An induction heating fuse wire and laser compound based additive manufacturing device comprises a bottom plate, wherein a transverse circular plate is arranged at the upper part of the bottom plate; acircular ring sleeves the outer circumference of the circular plate and is movably connected to the outer circumference of the circular plate through a bearing; a plurality of uniformly-distributed induction heating devices are arranged at the bottom part of the circular plate; the lower ends of the induction heating devices are pointed to a part where a central axis of the circular plate is connected to the top surface of the bottom plate; vertical rods are fixedly mounted at the upper ends of the induction heating devices, and the side parts of the vertical rods are connected to the side part of the circular ring by hinging. According to the device, an induction heating fuse wire and laser compound based additive manufacturing method is used for performing additive manufacturing; a fusewire is molten by induction heating; a laser beam is capable of promoting the stirring in a metal melting pond; the material feeding capacity per unit of time is high in the manufacturing process, and the formed metal melting pond is large, so that the additive manufacturing efficiency is high; and meanwhile, the fuse wires manufactured through a plurality of materials can be synchronously fed, so that the additive manufacturing of an alloy material is achieved; and a novel device and a novel method are provided to realize additive manufacturing.

An additive manufacturing process for metal parts, comprising the following steps: S101: slice a prefabricated three-dimensional model; S102: generate an additive deposition path corresponding to each layer of the three-dimensional model slice; S103: slice each layer corresponding to the three-dimensional model The additive deposition path generates the additive molding path and the laser scanning path; S104: The molding machine drives the material box according to the additive molding path; S105: The material box releases the metal powder according to the additive molding path; S106: The molding surface corrector controls the metal powder Carry out shaping; S107: The material recovery box recycles the rejected metal powder; S108: The forming surface preheater preheats the forming surface formed by the metal powder; S109: If the forming surface is preheated, the laser former is turned on; S110: Laser forming The laser scan path is acquired by the laser shaper, and the laser shaper scans and shapes the metal powder on the preset molding surface along the preset laser scanning path at a preset scanning speed; S111: loop steps S104‑S110 until the parts are piled up and formed layer by layer .

The invention discloses an additive manufacturing method for a metal-based particle reinforced member. The method includes the steps that metal is melted in a crucible with a nozzle at the bottom, and then ceramic particles are added; a horizontal base plate which can make three-dimensional movement is arranged, and a control program of the horizontal base plate is set; and certain pressure is applied to enable metal melt containing the ceramic particles to flow out from the nozzle, the melt is solidified layer by layer, and the layers of melt are stacked to form a product. According to the method, the ceramic particles which do not chemically react with the metal melt are added, the viscosity of the melt is controlled through the size and volume fraction of the ceramic particles, the purpose of controlling flowing and forming is achieved, and the problems that in the prior art, interlayer bonding is poor, and forming is affected are solved; and the additive manufacturing method is a novel method for preparing the metal-based particle reinforced member.
