Toward the end of June, 3D printing companies Stratasys and MakerBot confirmed what TechCrunch had already uncovered, the former would be acquiring the latter for $403 million (or 4.7 million shares) in exchange for 100 percent of MakerBot’s outstanding capital stock. Stratasys has long been a dominant force in 3D printing, long before we were buying 3D printers for our homes. The company specializes in factory-level printing and prototype printing for designers and manufacturers.
