy technology, and this funding will harness researchers’ expertise in both areas. We are thrilled that the Department of Energy continues to invest in UMaine’s cutting-edge research and prioritizes the advancement of our state’s clean energy economy and the creation of good-paying jobs,” commented Sens. Susan Collins and Angus King.

In addition to the funding provided for the project, UMaine Composites Center will also collaborate on a US$4mn award to Oak Ridge National Laboratory (ORNL) to apply robotic deposition of continuous reinforcing fibers in wind blades.

“Building on a decade plus of research excellence in nanocellulose, composites and wind blade testing, University of Maine researchers and students will apply this knowledge to additive manufacturing, transforming large wind blade development and accelerating innovation in this growing market. I congratulate all of the UMaine researchers and students for continuing to advance transformational research to help grow Maine’s clean energy economy. We thank the Department of Energy for its partnership and our Congressional delegation for their continued interest and incredible support for this world-class research and development underway right here in Maine at our university,” added University of Maine President Joan Ferrini-Mundy

Currently innovations for large wind blade technology are costly and time intensive, due to tooling and large blades costing upward of US$10mn and a time to market of 16 to 20 months. 

“Very large wind blade molds will be printed on the world’s largest polymer 3D printer located at the UMaine Composites Center using recyclable bio-based materials reinforced with wood. By combining cutting-edge 3D printing manufacturing with bio-based feedstocks, our team estimates that new blade development costs can be reduced by 25% to 50% and accelerated by at least 6 months. Molds produced using these materials can be ground up and reused in other molds, making them a more sustainable solution,” stated Habib Dagher, executive director of the Advanced Structures and Composites Center.

Gartner: Leaders Lack Skilled Smart Manufacturing Workers

57% of manufacturing leaders feel that their organisations lack the skilled workers needed to support smart manufacturing digitalisation

With organisations rapidly adopting industry 4.0 capabilities to increase productivity, efficiency, transparency, and quality as well as reduce cost, manufacturers “are under pressure to bring their workforce into the 21st century,” says Gartner.

While more connected factory workers are leveraging digital tools and data management techniques to improve decision accuracy, increase knowledge and lessen variability, 57% of manufacturing leaders feel that their organisations lack the skilled workers needed to support their smart manufacturing digitalisation plans.

“Our survey revealed that manufacturers are currently going through a difficult phase in their digitisation journey toward smart manufacturing,” said Simon Jacobson, Vice President analyst, Gartner Supply Chain practice.

“They accept that changing from a break-fix mentality and culture to a data-driven workforce is a must. However, intuition, efficiency and engagement cannot be sacrificed. New workers might be tech-savvy but lack access to best practices and know-how — and tenured workers might have the knowledge, but not the digital skills. A truly connected factory worker in a smart manufacturing environment needs both.”

Change Management

Surveying 439 respondents from North America, Western Europe and APAC, Gartner found that “organisational complexity, integration and process reengineering are the most prevalent challenges for executing smart manufacturing initiatives.” Combined they represent “the largest change management obstacle [for manufacturers],” adds Gartner.

“It’s interesting to see that leadership commitment is frequently cited as not being a challenge. Across all respondents, 83% agree that their leadership understands and accepts the need to invest in smart manufacturing. However, it does not reflect whether or not the majority of leaders understand the magnitude of change in front of them – regarding technology, as well as talent,” added Jacobson.

Technology and People

While the value and opportunities smart manufacturing can provide an organisation is being recognised, introducing technology alone isn’t enough. Gartner emphasises the importance of evolving factory workers alongside the technology, ensuring that they are on board in order for the change to be successful.

“The most immediate action is for organisations to realize that this is more than digitisation. It requires synchronising activities for capability building, capability enablement and empowering people. Taking a ‘how to improve a day in the life’ approach will increase engagement, continuous learning and ultimately foster a pull-based approach that will attract tenured workers. They are the best points of contact to identify the best starting points for automation and the required data and digital tools for better decision-making,” said Jacobson.

Long term, “it is important to establish a data-driven culture in manufacturing operations that is rooted in governance and training - without stifling employee creativity and ingenuity,” concluded Gartner.
