Various consolidation models have already been developed to predict the intimate contact of the composite material. But this consolidation models mainly developed for the conventional manufacturing processes (Moser, 2014). However, the validity for the 3D-printing process has yet to be proven and new models may need to be developed. The following process would be a first approach for a development of a 3D printing consolidation model (3DPCM): Initial calculations based on different consolidation models must be performed. With the first results, tests will be carried out and the results are compared with the theoretical values. Several iterations will be necessary to optimize the microstructure and mechanical properties of the material. These iteration loops, the consolidation model will be revised and the individual parameters (pressure, temperature, speed, ...) will be optimized (see Figure 10).
