ABERDEEN PROVING GROUND, Md. — Army researchers are working with the Marines to develop 3-D printed drones as materials science, aviation technology and software development merge to deliver new capabilities.
“Several years ago when we were collaborating with our academic partner, Georgia Tech, we had this project where we were focusing on design engineering of small unmanned aircraft systems,” said Eric Spero, a team lead within the laboratory’s Vehicle Technology Directorate.
Spero and his team brought their idea to fruition at the U.S. Army Training and Doctrine Command’s annual event at Fort Benning, Georgia in 2016. The Army Expeditionary Warrior Experiment, or AEWE, puts new technologies in the hands of Soldiers.
This is theme of a new YouTube documentary released by the U.S. Army Research Laboratory (see the links at the end of the article). The video details how researchers first envisioned on-demand printing with a suite of tools that would allow for Soldiers to enter mission parameters and then get a 3-D printed aviation asset within 24 hours.
Researchers then reached out the U.S. Marine Corps and started working with them to provide a software catalog that Marines would use to select and print an unmanned aircraft system for a specific mission.
Additive manufacturing, or 3-D printing, is maturing as a viable means to produce mission-essential parts or equipment at the point of need, said ARL engineer Larry “LJ” R. Holmes Jr.
“We have interacted with Marines who have never touched an unmanned system before to Marines who are experts in unmanned aerial flight,” Holmes said. “Across the board they all seemed to be very interested in the topic of being able to manufacture a tool that they can use that was mission specific and has a turn around.”
Holmes said the Marines expected the turn around to be days or weeks, and the ARL team showed them that the turnaround time can be anywhere from minutes to hours.
Researchers said they plan to streamline their processes based on feedback received from the Marines in order to enable unprecedented situational awareness.
“Things like additive manufacturing with materials, artificial intelligence and machine learning, unmanned systems technologies, these will enable us to bring together the capabilities that will allow the future Soldiers and Marines the decisive edge that they need in the battlefield,” said Elias Rigas, a division chief in ARL’s Vehicle Technology Directorate.
The capability to print something from a spool of plastic that flies off on a military mission is something that captures the imagination, Holmes said.
“I think a lot of folks are interested in additive manufacturing because we’ve seen on sci-fi shows … just walking up to a user interface and saying, ‘cheeseburger,’ and there’s my cheeseburger,” he said. “I think that as additive manufacturing continues to grow and the technologies continue to evolve that we’re going to get to a point eventually where we will be making things in a similar fashion where you will walk up to your user interface and say, ‘unmanned aerial system,’ and it will make it for you.”
The U.S. Army Research Laboratory is part of the U.S. Army Research, Development and Engineering Command, which has the mission to ensure decisive overmatch for unified land operations to empower the Army, the joint warfighter and our nation. RDECOM is a major subordinate command of the U.S. Army Materiel Command.
