Embodiment Construction

[0036] The present invention is described in further detail below in conjunction with accompanying drawing:

[0037] see figure 1 , the present invention discloses a protective device for additive manufacturing and its use method. The device includes: a protective cover 4, an internal environment adjustment unit 2 and a dust and smoke processing unit 3; the protective cover 4 is made of a flexible transparent flame-retardant material, composed of It consists of two sides, one top and one bottom, and the adjacent sides of the protective cover 4, and between each side and the top are fixedly connected by air column 7; all air columns 7 can be connected in series, and are controlled by an air pump or multiple air columns. Each air pump provides air; it can also be independent, and the air is provided by a separate air pump; the protective cover 4 is supported by the air column 7, and the working platform 11 is wrapped by the bottom surface and four sides of the protective cover 4...

Abstract

The invention discloses an additive manufacturing protective device and a using method thereof. The device comprises a protective cover, an inner environment regulating unit which is communicated with the inner space of the protective cover, and a dust flue gas treatment unit, wherein the inner space environment regulating unit is used for replacing gas inside the protective cover, so that the environment inside the protective cover is protective atmosphere in a printing process; the dust flue gas treatment unit is used for discharging waste gas generated in the printing process; the protective cover is matched with a working platform for sealing a formed part between the protective cover and the working platform, so that the space of the protective device is reduced, and all spaces of the protective device are effective spaces. The device covers an effective working area, reduces replacement time and amount for working environment air in comparison with a mode that a conventional whole working device is placed in the effective working area, and effectively saves time and reduces operation cost; and the protective device is arranged on the working platform for use, so that movement is convenient.

Description

【Technical field】 [0001] The invention belongs to additive molding (the field of 3D printing), and in particular relates to an additive manufacturing protective device and a use method thereof. 【Background technique】 [0002] Additive manufacturing technology is a technology based on digital model files, using powdered materials or wire materials to construct objects by stacking and accumulating layer by layer. Commonly used additive manufacturing energy sources are: electron beam, laser, arc, etc. At present, the industry mainly adopts overall protection for the above heat sources, that is, the entire printing device is placed in a specific closed environment, and the air, water, oxygen and other components in the environment are controlled and monitored. [0003] The overall protection can effectively isolate the factors that affect the printing effect. For example, filter a large amount of toxic and harmful gases generated during printing, set up vents and exhaust fans,...
