Rapid tooling technology opens up route to low-cost cast metal components


A Georgia Tech (Atlanta, GA) research team has developed a novel technology that enables ceramic molds to be fabricated directly from CAD data and it could change how industry designs and casts complex, costly metal parts according to its developer, Suman Das, a professor at the George W. Woodruff School of Mechanical Engineering.

Das explains: "Today most precision metal castings are designed using CAD, but the next step—creating the ceramic mold with which the part is cast [using investment casting]—currently involves a sequence of six major operations requiring expensive precision-machined dies and hundreds of tooling pieces."
