Researchers at MIT have developed a rapid 3D-printing technique that uses liquid metal to allow for extremely fast prints. The process can manufacture large aluminum components in minutes, whereas many pre-existing techniques would take hours to finish the same build. The technology has already been used to create table legs, chair frames and related furniture parts.
It’s called liquid metal printing (LMP) and involves directing molten aluminum along a predefined path into a bed of tiny glass beads. These beads quickly harden into a 3D structure. Researchers say the new process is at least ten times faster than comparable metal manufacturing techniques.
However, there is one major caveat. This process sacrifices resolution for speed and scale. This is why the researchers have used it to create low-resolution items like chair legs and not, say, intricate parts with complex geometries. MIT researchers say this trade-off still makes the technology useful for creating “components of larger structures
