Abstract

The invention discloses indirect additive manufacturing equipment and an additive manufacturing method thereof. The indirect additive manufacturing equipment comprises an extrusion mechanism, a pre-degreasing system, a Z-axis mechanism, an industrial control computer and a movement guide rail driving the extrusion mechanism or the pre-degreasing system to move towards an X axis and a Y axis, wherein the extrusion mechanism is connected with a feeding system, a part supporting plate is arranged below the movement guide rail, and a grease collecting system is arranged on the part supporting plate; and the Z-axis mechanism is used for driving the part supporting plate to move along a Z axis. According to the indirect additive manufacturing equipment, part of a binder is removed in advance through layer-by-layer catalytic degreasing; uniformly distributed and communicated micropores are formed in a green body under the condition that the strength of the green body is not damaged, so that the difficulty of removing a binder degreasing product from the green body is reduced, the participation of a subsequent independent pre-degreasing process is avoided, the degreasing period can be shortened, the production cost is reduced, degreasing is more thorough, and the risk of binder component residues is avoided.

Description

Technical field [0001] The present invention belongs to the technical field of forming equipment, relates to an indirect additive manufacturing equipment, and also relates to an additive manufacturing method of the above-mentioned additive manufacturing equipment. Background technique [0002] Indirect additive manufacturing technology combines powder metallurgy and additive manufacturing two major part forming process characteristics, and compared with powder metallurgy, it can save mold investment, and can avoid the intervention of high-energy beam heat source compared with additive manufacturing. The application prospects for forming parts of materials such as alloys, ceramics and composite materials are huge. The indirect additive manufacturing technologies that have been developed today are mainly based on melt extrusion, binder injection, droplet injection and light curing processes. . [0003] Among them, the indirect additive manufacturing technology based on the melt extr...
