| Summary: | The work is devoted to the search for a scientific and technical solution for the creation of filaments based on hydroxyapatite and polycaprolactone for extrusion three-dimensional printing. Hydroxyapatite powders were obtained by chemical precipitation using microwave radiation, and the average particle size in the powder was determined. Options for creating a filament by extrusion based on a composition of hydroxyapatite and polycaproloctone for subsequent printing of scaffolds (temporary scaffolds necessary for the formation of new functional tissues) are proposed. Images of the surface of calcium hydroxyapatite were obtained using a scanning probe microscope to assess the parameters of surface roughness, which is one of the most important factors for successful cell adhesion to the scaffold surface during osseointegration processes. |
