FIELD: medical devices.
SUBSTANCE: invention relates to compositions of high-molecular compounds, namely to biodegradable compositions of high-molecular compounds using phosphorus-containing compounds as components, and can be used for 3D printing of medical products. Polymer composite material for 3D printing of medical products contains ε-polycaprolactone with a number average molecular weight of 70,000–90,000 g/mol, hydroxyapatite with a particle size of 100–20,000 nm and polysorbate 20 in the following component ratio, wt.%: 76–98 of ε-polycaprolactone, 1–21 of hydroxyapatite, 1–3 of polysorbate 20.
EFFECT: obtaining a polymer composite material for 3D printing of medical products with elastic properties.
