I wonder if instead of using porous metals that something such as cement or ceramics could be substituted on a much larger scale using 3D printing. This would not only make it cost effective for medical professionals but also help reduce the over mining of rare-earth metals.
Can these materials be used for implants and/or replacements? I was not aware of the dangers of infection in joint replacements until my brother had to have both knees redone due to infection. Could porous metals allow for blood flow thereby allowing your own bodies defense mechanisms help ward off infection. Also will the surrounding tissues be able to adhere.
Thomas, you mention that porous metals can be made with a wide variety of metalurgical properties. How strong can they be made, in terms of flexure and elastic properties? Are there some high-strength applications?
Thank you for this informative article on a topic I didn't know much about, Thomas. As someone who did not do so well in chemistry and physics at school, it's fascinating to ponder materials science and learn about all the forms a different metal can take and those various uses.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
