[Discuss] 3D printing patents

[gabriella levine]

That sounds totally spot on, from my understanding "Did Makerbot really
invent this, or are they trying to patent something that the open source
community developed first? ".

 From my understanding, as a start, would be find documentation of such
processes in the public domain, documented by the open source community or
elsewhere ...

But i'm looking forward to hearing what others respond.
