NASA is Working on Technology to 3D Print Circuits in Space

A collaboration of engineers from NASA and academia recently tested hybrid printed electronic circuits near the edge of space, also known as the Kármán line. The space-readiness test was demonstrated on the Suborbital Technology Experiment Carrier-9, or (SubTEC-9), sounding rocket mission, which was launched from NASA’s Wallops Flight Facility on April 25 and reached an altitude of approximately 174 kilometers (108 miles), which lasted only a few minutes before the rocket descended to the ground via parachute.
The test consisted of humidity and electronic sensors that were printed on two attached panels along with the payload door, all of which transmitted data to the ground during the brief flight. The mission was deemed a success and holds the potential to help scientists and engineers improve design efficiency for smaller spacecraft.
“The uniqueness of this technology is being able to print a sensor actually where you need it,” said Dr. Margaret Samuels, who is an electronics engineer at NASA’s Goddard Space Flight Center and co-led the experiment with Goddard aerospace engineer, Beth Paquette. “The big benefit is that it’s a space saver. We can print on 3-dimensional surfaces with traces of about 30 microns – half the width of a human hair – or smaller between components. It could provide other benefits for antennas and radio frequency applications.”
The humidity-sensing printing ink was produced at NASA’s Marshall Space Flight Center while the circuits were created at the University of Maryland’s Laboratory for Physical Sciences (LPS), who each coordinated their efforts with Dr. Samuels and Paquette, demonstrating the collaborative effort undertaken for the project.
