Detailed Description
The inventor considers that when printing directly by using the 3D printing device in the prior art, such as the fuse printing is needed to print 100cm 2 The product in the area takes about 2 minutes to print one layer, but because the heat energy and the temperature of the printing body obtained after printing one layer are very high, if the next layer is directly printed after finishing the printing of one layer, the generated heat energy plus the original heat energy can lead to printingThe printing body is melted and deformed to cause printing failure, so that the next layer printing production cannot be directly performed, and the next layer printing is performed after waiting for a certain time to lower the temperature of the substrate. And because the printing demands are different, the size and the shape of the printing body are different, the printing time and the waiting time of each layer are different, the miniaturization of the printed product is more complicated, the waiting cooling time is longer, the printing continuity is poor when the printing is carried out in the prior art, the printing period is long, and the time and the labor are wasted. In the actual metal 3D fuse printing process, the main cabin of the printing device is in a sealing state, and in the continuous long-time printing process, the high-temperature heat generated by plasma arc light gradually increases the temperature of the cabin, so that the functions and properties of equipment, a metal matrix and a printed product are affected. Therefore, the invention provides a metal 3D fuse printing on-line multidimensional temperature field control system, which is added on the basis of the existing 3D printing device to realize temperature control in the printing process, and further realize accurate adjustment of the process from high-temperature melting to cooling solidification of metal through real-time temperature field control in the printing process of the metal 3D fuse, so that the heat energy of a printed product can be accurately dredged and controlled. The three-stage control modes of strong jet flow temperature control, medium gradient conduction temperature control and weak turbulence temperature control are adopted to realize the combination mode of rapid temperature control/gradient temperature control/steady-state temperature control. So that the heat of the high-temperature metal printing body can be effectively removed in a grading way. And the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment provides an online multidimensional temperature field control system for printing a metal 3D fuse, which is shown in fig. 1 and 2 and comprises a metal molten pool temperature control system 1, a metal matrix temperature control system 2 and a fuse printing product temperature control system 3.

For example, the temperature of the molten metal bath 4 in the printing process is close to 2000 ℃, the temperature of the molten metal bath 4 is controlled by adopting the reverse on-track strong cooling of liquid argon so as to realize the rapid solidification and cooling of the printing body, and the process also controls the heating process of the current according to the depth and the area of the bath. For example, when 3D printing is performed in a plasma arc furnace, the cooling module 11 is arranged in the opposite same track of the plasma arc furnace, and the purger is preferably used as the cooling module 11, and the purger and the plasma arc furnace are arranged in the opposite same track, so that high-purity argon is purged through the purger, the forced rapid cooling of the metal molten pool 4 is realized through the purged liquid argon, and the extremely cold process does not generate oxidation and/or nitridation.
