Novel 3D printing mask

The invention provides a novel 3D printing mask. A mask keel of the mask is integrally formed by an elastic material through the 3D printing technology, the mask keel is detachably connected with a filtering layer, and the novel 3D printing mask has the main advantages that the mask keel can deform under the action of external force, and when a mask wearer wears the mask keel on the face through lacing belts, the filtering layer is tightly attached to the face of a wearer through deformation of the mask keel, so that personalized customization in the using process is achieved, and meanwhile the excellent protection effect is achieved. The elastic material used by the mask keel disclosed by the invention has the characteristics of being excellent in elastic property, safe to use, light in weight, comfortable to wear, reusable, more environment-friendly and capable of deforming under the action of external force, and the filtering layer of the mask is better fixed and attached to the face of a wearer.
