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.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
