NASA wants to use 3D printing technology to build deep space habitats onsite instead of bringing the materials with them. Towards that end they have announced the 3D Printed Habitat Challenge, in partnership with America Makes, as part of the ongoing Centennial Challenge program.

One can make use of local materials. Most dust will form nice sturdy objects when exposed to directed heat and then allowed to cool. For precision objects one can melt the dust and use components like titanium etc. Which can then make up the object. Energy can be retrieved on site either in the form of heat for melting or in the form of electricity by using solar cells.
The whole point of 3D printing is to use materials on site. And only bring the tool, the 3D printer.

Yup. Another approach would be mixing concrete from locally available materials. [wired.com]
