Abstract: A method for printing a three-dimensional crystalline structure such as a chocolate layer wherein, after printing, the material has a desired crystal structure. An embodiment can include printing a liquid first layer of material with a printer onto a second layer of material having a crystal structure. Subsequently, the printed liquid first layer is processed to solidify the first layer. During the processing of the printed liquid first layer, the second layer functions as a crystal seed layer through physical contact with the printed liquid first layer and the second layer crystallizes with the crystal structure.
