Nice. Now, where's my pool-table sized, laser-printed scale replica of the Roman Forum, circa Julius Caesar's time?

I saw on the news that they printed a playable vinyl record. I thought that was the most impressive use of the printer.
Wow that's amazing I googled it - and it's unreal. I had no idea they could do this! Its one of those TED talks (a little long but worth it I thought). http://www.ted.com/talks/anthony_atala_printing_a_human_kidney.html
Yeah, pretty cool, but as the video says it's still a few years away. However, I found an article yesterday that brings it a little closer: http://www.scientificamerican.com/a...ood-vessel-creation-kidney-liver-large-organs
