PURPOSE: A polymer drug delivery system of three dimensional shape and a method for preparing the same are provided to control drug release. CONSTITUTION: A method for manufacturing a polymer drug delivery system by inkjet printing method comprises: a step of mixing biocompatible polymers, drug, and organic solvent to prepare polymer ink; a step of injecting the polymer ink to a printer cartridge and mounting the cartridge to an inkjet printer; and a step of performing inkjet printing of polymer ink on a substrate. The organic solvent includes tetrahydrofuran, dimethyl aceteamide, dimethyl formamide, chloroform, dimethyl sulfoxide, butanol, isopropanol, isobutayl alcohol, tetra butyl alcohol, acetic acid, 1,4-dioxane, toluene, or dimethyl formamide. |
