Abstract
A 3D printing method for an impact-resistant gradient complex part containing a hollow ceramic sphere complex, wherein the method includes the following steps: 1) designing the size and shape of the part as well as an internal layered structure; 2) providing a raw material, wherein the raw material contains a high polymer, a curing agent and hollow ceramic spheres; and 3) providing the raw material with a certain thickness according to a design, then, curing the raw material by using a heat source to form a high polymer layer containing the hollow ceramic spheres, and repeatedly printing the high polymer layer according to the design until the high polymer layer reaches the designed thickness to form the impact-resistant gradient complex part.
