A research team in the US has achieved a massive breakthrough by 3D-printing a 14-ingredient, three-course meal using a software-controlled technique known as multi-wavelength laser cooking. The study demonstrated a novel way to create texture — a major challenge in 3D-printed cuisine.

The team reportedly used multi-wavelength texturisation, a technique that utilises multiple laser wavelengths to control the texture of a material. The research revealed how lasers can selectively cook printed food during the printing process itself, creating textures that better mimic conventional cooking while opening the door to personalised meals.
