Microstereolithography-Based Fabrication of Anatomically Shaped Beta-Tricalcium Phosphate Scaffolds for Bone Tissue Engineering

Figure 3

The negative UV-cured resin mold fabricated by microstereolithography. (a)–(c): the mold for scaffolds without cortical design; (d)–(f): the mold for scaffolds with cortical design. (a) and (d) are the side views; (b) and (e) are the top views; (c) and (f) are the bottom views. (g) and (h) showed the location of boxes in (b) and (e) by larger magnification. (i) showed the edge design for producing the cortical bone-like structure, where the box area in (h) was amplified. The white arrow indicates one of the lattice struts connecting between the internal lattice network and the outer shell.
