The present invention provides application of a self-healing material in 3D printing. In the present invention, a self-healing material is taken as a 3D printing material, and the material is intelligently detected and spontaneously healed by utilizing a self-healing function of the self-healing material, so that a potential damage to the self-healing material caused by generated micro-cracks can be prevented. Compared with molding conditions of a product, gentle and mild conditions are required for self-healing, and the overall performance of the product cannot be affected from beginning to end of a self-healing process, thereby reducing the maintenance cost of the product, prolonging the service life of the product, and increasing the utilization rate of resources.
