Popular 3D Printing & STEM Education News (September 17th – September 21st)

This was definitely a busy week in the 3D printing world! The first consumer based 3D printing retail store opened its doors on a busy Manhattan street and great strides were made on the CAD software side of the industry. We hope this momentum keeps up!

An Education Transformation

“Innovate or perish” rings true for every industry, including education.

Online education is transforming the way students are being educated. Within the past few years there has been a change in which students are obtaining their college degrees — “out” with the traditional lecture hall format and “in” with the new online class. The amount of students gravitating towards online classes is growing and mainly because of cost. It is no surprise that online classes are easier for students on a budget and have greater schedule flexibility.

Stanford, MIT and Harvard are just a few colleges now offering free online classes to students all over the world. Currently these free classes are relaying information and just  teaching the basics, you are not actually working towards a Harvard degree; Who is to say that this won’t become the new norm within the next 5 years, and that students across the globe will be earning their degrees completely online. While online degrees pose a challenge for education content and message delivery, it is even more challenging to bridge the gap between theories and real-world application.

As Kevin Craig, Professor of Mechanical Engineering, Marquette University points out in his blog post Engineering Education Upheaval, “I have heard it said that it is easier to move a cemetery than it is to change an engineering curriculum. Engineering schools for whom that is true might soon be buried in those cemeteries.” Engineering schools, and STEM subjects in general, have a hard time changing and often become trapped by “this is how it has always been done” ways of thinking. Now is the time for these schools to break free of past methodology and embrace a new innovative approach to learning and teaching.

Engineering content must be rebundled and integrated with a balance between theory and industry best-practice. That information then becomes knowledge that is not a commodity. It is this knowledge that stimulates students and transforms them into critical-thinking problem solvers resulting in a real competitive advantage in this global economy. -Kevin Craig

In Kevin Craig’s blog post, you can see an interesting diagram he has composed that offers a complete restructuring of content delivery to students. In this diagram, on-site work plays a much greater role than learning theories does. While theories are important, in today’s workplace hands on education is what really counts.

When it comes down to it, education is changing and people need to let go of their notions of what should be and embrace what can be. Just because it is new, doesn’t mean it is wrong.

Top 5 Robotics Trends of 2011

We found this Design News article to be very informative and wanted to make sure we shared it with our followers. There have been some amazing innovations in 2011 and we cannot wait to see what 2012 will bring!

The five most important robotics trends of 2011 enable volume manufacturing and aim at further integration of robotics with machine vision and automated systems. Some of the trends outlined discuss very targeted applications, from bomb sniffing to baggage handling, but the developments in each are relevant to other, sometimes very different, types of applications. These developments concern both the design of robots themselves and the systems in which they work.

The Top 5 Materials Trends of 2011

Design News released an article this week on the top five material trends of 2011. There were some interesting observations presented in the article that we wanted to share with our followers.

“The five most important materials trends of this past year enable volume manufacturing. They are concerned mostly with new alternative materials or processes. Volume may start out small, but the material or processes will likely spur high growth. The five areas the article looked at were additive manufacturing (AM), plastics, composites, metals, and recycling.

Several trends concern automotive manufacturing. Here, new materials and processes must not only meet regulations and cost objectives, but also must fit smoothly and easily into highly automated manufacturing processes without compromising them or slowing them down.”

  1. Additive manufacturing: The most important development was the big burst of new materials.
  2. Plastics: Aside from these medical-grade plastics, the most significant plastics breakthrough this year was bioplastics.
  3. Automotive composites: Demand is growing for several different types, primarily carbon and glass fiber.
  4. Steel and recycling: The steel industry also contends that newer lightweight, high-strength steel can give composites a run for their money when it comes to strength and emissions.
  5. Composites and recycling: Boeing’s celebrated launch of its composite-heavy 787 Dreamliner is one indication that carbon-fiber composites could be plentiful in landfills when they eventually wear out. The company’s decision to help fund research on how to recycle those materials may presage or spark further work in this area, which could also affect the growing amount of plastics used in automotive and medical applications.

Robotics Testing Takes on Hockey Sticks

Design News posted an interesting article about the strides that robotics testing is taking in the world of ice hockey. Golf clubs have routinely been tested to evaluate the technical claims of the manufacturers using robotics, but these same concepts had not been applied to hockey sticks…until now.

“John McPhee, a mechanical engineering professor in the Systems Design Engineering Department at the University of Waterloo and an avid hockey player, saw an opportunity to apply similar robotics testing to hockey stick designs, helping manufacturers develop high-performance sticks with lasting durability.”
