MatEdU Builds Collaborative Internship Model Around Materials Science Skills

AM News regularly seeks stories on projects and programs that help additive manufacturing and materials technicians stay competitive in a rapidly changing job market. The need for well-qualified technicians is a challenge for many industries. As a National Science Foundation grant, The National Resource Center for Materials Technology Education (MatEdU) is hard at work to bring materials technology education and resources to the nation. 

MatEdU is a TEAMM Collaboration member and earlier this year published a case study on a successful internship collaboration project between academia and industry. This project provides a range of real-life learning experiences that benefit the student and gives educational institutions ways to provide skilled technicians needed by industry. 

Development of Collaborative Internship Model and Partnership with Boeing

Here are some of the issues identified by MatEdU as pressing challenges in the field of materials science technology:

  • The current workforce needs advanced skills to develop new products and infuse legacy products with advanced manufacturing practices using cutting edge materials and technologies and advanced industrial processes;
  • The current aging workforce is retiring at a time when the number of technical jobs is increasing;
  • New workers must be attracted and must develop skills to flexibly meet continuously evolving manufacturing industry demand.

In order to start working on these challenges, MatEdU, Edmonds Community College, and The Boeing Company together proactively developed a Collaborative Internship Model as a strategy for addressing the need for skilled technicians in the aerospace workforce. Research by The Boeing Company looked at the following kinds of needs assessment questions:

 

  • How many engineers, scientists, and technicians do we need in our foreseeable future?
  • What skills and knowledge will they need?
  • How do we attract the next generation technical workforce that possesses a much broader multi-disciplinary and systems engineering perspective?
  • How should we enhance our technical educational system?
  • How do we attract and retain a student population reflecting the demographics of our diverse society?

 

 

 

After identifying core challenges from the research findings, a pilot program was designed and developed in collaboration with academic (MatEdU and Edmonds Community College, Lynnwood, WA; Department of Materials Science and Engineering, University of Washington, Seattle, WA) and industrial partners (The Boeing Company, and Boeing’s Materials and Process Technologies division, Seattle, WA) and implemented with a two-year community college in the professional technical division. 

Known as the Educational Experiential Learning Exposure Internship (EELEI) , the program was targeted at closing the technician workforce gap. With the increasing use of advanced composite materials in the design, testing, and repair of products like the 787 Dreamliner, Boeing has a constant need for qualified and experienced materials science technicians to replace a specific segment of its aging technical workforce. The Collaborative Internship Model supports and complements the Materials Science Technology (MST) program, a 2-year Associate of Applied Science-Transfer degree focused on materials science technology at Edmonds Community College.

Since 2008 approximately 74 students have successfully completed the internship program. About 45 interns have been hired full time. About 10 interns have gone on to a 4 -year institution – five of those are still with Boeing. Prior to 2015 most of the interns worked part time by having their summer internships extended until graduation.

Multi-Institutional Collaboration in Additive Manufacturing

Collaboration is a terrific way to learn and during the 2018 Fall semester, five students from two community colleges and one university worked together to share their design and additive manufacturing (AM) facilities and capabilities. Three students were from Tennessee Tech University, one from Sinclair Community College, and one from Somerset Community College.

NSF TTU Collaboration Bottle Opener Before After

The goal was to join forces to allow teams to leverage skills gained in different courses, improve design competencies, and have an opportunity to apply them in the lab. Before that, however, design files were evaluated and modifications suggested, when appropriate. One of the student teams studied technical drafting in one community college’s design course, while the other two institutions opened the doors of their AM labs so that students can take that design knowledge straight to a 3D printer.

Project Evaluation: Students’ Perspectives

When asked about the part of the project that they enjoyed the most, the students stated the following:

      • 3D printing in different machines and materials
      • I helped and recommended design changes to optimize the part, especially the bottle opener side. I recommended to reinforce the area with more stress concentration
      • The redevelopment of the opener was a great aspect because it showed me how a real product would work through the design process and how to change and fix problems
      • Testing to see what worked best
      • The design phase

The students indicated having learned invaluable lessons from the bottle cap opener project, to include the following:

      • Design is not about looks;
      • It is about functionality;
      • How to efficiently optimize the part with the help of CAD software;
      • The redevelopment stage of designing and how the first design will always change;
      • Iterative designs are great for improvement of the end product, and;
      • Ergonomic design techniques.

Using a simple bottle cap opener, students sought to see if they could improve it with design and 3D printing skills (image above of the before and after designs). In addition to the design and printing revisions that helped students achieve a functional finished product, students improved design skills, plus they gained other unique soft skills that will help them as they graduate and head into the workforce or further studies. According to the four professors involved (see list below), from an evaluative standpoint, overall, the project was a success. Both the faculty and students were satisfied with the process and product.

