What You Need to Know
By tuning rheology and cross‑linking chemistry, printers can produce complex, edible architectures that retain shape and texture while enabling novel culinary designs. The process relies on heat‑induced cross‑linking of gelatin or starches to form a polymer network, and shear‑thinning behavior to allow smooth extrusion.
