Space: 3D Printing's Final Frontier

Jan. 10, 2018
The company Made In Space has an out-there, albeit completely accurate, name as its additive machines assist astronauts by making tools aboard the ISS, and could someday have its own factory orbiting Earth.

Sending metal parts up to orbiting satellites and rockets is a slow and expensive process. So why not put the factory in orbit, too?

That idea isn’t as outlandish as it might sound. Made In Space, a Mountain View, California-based company, plans to use 3D printing to manufacture metal parts in space. The technology is already used here on Earth by companies such as General Electric Co. and Siemens AG to build components for everything from jet engines to rockets. Cosmic applications are expected to gain traction as space travel expands. 

The drive to fabricate metal parts in space comes as companies guided by Elon Musk and Jeff Bezos work to make extraterrestrial travel less expensive, fueling an emerging economy to service the industry. According to Made In Space CEO Andrew Rush, the company would function as the “hard hat” construction worker to fashion ready-to-use products from aluminum, steel, and titanium for in-orbit use.

Printing metals parts makes sense because of the challenges in sending “materials and people in space,” Rush said in a telephone interview last week. The goal is to “help people live and work” in orbit.

The National Aeronautics and Space Administration has been among the leaders in 3D printing, partnering with Made In Space to build its first plastic parts in 2014 on the International Space Station.

Interest in space applications is brewing as President Donald Trump recently directed NASA to send American astronauts back to the Moon, and as companies and countries explore ways to mine asteroids for precious and base metals. While it may not significantly shift the outlook for metals demand in the near term, the 3D printing process back on Earth’s soil is gaining traction. It’s changing how products are designed, engineered, and made, and has significant production turnaround time and cost benefits for users, Anthony Forcione, senior equity analyst at Loomis Sayles & Co., said in a blog post late last month.

Made In Space also plans to start a recycling technology system in the next year that will reuse plastic in orbit. The company will later use this as the blueprint for recycling metals, Rush said.
