3D printing the Eta Carinae Star System.

Posted on Updated on

According to NASA’s  Scientists,” Eta Carinae is a bright star system consisting of two stars surrounded by gas. Scientists have been using computer simulations to study star systems.  Computer simulations can be difficult to study on a 2D screen.  Therefore scientists used the 3d printer to create a 3D model of the star system. The 3D model makes it easier to study the star system.¨

NASA and Made In Space, Inc. have partnered to install a 3D printer in the International Space Station.   This is the first tool to be 3D printed in space that was designed on earth and emailed to the International Space Station.  The wrench took 4 hours to create on the space station.

According to NASA’s, chief strategy officer of Made in Space, “These first 3D prints will be brought down to Earth for examination where they’ll be compared to identical objects manufactured on the ground we’ll use them to characterize the effects of long-term microgravity on our 3D-printing process so that we can model and predict the performance of objects that we manufacture in space in the future.”
