Wohlers Report 2019 Academic Activities Chapter By Dr. Ismail Fidan

Dr. Ismail Fidan from Tennessee Tech University is in the news often. The engineering department professor is actively serving the AM community; from his students at TTU to the larger group of professionals and analysts who read the annual Wohlers Report. Dr. Fidan contributes a thorough chapter each year on the activities and capabilities within academia.

He notes there is a strong and growing demand for workers trained in additive manufacturing. There are many colleges and universities adding certificates and degrees centered on AM processes. Many of these institutions are conducting research and forming industry-level partnerships within AM.

In the report, he states, “Professional survey results and interviews suggest that skill sets developed using AM technologies are vital for graduating students who are entering the workforce. In response to the growing opportunities in the AM job market, interest among students in AM-related design and manufacturing courses has increased significantly.”

“AM provides students with the opportunity to take their designs to the next level by allowing them to get involved in the fabrication stage. In response to this need, the number  of newly established AM- based makerspaces and innovation institutes around the world has grown significantly.”

As a TEAMM Network member, Dr. Fidan is committed to technician education. In approximately 15 pages, in the Academic activities and capabilities chapter, he chronicles the many academic projects and initiatives taking place around the world. It is a veritable Who’s Who in additive manufacturing.

According to his Wohlers Report 2019 chapter, there are 125 academic institutions and 14 research institutes listed along with short summaries of the areas of focus, including the individuals to contact. The 125 academic institutions are located in the following regions:

      • 28 in Asia/Pacific
      • 34 in Europe
      • 57 in North America
      • 6 in Africa and South America

Dr. Fidan has served as a member of the Wohlers Report team for the last three years. In his role, he collects and reports on the worldwide academic AM practices, trends, and innovations. Currently, he is one of the associate authors of the report. TEAMM continues to look to Dr. Ismail Fidan for his thought leadership within AM and education.

Tennessee Tech Launches New Mobile Multitasking 3D Printer

Tennessee Tech University (TTU) announced today that it is launching TechBot, a mobile, multitasking 3D Printer designed, developed and fabricated by TTU faculty and students. TTU has applied for a provisional U.S. Patent on the 3D printer.

Although there are many 3D printers on the market today, the TechBot differs in its mobility. Most printers today demand a rigid frame structure. This new printer is not limited to a traditional work envelope as are other conventional 3D printers –  the user can define and set up their own work surface to print almost any type of material from the paste-based extruder.

This is another key difference with the TechBot – it does not use traditional 3D printer materials, such as, filament, powder, pellets, or resin that are commonly used in several other additive manufacturing processes. It has a paste-based method, using a syringe, to dispense any paste type material on any X and Y direction. It can do 200mm in height on the Z axis.

The team has found a number of uses and applications for this Mobile printer:

      • Using the TechBot mobile multitasking platform to develop a mobile tape applicator for multi-purpose gyms. This will result in a quick and precise method to convert a multi-purpose gym floor from a basketball court to a volleyball court.
      • The TechBot platform can also be used to incorporate a fast drying paint extruder to paint team logos onto arena floors. During Sports tournaments, the TechBot could paint both team logos onto an arena floor within minutes. This paint can be removed with the appropriate dissolver.
      • Another application for the TechBot platform is in the construction industry to extrude grout between tile gaps.

Other applications are being explored, across a wide range of areas, such as, 3D food printing (think cakes, pies, desserts) to circuit boards. The team has also looked into the printing of concrete structures with the TechBot. 

The TechBot is designed to incorporate 4 omnidirectional wheels at the corners which greatly improves the print accuracy. The extrusion head is incorporated within the frame of the TechBot, this makes it possible for one z-axis to be capable of printing multiple materials using different extrusion methods. The TechBot is also offered as a do-it-yourself (DIY) kit (assembly required).

TechBot is funded through NSF Award 1601587, Additive Manufacturing Workforce Advancement Training Coalition and Hub (AM-WATCH). Research Team Members are:

The TechBot team also received technical support from Ed Tackett (University of Louisville), Amy Elliott (Oak Ridge National Laboratory), Tom Singer (Sinclair Community College), and Mel Cossette (Edmonds Community College).

TEAMM Network Member Dr. Ismail Fidan Profiled In News

At TEAMM and AM News, we like to celebrate when our members receive recognition for their accomplishments. Recently, Dr. Ismail Fidan from Tennessee Tech University (TTU) was profiled in the regional newspaper, the Cookeville Herald-Citizen, for being a researcher focused on how additive manufacturing is making an impact on everyday life.

Dr. Ismail Fidan profiled in Cookeville Herald-Citizen

The article highlighted that, “Fidan Is working towards securing his 10th grant funded by the National Science Foundation, which would bring the amount of grants funded for his research to more than $4.6 million during his time at TTU, all related to additive manufacturing. He has been working in the field for nearly 15 years.”

