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 used multi-wavelength texturisation, a technique that utilizes 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 personalized meals.
3D-printed food technology has advanced rapidly in recent years but still struggles to replicate the structure of traditional cooking since most rely on pastes, powders, or gels. Texture, more than appearance, often proves to be the deciding factor in whether consumers accept or reject a new food product.
