NASA is investigating how it could make tools and replacement parts by printing them in space using 3D printers. See NASA's vision for 3D printing in space.

The first 3D printer in space has popped out its first creation -- a replacement part for the first 3D printer in space. The 3D printer, delivered to the International Space Station two months ago ...

Instead, they can use a newly arrived 3D printer to fabricate the tools and materials they need. "The 3D printer that we're going to fly on space station will actually be the first-ever 3D printer ...

There are no hardware stores in space (yet). So what fancy new tools will the next generation of space hackers use? The first 3D printer to make plastic parts arrived at the ISS a decade ago. This ...

Already, 3D printing in space is underway. On the International Space Station, astronauts use 3D printers to make tools and spare parts, such as ratchet wrenches, clamps and brackets.

Aboard the International Space Station, NASA is testing 3D printers that recycle old plastic to make new tools, a practice that may be a critical part of future moon missions.

The future of space travel requires new technologies and additive manufacturing, more commonly known as 3D printing, may hold the key.

Users on Earth can pay to use AMF, a 3D printer specially designed to operate in a microgravity environment, to print products on the space station.

Never thought 3D printers would be on the International Space Station? As of June of 2014, they will be, and this video shows how they'll work.
