3d printed dissolvable medical implants
In the human body, magnesium is an essential mineral that actually helps maintain the structural integrity of bones. It also degrades quickly when exposed to oxygen, water, and salts, all of which are abundant in the body.
According to assistant professor at the University of Nebraska-Lincoln, mechanical and materials engineering Michael Sealy, “Instead of having these permanent metal implants, let’s have one that degrades over time. Let’s eliminate this whole idea of a second surgery to have these implants removed. Instead of peening as a surface treatment, where I just hammer my outer surface, I’m going to print so many layers, and then hammer it, and then print a few more layers, and then hammer that,”
