Metal 3D printing technologies are redefining the realm of possibilities in manufacturing. Among those capable of producing near fully dense metals, their heat-induced sintering or melting process principle results in the characteristics of low energy-efficiency, high-capital and operation costs, and intense hardware and facility requirements. To address these issues, acoustic energy is used to form solid metal and establish metallurgical bonding of metal across interfaces in a voxel-line-layer approach to additively construct three-dimensional fully dense metal parts in ambient conditions at room temperature. In addition, in-process acoustic energy intensity-based microstructure modifications are possible to control and tailor part material properties in real-time. This process provides a path to a set of new metal and composite 3D printing and processing technologies that are energy and cost efficient, highly flexible, and highly scalable in terms of part dimension, build speed, and material complexity.
