First we thought that 3D printing was just a pipe dream, the stuff of science fiction. Now, we know it to be very real with numerous innovations to follow. This recent report from the National Materials and Manufacturing Board's Division of Engineering and Physical Sciences suggests that 3D printing in space will soon be a reality. Published in July 2014, this 100-page report contains a range of findings on the future of additive manufacturing and its potential in space. The basic idea is that scientists in space could manufacture replacement parts and tools while in-orbit. Visitors are welcome to download and read the entire report, which will be of great interest to scientists, engineers, and others fascinated by the future of technological innovation.
