This is a very interesting video I stumbled upon from almost 4 years ago. April 2010 the video is dated, and it was uploaded to Youtube by HP in 2011. The question is, if they foresaw this technology coming, why have they allowed everyone else to jump in the market before they ever did. We still don't have a Hewlett Packard 3D Printer. Whitman, their CEO, says we likely will one in the second half of 2014. Seems like they really missed the boat on this one. Sure, maybe they will come out with an exceptional product and take a huge market share, but if they got started on this a couple years ago, which it appears they intended to, tings would be a lot different.
