I was thinking about this type of thing,

But a few years down the line, with the ability to print electronics in the home, or in the library as the case may be.
A designer might be able to sell these designs on a marketplace such as Amazon.com. It might also be the case that a community of designers will post designs for goods for free on the net, but what if there are differences between the finished product of the two designs?
The Amazon purchased stove design is more energy efficient then the stove design available for free through the public domain.
Would it be right for someone to download the Amazon design and then repost it on the net for everyone to use freely, since it is the most energy efficient design available?
