3D printing stands to be one of the most fascinating inventions but it's about to cause a massive stir, especially as companies rush to protect their designs from piracy. This will be the setting for one of the great battles of the 21st century:
3D Printing “DRM” Aims To Stop Next-Gen Pirates

To give you an idea as to the capabilities of the system at present here's some interesting background information on a 3D printed car...yeah you heard that right
3-D Printed Car Is As Strong As Steel, Half The Weight, And Nearing Production

 

Hey Catalyst...tell me one thing: do you think will be possible to print a living copy of my favourite pornstar?

 

Honestly in the future that very well might be possible, however the moral implications are in somewhat of a grey area.

Actually interestingly this technology stands to give us some amazing possibilities. They will one day be able to print food, organs, etc. What happens when a country is starving yet some greedy corporations don't want their recipes shared for free. The answer is REVOLUTION!

 

We had a hackerspace near Paris. They build a 3D printer. It used silicon as an ink.
They did a DIY dildo workshop.

(and from there the HS declined, it was only stupid, clueless, uninteresting "hacktivist" (as if such thing existed), feminist, polititian-ist, (pseudo)-artist, ... (whatever-ist) coming there, and the cool geeky dudes getting bored, making this place a indie e-harmony without any relation to hacking whatsoever.
