Just how big of an impact 3-D printing will have on the future of space exploration is yet to be seen. But it's starting to seem pretty likely that the spaceships that carry the first humans to Mars, the outer planets, and other star systems, will have at least one 3-D printer aboard. Complete the sentences to explain how 3-D printers could help solve a prob...
