Some companies combine additive manufacturing (AM) and subtractive methods to take advantage of what each process does best. For example, the time needed to build this stainless-steel electronic housing was reduced from 52 weeks for an entirely cast part to 3 weeks by machining the base housing and building up the vertical details directly on the housing using AM.

Eventually, there will be 3D printers that can employ multiple methods of additive/subtractive fabrication along with different materials. Some home-based desktop printers can already use multiple materials (i.e.: ceramics and thermoplastics) and it surely won't be long before multiple printing methods will be incorporated.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
