“Cellulose as an edible ingredient for 3D Printing” – Presented by Sonia Holland, University of Nottingham

Cellulose is the most abundant polymer in nature, providing structure to plant cell walls. It is therefore consumed regularly in the diet, not contributing any calorific value but acting as a natural dietary fiber. Its use as an ingredient, however, is somewhat limited to ‘filler’ type roles or as a bulking agent as good solvents are not suitable for food use. Mechanical abrasion by ball milling can render an amorphous powder which, when the recrystallisation kinetics are known, may be utilized in a Binder Jetting 3D process to create edible cellulose-based structures.
