Cornell 3d prints a fully functional speaker (video)

Cornell grad students Apoorva Kiran and Robert MacCurdy have successfully printed a fully functioning audio speaker without the need to install additional components.  Very cool.  This matters because the process involved the integration of multiple materials; plastics for the speaker body, silver ink for the wiring and viscous strontium ferrite for the magnet.  Longer term this could lead to custom printing electronic components that utilize materials with very different properties.

Some commenters are cranking out the old, “I can make a speaker from a paper cup.” thread.  Really?  Think bigger folks. I would love to integrate this kind of work into the classroom.
