Abstract

The invention belongs to the industrial-grade powder rapid manufacturing molding related technology field and discloses spray printing equipment suitable for selective melting molding under a wide temperature gradient. The spray printing equipment comprises an upper cover body, a lower cover body, a powder laying component, a spray printing component and a heating component, wherein the spray printing component and the heating component are connected, and the upper cover body is connected with a powder laying base plate to form a closed space used for containing components; the heating component includes a first directional heat radiator, a second directional heat radiator and a heating roller module; and the first directional heat radiator and the second directional heat radiator are connected to the upper cover body and are used for heating a powder in a powder laying area and the powder in a working area so as to heat the powder to be in a glassy state; the heating roller module isconnected to the spray printing component and the powder in the working area is compacted and is further heated at the same time, and a part, sprayed to an adhesive, of the powder in the working areais melted and cured. Precision is improved, forming quality is good, and applicability is high.

Description

technical field [0001] The invention belongs to the technical field related to the rapid manufacturing and molding of industrial-grade powder, and more specifically relates to a jet printing equipment suitable for selective melting and molding under a temperature gradient. Background technique [0002] Laser and other high-energy beam non-metallic 3D printing (namely selective laser melting SLM) is widely used in aerospace, mold and other fields, and has attracted the most attention, but there are still significant problems of low efficiency and high cost. Jet printing 3D printing uses nozzle jet forming, The advantages of high efficiency and low cost are obvious. [0003] At present, in the current powder 3D printing device, the printing unit works at room temperature, and the non-metallic materials are always in a powder state, and the printing unit sprays adhesive to the printing work area while moving. In this case, on the one hand, after the sample is formed by bonding...
