Multi‑material 3‑D food printing extrudes protein, starch, and fat inks at controlled temperatures to preserve functional properties and achieve structural stability through cross‑linking and rapid curing.
Origin: Japanese, Chinese, American (2015–2020) — Japan, China, USA
See full technique reference →Protein inks are extruded at 20–35 °C to maintain native structure, starch inks at 30–45 °C and cross‑linked with 1–3 % calcium chloride, while fat inks are extruded at 10–15 °C. Rapid curing (30–60 s) and precise print speeds (5–10 mm/s) ensure shape fidelity and mechanical stability.
Primary Reaction