Wohlers Associates Offers New DfAM Course For Managers

Wohlers Associates and America Makes are partnering to offer a one-day design for additive manufacturing (DfAM) course for managers and executives. Following the success of previous DfAM courses conducted for engineers and designers on four continents, this course is the company’s first foray into educating management on wide ranging issues associated with DfAM.

The course is open to the public, with members of America Makes enjoying discounted pricing.

“AM is an inherently multidisciplinary technology,” said Ray Huff, associate engineer and DfAM instructor at Wohlers Associates. “Just as product development teams must rethink the way a product is designed, company management must also gain an appreciation for the new methods, software tools, and considerations that AM presents. Unlocking the vast potential of AM requires a broad understanding of both the opportunities and challenges.”

According to Wohlers Report 2019, the largest application of AM in 2018 is the production of end-use parts, as shown in the following chart. Jigs, fixtures, and other forms of tooling—a combined 18.5%—represent an important range of applications that can save companies a tremendous amount of time and money. End-use parts and tooling rely heavily on designing in a way that optimizes for the AM process. Managers and executives considering the adoption of AM for production applications will gain an advantage over others if they attend this course.

Course presentations, discussions, and hands-on exercises cover the economics of AM, consolidating many parts into one, and topology optimization, which is letting mathematics decide where to place material to optimize the strength-to-weight ratio. The course also covers lattice/mesh structures, the importance of DfAM rules and guidelines, and distortion modeling and simulation. The course includes considerations for metal, polymer, and composite materials, the creation of custom products, and reducing the need for expensive support material. Those attending the course will receive Wohlers Report 2019 at no additional cost. Details on the course are available at this web page.

Mark Your Calendars: Golden Eagle Additively Innovative Lecture Series Fall 2019

The golden eagle is one of the fastest and most agile raptors in North America. As the mascot for Tennessee Tech University (TTU), it is completely appropriate and logical that a majestic bird of prey with a metal material in its name would be used by Dr. Ismail Fidan as he continues to build the Golden Eagle Additively Innovative Lecture Series for Fall 2019.

With a wide range of additive manufacturing subject matter experts, this workshop series features AM advances, industry innovations, design thinking and materials usage.

This is the eighth semester of lectures organized by TTU and Dr. Fidan. Here are the upcoming virtual lectures that you will want to add to your calendar this fall. The lectures are scheduled for 11—11:30 a.m. CST and can be joined via Zoom at that time.

    • Thursday, Sept. 26: Generative Design Will Change the Future of Manufacturing with Shashi Jain, Strategic Innovation Manager at Intel Corporation, Portland, Oregon.
    • Thursday, Oct. 17: Sustaining Accessibility for Kids’ Creativity with Additive Manufacturing with Pisut Koomsap, Ph.D., Associate Professor, Department of Industrial and Manufacturing Engineering, Asian Institute of Technology, Pathumthani, Thailand.
    • Thursday, Oct. 31: Design and Additive Manufacturing of Porous Titanium Scaffolds for Optimum Cell Viability in Bone Tissue Engineering with Bingbing Li, Ph.D., Assistant Professor, Department of Manufacturing Systems Engineering and Management, California State University, Northridge, California.
    • Thursday, Nov. 7: FDM based Metal Additive Manufacturing with Haijun Gong, Ph.D., Assistant Professor, Department of Manufacturing Engineering, Georgia Southern University, Statesboro, Georgia.

If you want to know how TTU fully embraced their “Golden Eagle” mascot, you can read the full story here. The Golden Eagle is a terrific reflection of the engineering department ethos that its faculty, staff, and students would be driven to show manufacturing and materials excellence in their work — with block tin, gold, and many other materials and methods.

On February 14, 1925, the nickname ‘Golden Eagles’ was officially adopted. It wasn’t until 27 years later that a tangible mascot found its way to the campus. Several Tech students braved a driving night rainstorm to pilfer a huge block-tin eagle statue from the charred ruins of a resort hotel in Monteagle. They painted the creature – with a wingspan of over six feet – a glistening gold, and suspended it from the rafters for public inspection at the following day’s basketball game in Memorial Gym.”

Golden Eagle Additively Innovative Virtual Lecture Series is partially funded by the NSF Award 1601587, “AM-WATCH: Additive Manufacturing-Workforce Advancement Training Coalition and Hub”. The archive of past Golden Eagle Additively Innovative Virtual Lectures is found here.
