Tool path optimization method for minimizing thermal unbalance in metal 3d printing

A tool path optimization system comprising:

• an input unit configured to input a parameter for setting equipment;
• and
• a processor configured to:
• generate stratum data by slicing a 3D model;
• generate tool path data comprising a moving path of a tool which is moved inside a stratum, by applying equipment settings to the generated stratum data;
