Methods of producing hybrid fibrous scaffolds are provided. The methods include dissolving a polymer, such as polydioxanone, in a solution, such as 1,1,1,3,3,3-hexafluoro-2-propanol (HFP), to form a polymer-containing solution. The method comprises electrically charging the polymer-containing solution. The method comprises writing the polymer-containing solution on a counter electrode or a ground in a grid pattern to form semi-stable fibers comprised of the polymer, the semi-stable fibers vary between bent and straight and forming the hybrid fibrous scaffold. The writing may be performed by a 3D printer. The resulting scaffolds and methods of using the same are also disclosed herein.
