Fig 6
SEM of 3D fabricating bone scaffolds.
(A) SEM of the phosphoric acid scaffold. (B) SEM of the phosphoric acid scaffold. (C) High magnification (500 ×) images of the red rectangle in B. (D) SEM of the polyvinyl alcohol scaffold. (E) SEM of the polyvinyl alcohol scaffold. (F) High magnification (500 ×) images of the red rectangle in E. In A, and D, red circles indicate design porosity; yellow circles indicate the tiny gap between the powder particles.
