Three-dimensional (3D) food printing is an emerging additive manufacturing technology that constructs
edible products layer by layer from digital designs. It promises unprecedented customization of food shape,
texture, and nutritional content, with potential applications ranging from personalized diets to novel culinary
experiences. For example, this technology can create appealing texture foods for patients with swallowing
difficulties and incorporate byproducts (e.g. unshaped produce or insect protein) to reduce waste. Key
benefits include tailored nutrient profiles, creative presentation, on-demand production, and supply chain
flexibility. However, significant challenges remain maintaining nutrient density during processing, ensuring
food safety, consumer acceptance of “printed” foods, and developing appropriate regulatory frameworks.
