  • Patent number: 11412755
    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 and a plurality of non-random cavities. 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. In some embodiments, confections may be formed from high-quality chocolate, where the confection has a reduced caloric content with acceptable mouthfeel. In other embodiments, a confection may have a previously unrealized mouthfeel and taste.
