FIELD: electrical engineering.
SUBSTANCE: invention relates to layer-by-layer printing systems. Method for forming a three-dimensional object includes supplying energy to the layer of the supplied model material to cause coalescence and solidification of the first layer portion of the first pattern. Cooling agent may be selectively supplied to the second portion of the model material layer to lower the temperature of the second layer portion of the second pattern. Second pattern is derived from data showing the measured temperature distribution of the layer or reflecting the temperature distribution predicted by the thermal process model. In addition, the first and second patterns do not depend on each other.
EFFECT: technical effect: higher quality of finished parts.
