| titleOfInvention | 3D printing method and double-bundle 3D printing equipment |
| abstract | The invention relates to the field of 3D printing, in particular to a 3D printing method and a double-bundle 3D printing device. The 3D printing method comprises the following steps: delivering printing material to a printing beam nozzle; driving a printing beam nozzle to move and spray printing materials to form a printing layer on the substrate; repeating the above operation to form a plurality of printing layers stacked up and down on the printing layer; and irradiating the interfaces between the substrate and the printing layer and between the printing layer and the printing layer by adopting strong pulse energy beams/particle beams to form a continuous gradient transition layer at the interface, thus obtaining the ink. According to the 3D printing method, the interface is subjected to cold processing by adopting the intense pulse energy beams/particle beams, atoms at the interface are instantly diffused, melted and solidified to form the continuous gradual transition layer, the sudden change of thermal and mechanical properties on the interface, the thermal stress generated by hot processing and the lattice defects on printing points, lines and surfaces are eliminated, and the service life, high temperature resistance and high pressure resistance of a 3D printing additive product are greatly prolonged. |
