3D printing of food is turning from pipe dream into commercial reality, as nutrition supplements firm Nourish3d is about to prove.

While the idea of 3D printed food might still seem in the realms of a sci-fi novel, the technology s very much present and already being deployed by, in particular, baking industry professionals for cake or pastry decoration.
At present, the technology is limited and relatively expensive, with the lowest cost of a 3D printer being around $1,000 (£784). Using extrusion, current 3D printers can only handle paste or puree ingredients, such as chocolate, cream or batter. However, the technology is beginning to gain traction, with users understanding how it can help to meet changing demands from consumers.
