FIELD: technological processes.
SUBSTANCE: present invention relates to use of a thermosetting polymer powder composition in a selective laser sintering (SLS) method for producing thermosetting polymer 3D material, wherein the composition contains at least one curable polymer binder material, and during each run of the SLS method, the polymer binder material is at least partially cured inside the formed layer and at least partially cross-linked with the previous layer. Invention also relates to an SLS method which employs such a thermosetting polymer powder composition and to printed 3D article obtained using said thermosetting polymer powder composition.
EFFECT: disclosed is use of a thermosetting polymer powder composition.
