Advanced Technological Education (ATE) Celebrates 25 Years

The 25th Anniversary of the National Science Foundation’s (NSF) Advanced Technological Education (ATE) program is a reason to celebrate in STEM (Science, Technology, Engineering, and Mathematics) education circles.

For 25 years, the ATE program has invested in and grown technician education opportunities around the nation to prepare a “STEM-capable workforce.” That includes many different types of classes, modules, and certificate programs, in addition to traditional two-year degree programs that are already a strong part of the community college system.

Here are just a few of the statistics:

  • $1.1 Billion is the total NSF ATE Investment to date
  • 715 organizations have received ATE funding
  • 61 ATE Centers and 1,294 Projects have been funded by ATE
  • In FY2017, $66 Million Went To 300-plus Active Grants

All of these efforts focus on technician education, across the USA, to help students graduate, but also to help high tech employers in the workforce. Many of the programs highlighted in the annual report called “Impacts” are part of the TEAMM network, which is the sponsor of AM News. Throughout this coming 2018-2019 academic year, we are going to highlight the network member programs as found in Impacts and through direct interviews, when possible.

ATE Impacts explores and reports on seven major categories:

  1. Advanced Manufacturing Technologies
  2. Agricultural and Environmental Technologies
  3. Bio and Chemical Technologies
  4. Engineering Technologies
  5. General Advanced Technological Education
  6. Information and Security Technologies
  7. Micro and Nanotechnologies

Today we will look at one featured Project and one ATE Center:

Featured Project: AM-WATCH (Additive Manufacturing – Workforce Advancement Training Coalition and Hub)

According to Impacts:  “AM-WATCH provides opportunities for secondary school and two-year college students and educators to learn additive manufacturing technologies. More than 700 students were impacted positively by the project from fall 2017 to spring 2018.” It plans to add more locations to its existing 25 learning sites in Tennessee and Washington.

In a recent Train-the-Trainer Studio, educators were taught how to build 3-D printers to help them prepare technicians for additive manufacturing careers.  Results found that educators:

  • 77% increased their ability to design a system, component, or process
  • 80% increased their technical and nontechnical communication skills
  • Educators report AM-WATCH’s Train-the-Trainer Studios improved their performance on specific ABET accreditation skill sets

ATE Center: MatEdU – National Resource Center for Materials Technology Education

MatEdU is well-known as a materials technology education repository for educators and students. It appears in the number one spot for search engine results for a wide variety of materials science terms and directs students and educators to useful resources.

Students can learn about a variety of career pathways in materials science. Educators can find content that helps them plan a variety of lessons, entire courses as well as core competencies documents outlining required depth of proficiency for a range of related subjects, such as, manufacturing technology, corrosion technician, nanotechnologist, and more. Instructional resources include course designs, materials videos, and recommended book lists, to name just a few items from the Instructional Resources page.

Each year, MatEdU organizes a Materials in STEM conference (two days) known as M-STEM that attracts educators and students around the country. This year is hosted by the University of Alabama – Birmingham on November 5 and 6.

The Facility Is Creating A Sustainable Makerspace Model To Aid Student Job Potential

According to the Credit reporting site WalletHub, Washington State’s economy ranked No. 1 in the nation, driven by strong gross domestic product growth, exports, and the percentage of high-tech jobs. Those high tech jobs include careers in STEM (Science, Technology, Engineering, and Math).  Of course, that would mean that advanced science fields, such as materials science and additive manufacturing rank high, as well.

Student education and workforce training programs contribute to that job growth and overall career opportunities. So, it comes as no surprise that Edmonds Community College enthusiastically supported the idea of creating a makerspace for students and the community. The makerspace is called The Facility and is housed in Monroe Hall, which is already a well-equipped materials science lab.

The Facility is different than many college makerspaces, however, because it is a hybrid model that allows student use and also invites the community, residents who are not students, to come and use the space at low cost. As you will hear in this short video, David Voetmann, Makerspace Program Manager of The Facility, explains how the process works for joining and participating in the space.

What is a Makerspace?

Briefly, a makerspace is like a woodshop or metal shop or automotive class that many area residents would remember. A place, as Voetmann says, to share tools and innovation. Except instead of only power saws or welders or impact wrenches, you would have 3D printers, laser cutters, or 5-axis CNC machines – computer-controlled milling machines that cut on multiple angles. In addition, Monroe Hall is unique in that it is home to equipment that can make something out of carbon fiber (materials science) via vacuum bagging and an autoclave, not your usual makerspace gear.

You can check out other TEAMM videos or look at the Materials Education channel on YouTube.

Resources for Starting Your Own Makerspace

Since two of the most popular machines in a makerspace are 3D printers and laser cutters (or laser engravers), it is logical that companies that provide those tools would have good resources.

3D printer manufacturer, Ultimaker, has a number of posts, books, and resources for school teachers, administrators, librarians (public and school), who might be interested to build a makerspace. One is called the Makerspace Bookshelf and the other helpful post is Fablab, makerspace, or hackerspace? –that highlights how to decide which one is right for your situation.

LulzBot, one of the dominant 3D printer brands in education, has a case study on the Loveland CreatorSpace: Come for the Tools, Stay for the People.

FormLabs, a resin-based 3D printer company, published Incentives and Ingredients for Building a Makerspacethat is instructive.

If you have been contemplating a laser cutter, and a variety of other equipment, Epilog Laser, based in Colorado, offers a number of posts and a downloadable guide for lasers in education to help you determine what you need as well as steps to take to get your space up and running. This post (though it presents a slight bias given what they sell) Why Will a Laser be the Most Popular Tool in My Makerspace? presents four reasons why a laser will be a hit in your makerspace, hackerspace, or fab lab.

