COMPOSITE FOR 3D-PRINTING OF MEDICAL PRODUCTS Russian patent published in 2019 - IPC A61L27/46 A61L27/48 

Abstract RU 2679127 C1

FIELD: chemistry.

SUBSTANCE: invention relates to composite materials for medical purposes, namely to high-molecular materials with phosphorus-containing inorganic fillers, and can be used for the manufacture of medical products by 3D printing through layer-by-layer deposition of the material melt. Composite for 3D printing of medical devices contains polylactide, hydroxyapatite with a dispersion of 20–100 nm and glycerin in the following ratio of components, wt.%: polylactide 12.5–98.9; hydroxyapatite 1.0–75.0; glycerol 0.1–12.5.

EFFECT: increasing the strength and improving the biological properties of medical devices made of a composite of the proposed composition.
