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.
On April 15, 2010, President Barack Obama gave a major speech at the Kennedy Space Center in Florida, announcing that the US would send astronauts to Mars by the mid-2030s. But in order to do so, NASA would first need to ramp up its capabilities through missions directed toward "a series of increasingly demanding targets," i.e. asteroids.
