3D printing of mineral-polymer structures based on calcium phosphate and polysaccharides for tissue engineering

Abstract

The principle of inkjet printing of three-dimensional structures with the given architecture on the basis of composite materials biopolymers/calcium phosphate compounds is implemented. Formation of the calcium phosphate phases takes place in the process of printing of matrix structures by the biopolymer suspensions in situ. The developed approach may be used for manufacturing personalized composite implants, which will make it possible to obtain higher qualitative values of the biological properties of materials, bringing them close to native bone tissue.
