According to university history, “Dr. Caplenor’s efforts led to the creation of an award in his honor in 1984. The Caplenor Faculty Research Award is given to faculty who are engaged in outstanding research while employed at the University, and the winner receives a monetary award and a listing on a permanent plaque displayed in Derryberry Hall. As of 2016, 37 faculty have received the award, which has become the premiere recognition of faculty scholarship and creativity at TTU.”

Selection for the Caplenor Faculty Research Award is a lengthy, rigorous, peer-reviewed process that evaluates a faculty member’s performance as measured by contributions to scholarship and/or creativity that received wide recognition far beyond the University. There are numerous areas for potential contribution, and eight major criteria for nomination, including, to name just a few:

      • Significant recognized peer-reviewed publications, including work with her/his students and collaborators in the field of scholarship or creativity.
      • Presentations such as seminars, lectures, performances, galleries, etc. related to her/his field of scholarship or creativity, including those made by invitation as keynote and/or plenary lectures.
      • Contributions to the profession such as membership on editorial boards, editing journals, special issues, books, etc. and the organization of professional meetings (technical, educational, art exhibitions, etc.)

As just one example of Dr. Ismail Fidan’s dedication to research and creativity at TTU: Over many years his efforts to understand and push the boundaries of what is possible with additive manufacturing is paying dividends now in this moment of crisis. He and his engineering students turned the university makerspace, STEM Center, and department labs into 24/7 3D print shops for COVID-19 protective face shield parts serving state and national needs. 

Under his guidance, the university was also awarded an NSF Advanced Technological Education (ATE) project grant to establish the Additive Manufacturing Coalition and Hub (AM-WATCH). That network is also supporting the university’s efforts around COVID-19. As we shared in the AM News post, the 3D printing COVID-19 effort has produced thousands of face shields (personal protective equipment or PPE) for area first responders and other healthcare professionals.

It is said that Dr. Caplenor symbolized the essence of teaching and research. He was “trained to be a scientist, and he practiced his science with all the intellectual rigor attendant to his profession. But he also had the feeling of a poet and artist,” said former TTU President Arliss Roaden. According to others, “teaching for [Dr. Caplenor] was as natural as his breathing.” 

For those of us who know Dr. Fidan, and for those yet to meet him, we at AM News believe the Caplenor award also recognizes these amazing traits and steadfast dedication in our colleague and friend. Congratulations on your achievement, Dr. Ismail Fidan. 

Here are a few of his other achievements that may inspire your additive manufacturing ambitions:

Due to his innovation-mindedness, he has received the TTU’s Sissom Innovation and Creativity Award three times and the TBR (Tennessee Board of Regents) Lana Doncaster Innovation Award twice. His team is tasked to “innovate in and for additive manufacturing.” Here are a few of his active research projects in Additive Manufacturing:

1) They are working to develop lightweight low-cost sustainable composite printed parts for the automotive and dental industries.

2) They are developing low-cost metal 3D Printed parts for the industry overall.

3) They invented a 3D Printer that can dispense any paste type materials (shown in video above).

4) He and his team developed remote access features and apps to help additive manufacturing labs around the nation.

5) In coordination with Somerset Community College, they created a mobile learning AM platform.

Finally, if you have been seeking to learn more about the cutting edge of additive manufacturing, the TTU Golden Eagle Additively Innovative Lecture Series brings experts in from around the world for a virtual lecture. Dr. Fidan and team have been doing it for the last nine semesters (4.5 years).

Editor’s Corner: 3D Printers Rally To Help Stem COVID-19: Your Help Is Needed

COVID19, aka Coronavirus, is taking its toll on all of us, in a variety of ways. So as I kick off an Editors Corner post here on AM News, I want to use it to update you on positive news all across the Additive Manufacturing and Materials Science communities. 

People are coming together to 3D print, to sew (yes, handmade cloth DIY masks – more on this below, hang on), and explore and test materials for the certified N95 respirators and surgical masks. Plus, I will share a couple of stories from within our community of two educators working tirelessly to 3D print face shield parts for use by those on the front lines. 

