![]() ![]() So, there have been advances where people look at new materials in space and how to form stronger and more advantageous materials using microgravity as one of the factors.” Hot things don’t rise over colder things, so, a lot of times, that can lead to discoveries when you’re doing material science, especially involved around melting or processing of materials. According to ISS Chief Scientist Kirt Costello, “in space, you don’t have buoyancy-driven convection. The ISS provides a valuable starting point to propel the potential of 3D printing technology for space. The have even taken the first steps toward realizing the requirements for an on-demand, microgravity 3D printing station off Earth. The only permanently occupied microgravity laboratory aboard the ISS has allowed researchers and space crew to carry out hundreds of hours of experiments, proving theories and revealing previously unexplained phenomena. Many of these innovative and viable options have been around since the 1950s, but are only limited to short continuous spans of microgravity that can only last seconds. These included drop towers, suborbital space flights, artificial microgravity simulators, and, particularly, on parabolic flights on Earth that can be tuned to allow for zero gravity or reduced gravity levels like those found on the surface of the Moon or Mars. ![]() Before the National Space Laboratory of the International Space Station (ISS) became a platform for research in orbit, space agencies relied solely on other means. Without the distortion experienced on Earth, investigators can gain insight into the inner workings of physical and biological systems, leading to the advancement of additive manufacturing (AM) technology in orbit.įor years, researchers have performed studies in microgravity. Microgravity offers an ideal environment to explore the basics of many types of scientific research and can hold the key to unlocking the full potential of 3D printing. That’s because observing phenomena and processes in microgravity conditions can help prepare the field for deep-space human explorations and provide knowledge to improve the quality of life on Earth. ![]() The extraordinary advantages of a weightless laboratory have fascinated scientists for decades. ![]()
