Even if 3D printers have made huge progress, they are not yet ready to be sold at Walmart.
They will need to be much easier to use, and be cheaper, probably below US$300.
I think that they also will need to be connected directly to the Internet and that it should be possible to connect to some website and order to build a specific piece.
We are not there yet.
But, for the technologically savvy, they are not really difficult to use.
Thats exactly what I figured but don't have to much experience so figured I would ask you!
I appreciate you giving a reply. Its a cool post and would love to see more on the 3D printer experience you get after using it a while. Its really cool and the potential is there.