Laura Fleming, an educator and media specialist, has written two excellent, best-selling books (also mentioned on the Ultimaker site). You can find both of them on her website: Worlds of Making. Both of them are about creating a makerspace in your school. They are also available on Amazon. She offers a steady stream of ideas and maker tips on her Twitter account – @LFlemingEDU.

The study mentioned earlier in the post: WalletHub study: 2018’s Best & Worst State Economies. This article on the Edmonds Community College website gives additional details of how the school intends to use the makerspace: The Facility and the Rapid Proto Lab at Edmonds Community College.

Somerset Community College Offers 3D Printing Technician Certificate

In February, Tennessee Tech University (TTU) College of Engineering announced its Golden Eagle Additively Innovative Lecture Series, an online webinar event that reaches people around the world. The third lecture focuses on a relatively new 3D printing technician certificate offered at Somerset Community College (SCC).

The formal title of the third lecture in the series is “AM Research and Applications for Real World Production and Impact” with Eric N. Wooldridge, PE, RA, Professor of Additive Manufacturing, Workforce Development, and Pre-Engineering at SCC, Kentucky.

All across the USA, industry is increasingly interested in training for 3D printing. Not many schools offer a degree in 3D printing (yet), two or four year, and fewer have specialized certificates for those interested in the field. From automotive to aerospace, biomedical to home improvement to Hollywood special effects, additive manufacturing training is forecasted for growth.

Somerset Community College (SCC) is the first institution of higher education in Kentucky to offer a statewide certificate in additive manufacturing. In fact, it is one of the few in the nation and comes up early in a Google search for a related search, such as, “3D printing technician certificate schools colleges.”

Professor Wooldridge explains:

The move to go “certificate” is because industry is asking for students with skills as fast as possible whether referring to additive or welding, it wants technicians that can produce and can produce now. Additive manufacturing is still hardly known and relatively misunderstood, so we created the one-year certificate to allow various Somerset degree programs to add these skills into their Associates degree path and help to integrate additive within the company along with their primary job.  We wanted to create an additive “foothold” situation within our state so that existing manufacturers will have someone on the inside that can help them transition faster to the technology instead of lagging behind the curve of their competitors.

We also created a demonstration process to entice industry leaders to consider additive within their own operations.  We call it the “Netflix deal” where a company can come to us to try an idea with 3D printing – we’ll will take out all the risk of equipment cost, and the need for expertise, etc., produce a demonstration example for them relative to their operations (sort of like a Netflix trial that hooks you into the service).

After the experience, most will immediately want to do this on their own – so they send us employees for training – in some cases just one employee, in others we have trained 7 people for 16 hours of one-on-one training, or more accurately, re-training. Local employers have been very interested, supportive, and tapping into this new educational technology opportunity.  Over time, the goal is for graduating students to get hired at these same types of companies. 

But in either approach we are steadily making progress in integrating practical 3D printing applications into our region and our entire state.  So that we will have a workforce well suited for implementing cutting edge manufacturing innovations, as well as creating an ideal economic investment opportunity for tier one companies.

You can find a host of resources on the SCC web page here on the “Research and Grant Materials” folder (marked with the red arrow via the link/image above). Professor Wooldridge has a variety of terrific case studies, videos, materials testing projects and photos, as well as some program brochures. All of this is in a shared cloud storage drive.

Here are some of the courses required for the 3D Printing Technician-Level 1 Certificate (Total: 16 to 18 credit hours):

  • DPT 100 Introduction to 3D Printing Technology
  • DPT 102 3D Printing Technology Fundamentals
  • BAS 160 Introduction to Business
  • BAS 170 Entrepreneurship
  • DPT 150 Introduction to Engineering Mechanics for 3D Printing
  • DPT 280 Special Projects for 3D Printing, Level 1

University of Louisville Offers Additive Manufacturing Safety Training

The University of Louisville is an active member of the TEAMM Network and recently announced they have added an Additive Manufacturing (AM) Safety Workshop, conducted through their Rapid Prototyping Center, run by Ed Tackett, Director of Educational Programs in AM.

The new program is called the “AM Metals Safety Training Workshop” and is an advanced training for AM professionals. It is a one-day session (8 contact hours) held at the Additive Manufacturing Competency Center (AMCC).

The AMCC is a fully equipped learning laboratory that includes the latest AM technologies, machining, metrology and powder handling systems. Metals additive manufacturing requires an increased environmental health and safety effort. This new workshop is designed to help new users identify hazards, reference appropriate regulations and develop a mitigation strategy. Learn more about the AM Metals Safety workshop.

This workshop is designed to benefit supervisors, lead workers, managers, employers, and anyone responsible for the safety and health of employees and labs. The workshop covers various types of standard machinery, machine safeguards, and related regulations and procedures for metals additive manufacturing.

In an Additive Manufacturing magazine post by Christina M. Fuges, there is a good interview on safety with Ed Tackett. He shares a story about companies not realizing they have major safety risks with AM:

There’s recognition of the need to be safe, but the real question is what does it take? AMCC seeks to ensure students know the risks specific to AM and how to mitigate those risks. Believe it or not, companies are not being safe. We had a group come in for training, and after the initial day’s safety lecture, they immediately called their company to shut down the AM lab. They had no idea some of these dangers existed.

The AM Metals Safety Training Workshop was created to help reduce these risks and get new and experienced technicians up to speed on the safety needs with advanced metals 3D printing.  TEAMM is a strong proponent for materials/workplace safety and believes this class is a trendsetter in AM lab standards.  As new materials are developed and 3D printers are increasingly capable of utilizing multiple materials, it is imperative that technicians understand these materials’ properties both individually and as they are combined during the AM process. Learn more about the AM Metals Safety workshop.
