We also understand that 3D Systems' main competitor, Stratasys, has applied for a couple of patents related to 3D printed chocolate designs, according to their abstracts:
An additive manufacturing system for printing a chocolate confection, the system comprising a platen, a recirculation loop configured to circulate a flow of a chocolate material, and further configured to maintain a temper of the chocolate material; and a print head the print head being configured to receive at least a portion of the chocolate material from the recirculation loop, and further configured to extrude and deposit the chocolate material onto the platen to print at least a portion of the chocolate confection based on the commands from a controller.
The significant thing is that BOTH of the major 3D printing companies are now actively exploring 3D printed food. This means there's a high probability that we will eventually see 3D food printers of some type at an unknown point in the future.
