It is remarkable to me that the material in the 3D printer is biocompatible (it doesn't breakdown or cause reactions with the body) and that it is strong enough to serve as a life long skill. The ability to 'print' a 3D replacement upper skull doesn't strike me as that remarkable (any shape can be made).
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
