Over 500 years later, a new type of printing was invented in the labs of MIT. Emanuel Sachs, professor of mechanical engineering, invented a process known as binder jet printing. In binder jet printing, an inkjet printhead selectively drops a liquid binder material into a powder bed — creating a three-dimensional object layer by layer.
Sachs coined a new name for this process: 3-D printing. “My father was a publisher and my mother was an editor,” explains Sachs. “Growing up, my father would take me to the printing presses where his books were made, which influenced my decision to name the process 3-D printing.”
Sachs’ binder jet printing process was one of several technologies...
