1. A method of designing and manufacturing a component in a computer-aided design and manufacturing environment, the method comprising:
obtaining, by a processor, a geometric model of a component from a geometric model database;
determining, by the processor, a plurality of orientation parameter values associated with the component, wherein the plurality of orientation parameter values defines a plurality of orientations of the component during additive manufacturing of the component;
performing, by the processor, a volumetric analysis of the component based on the plurality of orientation parameter values associated with the component using the geometric model of the component, wherein the volumetric analysis comprises:
determining an evaluation point on the geometric model of the component;
computing a heating volume around the evaluation point on the geometric model of the component based on a laser power and a material used to print the component, wherein the heating volume is a half sphere centered at the evaluation point such that an opening of the half sphere lies in a build direction; p2 computing an intersect volume that intersects a component volume and the heating volume around the evaluation point on the geometric model of the component, wherein the component volume is a volume of the component already printed at a time of printing the component at the evaluation point; and
computing a volumetric ratio of the intersect volume and the heating volume around the evaluation point;
computing, by the processor, one or more overheating areas in the component based on whether the volumetric ratio determined in the volumetric analysis is less than a threshold;
generating, by the processor, a multi-dimensional visual representation of the geometric model of the component indicating the one or more overheating areas in the component;
computing, by the processor, a total overheating area in the component for each orientation of the plurality of orientations of the component;
comparing, by the processor, the total overheating area in the component for the plurality of orientations of the component;
determining, by the processor, an orientation of the plurality of orientations of the component with least total overheating area of the component based on the comparing;
generating, by the processor, a computer-aided design file for manufacturing the component using an additive manufacturing process, wherein the computer-aided design file comprises an orientation parameter value of the plurality of orientation parameter values indicating the orientation of the component with the least total overheating area in the component during the additive manufacturing process; and
manufacturing the component based on the generated computer-aided design file using the additive manufacturing process.
