Abstract: A method of forming a scaffold is disclosed herein. In some embodiments, a method of forming a scaffold includes dissolving a polymer in a solvent to form a polymer solution; adding additive precipitating agent to the polymer solution; precipitating and expanding the polymer from the polymer solution to form a scaffold; and removing the solvent from the scaffold. In some embodiments, prior to adding the precipitating agent, the method further comprising adding at least one of calcium phosphate or a bioactive additive to the polymer solution to form a mixture including the polymer solution and the at least one of calcium phosphate or bioactive additive.
