Abstract
A system and method for selecting processing parameters for build of one or more objects by additive manufacturing using simulation.
Claims12
A computer-implemented method for automatically selecting processing parameters for build of one or more objects using additive manufacturing, the method comprising:
- obtaining a job file corresponding to the one or more objects;
- extracting, from the job file, initial processing parameters for building the one or more objects;
- performing a 2D finite difference simulation for one or more layers of the one or more objects, wherein an input to the 2D finite difference simulation comprises the extracted initial processing parameters, and wherein an output of the 2D finite difference simulation comprises temperature as a function of time at one or more locations in the one or more layers;
- selecting processing parameters for building the one or more objects based on the temperature as a function of time at the one or more locations in the one or more layers, a first threshold corresponding to a lack of fusion, and a second threshold corresponding to overheating;
- and
- modifying the job file with the selected processing parameters, the job file being configured to cause an additive manufacturing device to build the one or more objects.
