| titleOfInvention | Device and method for 3D printing oriented crystal parts using multi-beam laser-assisted temperature control |
| abstract | The invention relates to a device and method for 3D printing oriented crystal parts using multi-beam laser-assisted temperature control, which includes a laser, a beam expander, a scanner and an f-θ mirror connected by optical paths in sequence, and the laser emitted by the laser passes through the beam expander and the f-θ mirror. The scanner forms the main laser beam and several auxiliary laser beams distributed around the main laser beam; the f-θ mirror is set on the top of the forming chamber, the forming chamber is filled with protective gas, the forming chamber is connected to the powder feeding system and the bottom of the forming chamber It communicates with the forming cylinder, and the bottom of the forming cylinder is provided with a feeding device. The present invention forms a main laser beam and several auxiliary laser beams through a laser and a scanner, can form multiple mixed and synchronously scanned lasers, can adjust the temperature gradient direction of the molten pool during the forming process, and is conducive to the formation of directional solidified columnar crystal structures; at the same time The combination of the main laser beam and the auxiliary laser beam can change the temperature gradient, reduce the temperature gradient of the printing layer, and ensure the continuous and stable growth of metal crystals. |
