Researchers at the German Fraunhofer Institute has announced a new technique for the development of 3D printed bone implants. It involves injecting plasma into the implant, thereby promoting cell growth inside and outside the implant which should allow the natural recovery of the bone.
The link between additive manufacturing and medicine has for some time been quite solid, with many applications developing and particularly around bio-printing. Research at the University of Arizona are working on 3D printing to better treat fractures. Through stem cells and 3D technologies scientists involved want to find a more effective way to treat these injuries. This time, German researchers are interested in plasma and additive manufacturing, also with the aim of healing a defective bone.

How to develop 3D printed bone implants?
To create these 3D printed bone implants, a cold plasma jet is injected between each layer of copolymer. Thus forming the structure of the implant which is actually a scaffold that will dissolve over time. This plasma jet makes it possible to place aminopenicillins which are antibiotics with bone diffusion. These then come to mix with the 3D printed structure, forcing the bone cells to find a suitable substrate for their adhesion.
