Amedica (AMDA) has fabricated its first silicon nitride structures with a 3D printing process called robotic deposition, or robocasting.
The products have been scanned with electron microscopy to confirm integrity and validity of the additive manufacturing method, and have demonstrated similar theoretical density and microstructure attributes to traditionally-manufactured silicon nitride fusion devices currently in use.
The method supports AMDA’s strategy to commercialize 3D-printed silicon nitride interbody implants with controllable porosity levels to address specific clinical needs.

“Silicon Nitride is not only very interesting, but also unique in that it behaves actively in the fusion process. That is to say, instead of being a passive support structure, Silicon Nitride, by virtue of its surface features and isoelectric point, attracts early protein adherence to its surface. Protein adherence is essential as a first step in the attraction and subsequent integration of bone cells which will lead to fusion.” —Grant A.
