The Story Behind the First 3D Printed Wrench in Space [Video]

You may recall that late last year, a breakthrough in manufacturing occurred a few hundred miles above the Earth.

After having sent a 3D printer to the International Space Station and printed its first object, a file for a functional ratchet wrench was emailed to a laptop and printed, marking the first time an object designed on Earth was digitally transmitted into space and manufactured.

Though the news of the first 3D printed wrench in space was big in the media, the behind-the-scenes story wherein an engineer at Made in Space, a startup born at Singularity University Labs, rapidly designed the tool and quickly sought approval from NASA has not been told.

In this clip, Jason Dunn, who is the company's cofounder and Chief Technology Officer, shares the details behind what is soon to become commonplace: digital transmission of designs for offworld manufacturing.
