FIELD: process engineering.
SUBSTANCE: method of producing 3D objects (W) made up of superimposed layers (L) of main material (M), liquid at ambient temperature and capable to harden at stimulating radiation. Said method comprises the following steps: distribution of layer (L1) of main material (M) on previous layer (L), selective stimulation of layer (L1) at one or several sections (K), repetition of aforesaid steps for every next layer of 3D object (W), cooling layers (L) to preset temperature lower than ambient temperature prior to stimulation for hardening of main material (M). In comprises also distribution of main material main layer (L0) prior to distribution of first layer of 3D object (W). Note here that main layer (L0) is not subjected to stimulation.
EFFECT: higher efficiency.
