THREE-DIMENSIONAL STRUCTURES BASED ON HYDROXYAPATITE AND POLYURETHANE DIOL OBTAINED THROUGH 3D PRINTING TECHNOLOGY

摘要

The invention relates to 3D structures made by the 3D printing method, with the 3D BioScaffolder equipment at room temperature, having the shape of a cube with 2 cm side.;The 3D structures of the present invention are obtained from: hybrid powder based on hydroxyapatite and polyurethane diol synthesized by the hydrothermal process at a pressure p = 1000 bar and temperature t = 100 °C, in a weight ratio of 4: 1, in the form of spherical particles having a diameter of 0.5-8 µm; Mowiflex solution 20% and Baymedix FD 103 solution 57%.
