FIELD: additive manufacturing.

SUBSTANCE: additive manufacturing device for producing a three-dimensional object, an additive manufacturing method for producing a three-dimensional object, and a molded product are disclosed. The device contains a device for layer-by-layer application of a structural material layer by layer, an energy supply device containing a carbon monoxide laser and a device for supplying radiation to points of each layer that correspond to the cross section of an object in this layer. The device also contains a device for changing the laser power, which, when the laser power is increased, provides an increase in the power incident on a unit area of the structural material for a period of time less than 300 mcs and/or more than 50 ns, and/or when the laser power is reduced, it provides a decrease in power per unit of area of the structural material, for a period of time less than 100 mcs and/or more than 100 ns.

EFFECT: providing objects with a high resolution of fine details.
