The body, seats, and major components were 3D printed in a process called direct digital manufacturing (DDM) but not every part of the car was made this way. Propulsion is still from a traditional motor, in this case an electric motor from a Renault Twizy. Other mechanical bits including wires, suspension, and the battery were also not 3D printed.
Well, this is a little less amazing. I suppose it's still a milestone for 3D printing, but an actual, fully 3D printed car this most certainly is not.
