NUMERICAL PROCESS SIMULATION OF ADDITIVE MANUFACTURING

摘要

Numerical process simulation of additive manufacturing to predict, prevent, or compensate for adverse AM process effects, wherein computational simulation of the process steps executed during additive manufacturing is carried out with parallel computing using several computing devices. The simulation result of the individual process steps, in particular the calculation of the process response of the part or structure due to a newly printed or added layer, is computed completely independently and in parallel with the simulation of the other process steps. The distortion (and overall state) of the part or structure after a number of process steps is computed as the superposition of the distortion (state) of the individual process steps.
