Yes, you just need to attach (via, pin or parent/child) a text object to the 3d object and put the text at the top of the layers (probably a layer that doesn't scale with zoom if you use scale features on other layers) so it shows. If you are thinking of using a 3d object for pixel type text that is more complicated, I am not sure if you can angle the faces to make sure it is always facing the camera.
