Abstract: A production method of a Fe16N2 based permanent magnet includes the following steps: 1) obtaining a Fe16N2 compound in a form of micro flakes by applying a nitriding process to ??-Fe powders of micro or nano sizes; 2) forming a structure by combining a polymer material with the Fe16N2 compound and utilizing a 3D printer; and 3) applying a magnetization process to the structure obtained in step 2 to obtain a magnetized structure and carrying out a heat treatment process to the magnetized structure to obtain the Fe16N2 based permanent magnet. The production method is continuous, less difficult, and less costly compared to the production of previous permanent magnets.
