Printed Food Becomes a Reality

In a post I wrote after attending the CIDAG conference in Portugal, I commented on a lecture given by Rajendrakumar Anayath about emerging printing technologies. His "3-M" theory in particular piqued my interest, as it outlined the expanded use of printing technologies in manufacturing and medicine as well as media.
Based on a new project by Cornell University, Dr. Anayath can add another "M" to his list: meals. In a series of recent papers, Cornell researchers promote the development of "hydrocolloid printing" or "solid freeform fabrication" (SFF) as a means to create food via printing. Like other forms of digital fabrication, the new process will enable high-precision control of products in a decentralized fashion, as well as the "fabrication of multi-material objects with high geometric complexity."
According to the Cornell researchers, "examples of potential future applications include cakes with complex, embedded 3D letters, such that upon slicing the cake, a message is revealed. Or, even a prime rib with a hidden message. Perhaps an on-demand, customizable menu in which the dish is prepared in any 3D shape that the diner desires: the diner can co-create with the culinary artist in real-time."
Such a proposal is likely to inspire a mixed response—many foodies will be appalled, while some experimental chefs will embrace the new technology. Regardless of the response, it is worth remembering the degree to which current food production is already heavily industrialized. Interestingly, the scientists claim that hydrocolloid printing is the path to mass-customization—a goal that typical industrial molding, extrusion and die-cutting procedures cannot achieve.
