Update: will not be 3d printed, look below for the link!
Here is a video on why it is not going to work:
From 3d Systems page:
As part of this agreement, 3D Systems plans to substantially expand its multi-material printing capabilities including conductive and functional materials. The company also plans to combine additive and subtractive manufacturing methods, and deliver an integrated high-speed production platform. Pending successful completion of the development phase, 3D Systems is expected to manufacture 3D-printed Ara smartphone enclosures and modules as Motorola’s exclusive fulfillment partner.
Motorola and 3D Systems, the inventors of the cell phone and 3D printer, respectively, have previously partnered on the MAKEwithMOTO tour, a series of make-a-thons at the nation’s top engineering and design schools aimed at exploiting the power of open, hackable smartphone hardware and 3D printing to begin seeding an open hardware ecosystem.

Here is the first prototype and hands.on with Ara smartphone:
Looks like the Ara will not be 3d printed. It is a setback for the entire 3d printing technology fied:
