Printing houses for the homeless.

The UMake is I find most fascinating. In short it would inspire a younger generation to learn about 3D printing design.

Mosaic Manufacturing's Filament changer could have some very interesting applications using different colored filament's. What about different filament types?

I kid. Really, I'd love a concrete Castle shed in my backyard. http://3dprint.com/12933/3d-printed-castle-complete/

I liked the article about the Kast SLA printer - hopefully it will come to pass, I'd love to see SLA printing at the consumer level.

I think the Ester printer takes the ticket: http://3dprint.com/25342/ester-sls-3d-printer-2500/

http://3dprint.com/23868/cheap-metal-3d-printer-welder/. An opportunity for individuals to be able to do this at an affordable price would allow for some of the most fascinating prototypes ever. This would absolutely advance the home 3D printing movement as far as putting more of the necessary tools in fresh inventor's hands.

Carbon fiber filament. Seems like it would add quite a bit of strength to the print.