At Tennessee Tech University, Dr. Ismail Fidan and team have turned the university makerspace, STEM Center, and department labs into 24/7 3D print shops for COVID-19 protective face shield parts. The University also has a very well-established Additive Manufacturing Coalition and Hub established with an NSF award. Their network is also supporting the university’s efforts.

So far, they have printed 381 masks (as of March 25) that went to the state directly for final assembly and distribution to healthcare professionals. The TTU Department of Manufacturing and Engineering Technology and College of Engineering are running 30-plus 3D printers across the two labs. (Short video with them loading up a box of parts.). The Tennessee Tech team plans to keep printing since there are still more production requests and needs from the state.

University of Louisville runs one of the top Additive Manufacturing programs and has an amazing 3D printing facility for training and workforce development. I spent time there a few years back visiting Ed Tackett who runs it when I happened to be driving across the country (not 3DRV, another time). You can read more about their COVID-19 efforts here: Students Producing 3D Printed Face Shields For Healthcare Professionals. Ed is helping nationwide with people trying to sort out how to print at the highest possible quality and speed.

Normally, I do not cross-link (although there’s nothing wrong with doing it) between my work at Forbes and my National Science Foundation grant project work, but we are in uncharted waters and all the resources we can share with one another, well, it may save a life. If you have a project you are working on related to COVID-19, please get in touch and we will consider adding it here. 

If you are looking for a way to get you or your students involved (great remote, work-from-home, learn-from-home potential), I encourage you to look over the different resources in these Forbes posts — there are many hands-on opportunities: 

As I explained in Forbes, “I had, like many of you, planned to attend the RAPID + TCT event in Anaheim this year. SME, the parent organization that creates the RAPID + TCT event, wisely postponed the event. I have attended several of the RAPID + TCT events and it is always amazing to connect with the community; it is more like a large family reunion, frankly…” But now, thanks to what SME has built, those same people are still coming together to solve one of the world’s greatest challenges.

If you ever wondered if 3D printing is all it claims to be, Coronavirus has helped settle that. 3D printers do all of this and more.”

Let’s close with two final examples of people coming together: 

    • MatterHackers, the largest distributor of desktop digital manufacturing equipment and materials in the USA, created an initiative called the COVID-19 Additive Manufacturing Community Response Hub and it will “connect those in the U.S. who need medical aid (Hospitals and Govt. Agencies) and those who can create it using Digital Manufacturing.” It has been live for three days and hundreds have signed up.
    • The N95 respirator mask is a one-time use item. But healthcare professionals are being asked, all around the world, to keep using the same mask repeatedly. Stanford University has helped answer the question pulling in materials scientists: Can Facial Masks be Disinfected for Re-use? Amy Price, DPhil (Oxon) and Larry Chu, MD on behalf of the Stanford AIM Lab and Learnly COVID-19 Evidence Service Stanford Anesthesia Informatics and Media Lab found that it is possible. See their PDF (linked in the title above) if you are involved in any efforts to help healthcare professionals get access to N95 masks. Hint: 70°C hot air in oven, 30min (not a home oven, to be clear!). Read the PDF with loads of technical details.

Although we are living in challenging times, educators and researchers in the USA and internationally are working incredibly long hours to help and save others. Many of the TEAMM network members are working round the clock to provide much-needed Personal Protective Equipment (PPE) by 3D printing face shields based on an open source design using PETG filament material on a wide range of 3D printers.

Coronavirus may look like it is winning, but based on these stories and dedicated people, there is hope that it will soon be defeated.

Tennessee Tech College of Engineering Team Wins Leighton E. Sissom Innovation and Creativity Award

Tennessee Tech College of Engineering professor, Dr. Ismail Fidan, and his team were awarded the 2020 Leighton E. Sissom Innovation and Creativity Award for their work on the Golden Eagle Additively Innovative Virtual Lecture Series.

AM News has covered these events each time over the past few years and each one provides insights and knowledge from additive manufacturing experts from around the world.

Leading authorities such as Wohlers Associates Inc. (in which Dr. Fidan is one of their associate consultants) state that AM is a breakthrough technology that represents the fourth industrial revolution. It is seen as a transformative advancement because it enables distributed manufacturing and the production of parts on demand while also reducing cost, energy consumption and carbon footprints. Since many do not know about these advances, including students and faculty at other institutions, this semester-long series provides an essential look into what is coming in manufacturing technologies.