The profile also mentions how he has worked “with other institutions to establish an additive manufacturing laboratory framework, including a smartphone app that helps institutions work together, collaborate and share resources for 3D printing projects.” This includes the AM lab at Edmonds Community College.

AM News, of course, has written about the importance of Dr. Fidan’s Golden Eagle Additively Innovative Virtual Lecture Series (SEE NOTE for last two events for Spring 2019 below), a web-based presentation series given by national and international experts in additive manufacturing. So far, the series has trained more than 500 people in the diverse applications of additive manufactur­ing. In addition to these web-based lectures, Fidan organizes an annual workshop on additive manufacturing to address gaps in the current knowledge base of technicians through the development of curriculum and educational materials and sup­port to more than 30 community college and high school instructors per year.

There is still time to join in on the final two lectures (click that above link for more info OR you can click this Zoom link in any web browser at 11am U.S. Central Standard Time):

Demand Grows For 3D Printing Technician Education At Undergraduate And Graduate Levels

There is a worldwide emphasis and need to increase skills in additive manufacturing. One only need look around at the number of educational and for-profit ventures building out detailed degree programs and curricula to see it.

In the news last month, Wichita State University announced a new 3D Printing Technician Graduate Certificate program at WSU. It is exciting to see this higher level program in addition to the many we see in motion and developing at community college and 4-year college programs.

We talked to TEAMM Collaboration Network member, Dr. Ismail Fidan, who is a professor of Engineering at Tennessee Tech and associate author of the Wohlers Report, updating the annual academic R&D and education trends in AM around the world. Dr. Fidan shared that “There is no fully dedicated AM degree program at the public community college and university level within the ABET accreditation records. But there are several manufacturing degree programs. I personally believe that there will be some coming in the future.”

According to Dr. Fidan, there are several Master and certification programs on AM around the world. Some of the more recent ones are the Metal AM MS Program which will be offered by Cranfield University, UK. SME also came up with an AM certification program for the Community College level. (Links below.)

AM News profiled the Somerset Community College Offers 3D Printing Technician Certificate in mid-2018. Thanks to Tennessee Tech University (TTU) College of Engineering with its Golden Eagle Additively Innovative Lecture Series, an online webinar event that reaches people around the world. We learned about the Somerset certificate program through the webinar.

Wohlers Associates (publisher of the above-mentioned report), also a TEAMM member, created a unique Design for Additive Manufacturing (DfAM) course that has since been requested by other companies and organizations. Terry Wohlers writes about the Impact of DfAM here.

Additive manufacturing is growing and its future looks bright. If you know of other degree programs and courses aimed at helping technicians, engineers, and other manufacturing specialists increase their skills, please get in touch so we can add them to our growing list and potential upcoming posts.

Community Colleges Are Innovating and Incubating New Ideas And Companies

As the world changes, education moves to change with it. A new book on the power of community colleges to serve as new business incubators and innovation centers is about to hit the marketplace. Community Colleges as Incubators of Innovation: Unleashing Entrepreneurial Opportunities for Communities and Students by editors Rebecca Corbin, Ed.D. and Ron Thomas, Ph.D. offer a collection of expert contributors’ thoughts.

With the support of the National Association for Community College Entrepreneurship (NACCE), they “start from the premise that community colleges are uniquely positioned to lead entrepreneurial initiatives through both internally-generated curriculum design and through collaboration with the local entrepreneurial community to build bridges between the classroom to the community which in turn can offer models of implementation and constitute a network or support system for students. Community colleges can become incubators of innovation, a magnet for talent, and provide the impetus for development strategies that their communities have not begun to realize.”

At AM News, we hear about a lot of projects helping students to complete their degrees or certificates and get into the workforce. Colleges within the Technician Education in Additive Manufacturing & Materials (TEAMM) project actively work to advance technician education, particularly in materials science (and the adaption of ASTM skills standards).

TEAMM Network member schools are actively building makerspaces, innovation hubs, and entrepreneur research experiences, just to name a few of the concepts. In fact, we have profiled a number of them from Tennessee Technological University (TTU), University of Louisville (its Rapid Prototyping Center), and The Facility makerspace at Edmonds Community College.

TTU is consistently active in developing unique projects to engage students in an entrepreneurial way. Dr. Ismail Fidan is the Principal Investigator (PI) or Co-PI on numerous NSF Grant awards to keep these college-age innovators on their toes. Check out two of the TTU entrepreneurial initiatives coming out of the College of Engineering:

Community colleges continue to adapt to the ever-changing job market. These entrepreneurial incubators and related coursework, as well as micro-credentials in the form of certificates, are providing students with more new startup ideas (and mentoring for those ventures) as well as work opportunities. If you wonder if today’s college programs are preparing students for the future of work and business, the answer appears to be a resounding yes.
