A bio-printing process comprises a step of preparing a target digital model representative of the three-dimensional organization of the tissue to be produced, a step of controlling a bio-printing instrument for the deposition of a plurality of layers of living cells and of biomaterials, a step of calculation of a digital printing model as a function of the digital model of the product to be produced, and of a model predicting change, and also characteristics of the constituents to be printed. The step of controlling the bio-printing instrument is carried out according to the digital printing model calculated in this way. A system is also described for implementing this process.
