Researchers at Cornell University are using augmented reality (AR) to advance three-dimensional (3D) printing and 3D modeling technologies, enabling designers to design in physical space while a robotic arm rapidly prints the work.

The new in-situ fabrication technique was used in the team's Robotic Modeling Assistant (RoMA) system, in which a designer wears an AR headset with hand controllers.

"The combination of AR and robot allows the designer to use the just-printed part to design their next features," says Cornell's Huaishu Peng. He notes the new interactive method lets the robot and the designer work together, with the robot knowing to print in the back of the object if the designer is working in the front, and automatically re-compute the changes being made in real time.

In the future, the Cornell researchers believe this type of robotic arm can serve as an intelligent design assistant.
