Materiom Is Serving As Nature’s Recipe Book For STEM Educators

If you are an educator, a maker, a biohacker, or a curious student, who is often trying to come up with recipes for #natural #materials to test out in your classroom, workshop, or lab, this Materiom site is for you. Their Materials Library is filled with “recipes” for materials you might throw away as compost-worthy, but that can be used in a variety of student projects.

Here are a few recipes you will find and the image above gives some ideas as to what you will find on the site. 

  • -Eggshell biocomposite
  • -Sawdust / agar
  • -Chitosan 12% – Stiff behaviour
  • -Sodium Bicarbonate / Cornstarch
  • -Green tea
  • -Kombucha fabric
  • -Agar bioplastic (heated)
  • -Coffee grounds (used)

According to their home page, “Materiom provides open data on how to make materials that nourish local economies and ecologies. We support companies, cities, and communities in creating and selecting materials sourced from locally abundant biomass that are part of a regenerative circular economy.”

Users can customize and finely tune their materials recipes for their long list of over 50 different  materials (or variations of some materials). Search their Materials Database here.

If you are anything like the team at TTU that invented the paste-based 3D printer known as the TechBot, (patent-pending) then you might be able to use one of these novel, DIY pastes found on Materiom. Both these recipes were created by Marita Sauerwein and E.L.Doubrovski. Check out the Mussel shell | alginate MS01 recipe as well as the similar Mussel shell – sucrose composite. The recipes are on a Creative Commons CC BY-SA 4.0 license, but be warned, they are rated 5 out of 5-stars for difficulty.

Golden Eagle Additively Innovative Lecture Series Spring 2020

The College of Engineering at Tennessee Tech is organizing its ninth Golden Eagle Additively Innovative Lecture Series for Spring 2020. Under Dr. Ismail Fidan’s leadership, he and his team coordinate with top-notch speakers from around the world. A combination of experts from academia and industry are recruited to share cutting edge knowledge with university students and anyone who simply has a desire to keep learning about additive manufacturing. 

The web-based presentations are shared via the free Zoom platform. On the dates listed, simply visit Zoom URL ( tntech.zoom.us/j/432789883 ) at 11am Central Standard Time and you can listen in to the 30-minute lecture/discussion. Mark your calendars for one or all of these excellent presentations.

Tennessee Tech Sends Two Students To M-STEM 2019 Workshop

Earlier this year, Tennessee Tech (TTU) created and built an innovative mobile 3D printer. After a number of improvements since the launch, the team of Ankit Gupta and Seymur Hasanov, both graduate research assistants and PhD candidates, represented the TechBot project for TTU. 

After his keynote, Ames Lab scientist, Dr. Iver Anderson (and other M-STEM presenters) spent the afternoon reviewing student entries in the Poster competition and interviewing each student or team. If you are interested in a brief overview of his Keynote presentation, you can read about it here and watch a short video compilation of his main points: M-STEM 2019 Keynote: Meet Climate Change Challenges with Clean Energy Innovations.

Editor’s Note: Due to the large and public area where the posters were displayed, it has quite a bit of background noise, however we tried to diminish that as much as possible (which still did not make much of an impact). 

Ankit Gupta and Seymur Hasanov explain how the new TechBot can print with different materials and how they tested each material for its strength and other traits. The TechBot tests currently included paste-based materials, such as cake frosting, floor paint, and concrete. It is also offered as a do-it-yourself (DIY) kit (assembly required). The project is funded through NSF Award 1601587, Additive Manufacturing Workforce Advancement Training Coalition and Hub (AM-WATCH) under the leadership of Dr. Ismail Fidan (Leader) and Dr. Michael Allen (Co-Leader).

Update: We forgot to share an important video from earlier in 2019 – it is embedded below, but if you cannot see it in-post, then click the TechBot launch video. It is a must-watch. 

M-STEM 2019 Keynote: Meet Climate Change Challenges with Clean Energy Innovations

With M-STEM 2019 focused on Earth, Energy, and the Environment, Ames Lab scientist, Dr. Iver Anderson’s keynote described how climate change is challenging the scientific community to drive clean energy innovations. 

At the Ames Lab, a U.S. Department of Energy research facility operated by Iowa State University, Dr. Anderson leads out in how materials can renew energy. The future of cheaper, cleaner, and more efficient means of creating energy were areas that Dr. Anderson shared in his keynote at M-STEM. 

As you will see in the short video clip of his talk, he explains how energy and energy generation is changing in the USA and worldwide. His goal included giving participants  new data; statistics and insights into renewable energy and the urgency to do more about it. He starts with looking at global electricity generation distribution, that is, how coal, natural gas, solar, and wind, among other methods are in use today. 

In his keynote, he tackles some of the thorny issues around greenhouse gas emissions by energy type and that Lignite (soft and dirty coal) and Coal are the biggest contributors. These greenhouse contributors are the obvious targets of alternative energy sources, such as wind, solar, and water. The cost of power generation is going down and the price of natural gas is so low and so much more efficient, that coal is going down in use in the U.S. and around the world. 

He highlights that it is important to remember that although Wind and Solar are coming up, Natural Gas and Coal are base load — add electrical capacity all the time, 24-hours a day, and energy from those kinds of power plants are still needed. Wind and solar are not the base load provider, so there has to be a mix. In addition, the average cost of energy in North America shows how solar has decreased in cost to be very close to wind generated power and natural gas costs. 

He closes this video section with who is moving the fastest to convert coal plants to renewable sources and China is the winner there. They have a huge dam as a hydroelectric source and are building large scale wind farms. In Europe, Germany has banned nuclear power and is building offshore power; they are the second biggest producer of wind power behind the United Kingdom. But the one renewable power source that wins every prediction: Solar Photovoltaic (PV). 

 

Dr. Craig Brice And Adam Savage Prove 3D Printed Titanium Marvel Ironman Suit Is Tough Enough

During his Tuesday M-STEM keynote, Dr. Craig Brice revealed various exciting and challenging engineering lessons for both him and his students.  Adam Savage’s plan — this suit will fly and will go through some ballistics testing — as you will see in the video (in some cases we are showing you a video of a video).  Marvel Studios sent Brice the design files, but they needed to be completely rebuilt in order to actually work.

Adam Savage and team informed Dr. Brice that, as a test,  they planned to fire a 9mm pistol at the titanium metal 3D printed suit, at fairly close range. Dr. Brice then called up a colleague who helped him determine exactly how thick the plates would need to be to withstand the 9mm caliber. Listen carefully and look at the slides he is pointing to and you will see that the suit handles more than he expected, maybe even Ultron level. 

You can jump back to our Day One post where he shares a few quick details while showing M-STEM attendees the 3D printing lab with the EOS metal 3D printer that was used in this project (although EOS ultimately decided to help print many iterations of the project as changes were made to various parts).
