FIELD: performing operations.
SUBSTANCE: invention relates to additive manufacturing. Method comprises forming a stepped structure of an article with a height of one layer from 10 to 200 mcm and a number of steps in each layer from 2 to 40 by means of stepped polymerisation with ultraviolet radiation according to given sections of its digital geometric model through stencils with alternation for each step of ultraviolet blocking sections. Polymerisation is carried out in a bath with an optically transparent bottom made from an elastically deformable film on top of which there is a thin layer of polymethylsiloxane with viscosity of not less than 10,000 cSt.
EFFECT: invention can be used for producing functional articles from photopolymer compositions.
