Abstract

Brushite cement obtained from α-Ca₃(PO₄)₂ and orthophosphoric acid in the presence of Mg(H₂PO₄)₂ with compressive strength of 18 MPa was armored with a framework with the Kelvin architecture made of polylactide by thermoextrusion 3D printing. It is shown that armoring of cement with polylactide framework allows one not only to increase the compressive strength of such a structure (up to 35 MPa) but also to significantly improve its deformability (up to 15%).
