Polylactide composite materials with organic filler-modifier starch, inorganic filler -calcium carbonate and plasticizer - epoxidized soybean oil for 3D printing have been developed. On the basis of the modular deformation method of calculation the elastic-plastic and deformation properties of the developed modified polylactide materials are determined. The change of modulus of deformation, modulus of elasticity, modulus of high elasticity depending on the composition of the composite is revealed. The surface hardness, Vicat softening point and thermomechanical characteristics of the developed polylactide materials are determined
