Problems solved by technology

The disadvantages are: sometimes the molded parts will form micropore defects due to insufficient powder melting, the required powder materials are expensive, the use of materials has dust pollution problems, and the high-power lasers used are expensive and not durable enough
The disadvantage is: the material is heated by resistance wire, and the molding material used is generally thermoplastic, wax or artificial rubber with a low melting point. The molding material is mainly non-metal, and the strength is no

Abstract

The invention discloses an electromagnetic modulation fusion emitting device which comprises an induction heating coil, a three-phase linear induction heating coil and a spray nozzle, wherein the three-phase linear induction heating coil is arranged under the induction heating coil; a support cylinder is arranged at the periphery of the induction heating coil; the lower end of the support cylinder is connected with the spray nozzle; two ends of the induction heating coil are connected to an alternating power supply; the three-phase linear induction heating coil is arranged into a three-phase four-wire system circuit structure; four ends of the three-phase linear induction heating coil are respectively connected to a three-phase pulse alternating power supply. A levitation melting technology and a linear induction motor principle technology adopted by the electromagnetic modulation fusion emitting device are both common electromagnetic induction technologies in a traditional industry, the process is mature, the manufacturing cost and the durability are superior to those of a selected laser sintering (SLS) technology adopting a high-power laser, and the electromagnetic modulation fusion emitting device is more suitable for applicable in the traditional industry.

Description

technical field [0001] The invention relates to a three-dimensional molding manufacturing technology, and more specifically relates to an electromagnetic modulation melting emission device in the rapid manufacturing of fusion deposition. Background technique [0002] Among the existing three-dimensional modeling manufacturing technologies, the most widely used are selective laser sintering (SLS) and fused deposition modeling (FDM). Among them, the selective laser sintering technology is to first use the software to "cut" the 3D digital model of the part into several planes, which forms many sections. After the 3D model is sliced, in a container, one can be dropped. Firstly, the surface of the material roller is covered with a layer of material powder to be sintered. These powders can be made very fine, and then the high-power laser is controlled by software to select the bottom 3D slice shape data to start sintering. Then the platform moves down, and the material roll is la...
