ISS Multi-Material Fabrication Laboratory Using Ultrasonic Additive Manufacturing Technology

The goal of this program is to demonstrate the use of Ultrasonic Additive Manufacturing (UAM) solid state metal 3D printing to provide in-space, on-demand manufacturing capabilities to support the unique challenges of long-duration human spaceflight. Previous and ongoing work in NASA SBIR programs has demonstrated the ability to 3D print quality metal parts using UAM. The goal of this Phase I program is to demonstrate the feasibility to reduce the size and power consumption of current UAM machine technology to 3D print aerospace grade aluminums for In-Space manufacturing. In fact, for the UAM process, operation in a micro-gravity environment contributes to power reduction goals expressed in recent NASA documents (NASA, 2016).
