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.
In his keynote address at the RAPID 2015 conference last week, Made In Space CTO Jason Dunn gave an update on how far his company and co-development partner NASA have come in their quest to bring 3D printing to the space station -- and beyond.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
