The results of 3D printing. The general views of 3D printing entities. The cylindrical scaffolds with a diameter of 8 mm and height of 10 mm were made. The pore size and the changing rate were obviously different in (A) D1, (B) D2 and (C) D3. The SEM micrographs show the surface morphology of the (D) top views and (E) the lateral views of the three groups (Scale bar: 500 μm). (F) The strain–stress curve calculated by FE simulation. 3D = three-dimensional; FE = finite element; SEM = scanning electron microscope.
