Apple was granted a patent for a “Method and apparatus for three-dimensional printing of coloured objects” on January 16, 2018. The original filing for this patent was in 2014.
Apple’s Geoff Stahl and Howard Miller cited this need for colour 3D printing systems, “To extend the use of 3D printers to more industries and encourage more household use, it may be desirable to improve the 3D printing technology to make objects that are more versatile and useful to an everyday consumer,” the patent states.
