In a process for the production of a structure comprising crystalline cellulose (10), cellulose (10) -forming organisms are at least partly cultured in a hollow mould (5). The hollow mould (5) is produced by means of a 3D printer (1), which builds up at least a part (2a, 2b) of the hollow mould (5) in layers from a modelling material.