The team received a $2500 cash award and an award plaque on Thursday, February 20, 2020 at the College of Engineering Awards Banquet. As the coordinator, Dr. Fidan finds speakers for each event and organizes the flyer and schedule. It should be noted that he has won this award three times (see below), helping to keep innovation in everyone’s mind. Dr. Terry Guo serves as the IT person arranging the online video platform, Zoom, is working properly for all speakers. He also records the speaker presentations so that people can listen later, if desired. Michelle Davis does the introductions and web publishing.

SCC Metal 3D Prints Stainless Steel Parts With Modified $600 Desktop Printers

The additive manufacturing program at Somerset Community College (SCC) recently 3D printed numerous 316L stainless steel metal parts on multiple low cost desktop 3D printers. Metal 3D printing is typically an expensive process requiring metal 3D printers starting in the low six figures. SCC has created an impressive initiative to bring the cost down – way down.

SCC’s process is based on a relatively well-known method known as “Bound Metal Additive Manufacturing” (BMAM). It is also predicted by researchers to be one of the fastest growing methods of additive production over the next several years. The SCC AM program faculty and staff started with several low-cost or fused filament fabrication (FFF) (sometimes known as fused deposition modeling – however, FDM is a trademarked term) 3D printers, typically less than $450 each, then modified them for metal filament extrusion and better build plate adhesion for an additional $150 each (total price tag of $600 per printer). 

Once you print a part on one of the SCC machines, there are still multiple steps to completion. The team started with metal-infused filaments provided by Virtual Foundry and BASF. After accounting for shrinkage and other production issues in the design phase, the parts were 3D printed. SCC worked with sintering experts such as DSH Technologies to debind and sinter the 3D printed parts. Imagine that part is “green” and must be cured, similar to what you might do with a piece of pottery in a kiln (oversimplified, but you get the idea). Below, we link to a few additional resources from Virtual Foundry, BASF, and MatterHackers (a provider of filament).

With the material hardened into something closer to its finished metal state, the team had SCC’s Welding department work on the parts. Senior Welding Professor, Karl Watson, used Gas Tungsten Arc Welding (GTAW), also known as TIG welding. Several fillet and groove welds were applied to the original six pieces and the welding went very well.

Preliminary testing of the parts has also shown hardness values slightly less than stock 316L (stainless steel), but microscopic inspection after finishing work has not shown any inconsistencies thus far. Watson also noted that the heat dissipation during the welding process of the 3D printed stainless was higher than conventional stock stainless.

From this success, SCC’s goal now is to bring this low cost metal 3D printing technology to students, teachers, and the workforce throughout Kentucky. SCC will be providing training workshops across the state in the assembly and set up of low cost metal 3D printers for select educators in Kentucky high schools and community colleges. This work is funded by the National Science Foundation (NSF) and EPSCoR (or Established Program to Stimulate Competitive Research) grants. 

Over the next few months SCC will be dialing in the equipment and their training process for the low cost metal procedures, as well as collecting data on product performance. Eric Wooldridge, Director of SCC’s Additive Manufacturing program, notes that “there is a lot for us to learn about practical welding of 3D printed metal parts, especially parts that have been produced on a desktop 3D printer. Factors of shrinkage, potential zones of weakness, and the best welding practices are still to be determined. These are very exciting but uncharted waters to be sure.” 

SCC will be working with partners across Kentucky, including the University of Louisville and the University of Kentucky, to integrate skills in low cost BMAM into the workforce. SCC will also be working with Tennessee Technological University (TTU) to scale their work across state lines through the support of the Mobile Additive Manufacturing Platform for 21st Century STEM Workforce Enhancement grant from the NSF Advanced Technological Education (ATE) program. 

SCC currently offers a certificate in Additive Manufacturing/3D printing and offers additional training through the college’s Workforce Solutions program. For more information, please visit SCC’s Additive Manufacturing program, or check out their YouTube channel, The Additive Guru, dedicated to 3D printing.
