3D food printing uses protein, starch, fat, and vegetable bioinks to build complex food structures layer by layer.
Origin: MIT Media Lab (USA), Japan, Korea (2015–present) — North America, East Asia
See full technique reference →Protein inks undergo ionic cross‑linking (e.g., Ca²⁺) to form a solid network, starch inks gelatinize upon heating to 60–70 °C and set upon cooling, and fat inks rely on stable emulsions maintained below 5 °C. Precise rheology and temperature control are essential to preserve shape fidelity during extrusion.
Primary Reaction
Ionic cross‑linking of protein networks, starch gelatinization, emulsion stabilization
