Stratasys, a 3D printer marker focused on manufacturing, on Monday launched a color system that can use multiple materials. The name of the printer, Objet500 Connex3 Color Multi-material 3D Printer, doesn’t quite roll off the tongue, but could have implications for design, engineering and manufacturing. While 3D printing is capturing the imagination of consumers to some degree, the real action in the sector revolves around manufacturing and the supply chain.
