Stratasys Ltd.
A maker of industrial 3D printers, Stratasys builds the machines that melt plastic filament and lay it down layer by layer to create parts for aerospace, auto, and medical customers. Its story began in a garage in 1988, when founder Scott Crump built a toy frog for his daughter with a hot glue gun loaded with candle wax — a trick that became the Fused Deposition Modeling process. The name comes from "strata," the layers of rock that echo how its printers build objects.
