Figure 4: The Effect of Fiber Diameter and Pore Size on 3D Porous Architecture. We plotted the range of fibers and their respective pore sizes for different electrospun fibers: red dotted line (electrospun copolyesters); blue dotted line (experimental and theoretical data); and green dotted line (electrospun polystyrene). The black dotted line represents the range of porous scaffolds made using free-formed polymer deposition. Although the ranges differ, in each case fiber diameter is proportional to pore size.
