In 1987, the first paper on "Three-Dimensional Printing" included this illustration. The paper described both the colored and uncolored versions of "cut-on-the-stack" lamination. It was issued after the 1987 CIP which resulted in US #5,015,312 and was widely distributed from April 1987 to April 1991.
"Three-Dimensional Printing - A Tool for Solid Modeling" was presented and officially "published" at the April 1991 Conference of the National Computer Graphics Association . It seemed that most attendees were convinced that computer graphics would very soon eliminate the use of physical models for "visualization."

It has even been reported that Ford Motor Company has resumed cooperation with art schools in order to train the next generation of "clay modelers" for the visualization of automobiles.
