The patent application (Publication Number: US20230391007A1) describes a method for heating during additive manufacturing that involves dividing a heating area into multiple strips within a layer of build material. These strips are randomly assigned indices, and energy is applied by an energy source across each strip in the order of the assigned indices. The energy source can be an electron beam, and the strips can have vectors indicating spatial positions and directions for energy application, including magnitude and speed.

Furthermore, the method includes dividing a second heating area into strips, randomly assigning indices, and applying energy in a similar manner. The heating areas correspond to cross-sections of objects in the build material, with potential overlap between areas. The method can be applied to the entire layer of build material or specific object cross-sections. Additionally, the patent application includes claims for a computing device and a non-transitory computer-readable medium configured to perform the heating method during additive manufacturing. These technologies aim to optimize the heating process in additive manufacturing for enhanced efficiency and precision.
