Fabrication of 3D scaffold based on CP in paramagnetic medium by using the magnetic field (the concentration of gadolinium salt is 3 M). (а) Schematic showing of recrystallization stages. (b) SEM image shows the surface of initial α-TCP particles (bar 10 μm). (c) SEM image shows the DCPD phase (bar 10 μm). (d) SEM image shows the surface of the obtained scaffold (OCP phase) (bar 10 μm). (e) X-ray phase analysis of α-TCP particles. (f) X-ray phase analysis of 3D scaffold after phase 1 of magnetic levitation fabrication (20 h in buffer № 1, RT). (g) X-ray phase analysis of 3D scaffold after phase 1 (20 h in buffer № 1, RT) and phase 2 (20 h in buffer № 2, RT) of magnetic levitation fabrication.
