3D printer edge warping prevention structure

The utility model discloses a 3D printer edge warping prevention structure. The 3D printer edge warping prevention structure comprises a heating plate which is arranged in a 3D printer. A thermally-conductive flat plate is fixed on the heating plate in a binding manner. The thermally-conductive flat plate is provided with a coating for maintaining the temperature keeping state of a printing material. According to the utility model, the problem of edge warping due to bending deformation caused by the temperature difference problem between the printing material of the 3D printer and the heating plate can be solved, and the advantage of good practicability can be realized, so the 3D printer edge warping prevention structure is worth to be popularized.
