Great article about the filtration properties of porous metals.  In addition to being effective filters I also get the impression that this technology is cost-effective.

 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.

 It's amazing to see how many prosthetic knees and hips fail, tool_maker. A family friend had to have her artificial hip replaced due to surface chemicals leaching into the bloodstream.

  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.

High strength

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?

I second that--thanks, Thomas. And I think AnandY has a good point about inspiration from nature.

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.

@Thomas, thanks for the psot. I think inspiration for porous metal have come from nature. Nature's porous materials like bone, coral which are lightweight and strong.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
