Looking at it, maybe not as strong as hardened steel but still strong, but won't be long I am sure before they utilize some materials that can rival steel. Also this is not a hoax, just checked it out http://www.hoax-slayer.com/3D-printer-video.shtml
edit, this has got me interested now. It appears they have been able for years to printer layers of metal with lasers to give metal 3d printer. This is expensive, but it is possible and has been done for sometime.
Hadn't seen that before, very impressive. Amazed at the thing the guy was holding up as a demonstration of how it can produce complex items.
