The ExOne Company announced it has reached a commercial license agreement with the U.S. Department of Energy’s Oak Ridge National Laboratory to 3D print parts in aluminum-infiltrated boron carbide (B4C). Researchers at ORNL developed the patent-pending method of 3D printing aluminum-infiltrated B4C on an ExOne M-Flex, a 3D printer that uses binder jetting technology to 3D print objects in metals, ceramics and other powder materials. In 2019, ExOne executed an R&D license for the manufacturing process. Now, that license has been expanded to commercial use so that ExOne can begin printing aluminum-infiltrated B4C collimators, shielding equipment, and other components used in neutron scattering research.
