An item printed with the Spectrom device.
Full color printing is generally a privilege limited to professional and high-end consumer 3D printers, so the more casual user is likely stuck printing in one or two colors. But Cédric Kovacs-Johnson and Charles Haider, both chemical engineering undergraduates at the University of Wisconsin-Madison, say they have come up with a solution: a sub-$100 device that upgrades desktop 3D printers to print in a full rainbow of colors. They call it Spectrom.
