CVTC To Offer Symposium On Affordable Additive Manufacturing

Mark your calendar: Chippewa Valley Technical College (CVTC) is hosting the virtual 4th Symposium on Affordable Additive Manufacturing on May 14th from 9:00 A.M  to 12:00 PM (Central Time).

Check out the 3rd AM Symposium via CVTC

In a recent workshop at Tennessee Tech University (TTU), Kim Grady presented on how to use a 3D Pen in your classroom. She will conduct a similar workshop from this popular event at Chippewa on the 14th. You can learn more about the previous workshop here: Diving Into Additive Manufacturing With 3D Pen Technology. This workshop promises to help educators get a handle on 3D printing through the use of 3D pen technology. Link and info to register for the current workshop is listed at end of post.

Kim uses the 3Doodler 3D pen in this workshop to demonstrate 3D printing concepts such as layering, joining, geometry and measurement, and adding function to an object. If you are asking: What is a 3D printing pen? — it is a device designed to allow you to make  PLA or ABS plastic 3D objects without a 3D printer. Essentially, the 3Doodler Pen is a handheld extruder.”  –AM News post on previous workshop

This event is a unique opportunity to talk and learn about recent additive manufacturing trends. CVTC is bringing people from the community, industry, national institutes, international organizations, and high schools to get to know each other and open up opportunities for collaboration.

There are recorded videos of previous symposia, developed modules, and more by visiting the Developing Resources for Enhancing Additive Manufacturing (DREAM) websiteIf you are interested in joining this collaborative and interactive event please register here. As part of the National Science Foundation grant, Chippewa is providing a small $200 stipend for high school, middle school, or elementary school teachers who want to attend and participate.

For reference, in November 2020, MatEdU News (our sister publication focused on Materials Education and Materials Science), published a story about the second AM symposium organized by DREAM (NSF Award #1902501).

Wohlers Report 2021 Finds 7.5% Growth in Additive Manufacturing Industry Despite Pandemic

Keeping up with technology trends of any type is no easy feat, but maintaining pace with additive manufacturing would be near impossible without the help of the annual industry-leading report on additive manufacturing (AM) and 3D printing from Wohlers Associates, a TEAMM Coordination Network partner.

In the Wohlers Report 2021, now in its 26th year, is a detailed look at the trends, perspectives, and forecasts that executives and educators find essential for decision making, education, and knowledge acceleration. The report gives readers new to AM a comprehensive understanding of the technology and industry. Veterans of the technology benefit from up-to-date information on growth, recent trends, and important developments worldwide.

Wohlers Report 2021

This year’s 375-page report discusses the impact of COVID-19 on the AM industry. Even with the pandemic, Wohlers Associates found industry expansion of 7.5 percent to nearly $12.8 billion in 2020. Growth was down considerably, compared to average growth of 27.4% over the previous 10 years. 

Most established manufacturers of AM systems saw a decline in equipment sales, but many less-established companies grew in 2020. An increase in business by AM service providers supported industry wide growth. The following chart shows 7.1% growth from independent service providers worldwide, resulting in nearly $5.3 billion of revenue from this group.

Dr. Ismail Fidan, Professor in Manufacturing and Engineering Technology at Tennessee Tech University, is an associate author of Wohlers Report 2021. He focuses on Academic activities and capabilities, and in the section, he highlights the work of over 130 institutions and 15 research institutes, some examples:

  • “Somerset Community College in Kentucky initiated a new AM project called the Rapid Response Additive Manufacturing Initiative (RRAMI). It involved a statewide rapid response network capable of manufacturing critical supplies in the event of future emergencies.” We shared an RRAMI update on LinkedIn related to our AM News social media efforts.
  • “Five Louisiana universities have been awarded a $20 million grant from the National Science Foundation to transform AM research and education in Louisiana.” 
  • “The National Institute of Standards and Technology awarded nearly 4 million to Georgia Tech, the University of Texas at El Paso, Purdue University, and Northeastern University. The grant is to advance the competitive competitiveness of metal AM companies in the U.S.”

In addition to the academic section (and the rest of the regular comprehensive report sections), there are new and expanded features in Wohlers Report 2021:

  • 3D printing of food, medicine, and electronics
  • Pricing of metals and polymers and the hidden costs of AM
  • Methods of AM part inspection
  • Pandemic’s impact on the AM industry
  • Compilation of expert reports from 34 countries
  • Tables of AM systems, software tools, service providers, and third-party materials

Of course, at TEAMM as well as MatEdU, we are particularly interested in the materials science and technician side of the industry and Wohlers Report 2021 has a dedicated section, 40-plus pages, on Materials and Processes. In the materials section, are explanations of the latest material processes, such as, vat photopolymerization, powder bed fusion, material jetting, binder jetting, and directed energy deposition, among others. There are deep dives into polymers, graphene and other nanomaterials, new polymer products as well as metal powders for metal AM. The section also explores various 3rd party material producers and talks about the Senvol public database of AM systems and materials.

If you are looking to understand the industry and its many fast-moving parts, Wohlers Report 2021 is a strong way to start (and finish). Read more about Wohlers Associates here.

Medical Device 3D Printing from Dr. Gaffar Gailani presentation at the TTU Spring Series 2021

Dr. Gaffar will be sharing about opportunities and obstacles for Medical Device AM. With his deep interest in Porous Media, Bone Biomechanics, and Biomaterials, this is sure to be a presentation that captures a wide range of students and faculty as well as entrepreneurs, researchers, and medical professionals. Some of the known challenges in Medical Device AM: 

  • Material Properties (Isotropy vs. anisotropy, Strength) what parameters are required to produce the desired material properties.
  • Motivation to use AM ( Speed, Complexity solver, Cost, Customization,…etc)
  • Optimization of AM for four critical factors
  • Cost calculation for large production.
  • Sterilization (polymers)

On his website and in a brief interview, Dr. Gaffar explained “the United States remains the largest medical device market in the world with a market size of around $110 billion (2016 figures). There are more than 6,500 medical device companies in the U.S., mostly small and medium-sized enterprises (SMEs). Medical device companies are located throughout the country but the states with the highest number of companies include California, Florida, New York, Pennsylvania, Massachusetts, and Michigan.”
