Hong Kong University of Science and Technology researchers have developed a 3D printing food solution that combines the use of graphene heaters and starch-based printing material with generative AI, all in a single 3D printer. 

Traditional 3D printing food technologies typically require postprocessing steps that lead to imperfect shapes, use unappealing ingredients or even face microbial contamination. Using graphene heaters surrounding the extrusion head, the researchers cook the food as it is printed at a constant, controlled temperature. By heating the material as it is printed, the foods keep their intended quality and shape.
