Description
Layer‑by‑layer extrusion of hydrocolloid gels and purees that solidify via ionic or thermal gelation.
Technical
The process relies on precise rheological tuning of alginate‑based inks cross‑linked by Ca²⁺ ions and gelatin‑based purees that undergo thermally reversible gelation. Rapid gelation upon extrusion, coupled with a loss modulus (G'') less than half the storage modulus (G'), ensures structural fidelity and prevents filament collapse.
