FIELD: technological processes.
SUBSTANCE: invention relates to the additive printing process. In the numerical simulation method for identifying the way to use the modifying agent in the 3D printing process, 3D object layer thermal diffusion model is created, which must be formed from the part of the able to sinter material using the 3D printing method. Thermal diffusion model is created by a computer running under computer-readable instructions, stored on a non-temporary, material computer-readable medium. Amount of the modifying agent, which must be selectively applied, is calculated by the computer based on the thermal diffusion model.
EFFECT: technical result of the invention is prevention of the three-dimensional object coalescing spreading.
