Description

Technical Field

[0001] The utility model relates to the technical field of powder material processing, in particular to a powder material melting chamber. Background Art

[0002] The powder melting chamber is a place specially used to melt powder materials into the required shape. In the powder melting chamber, the powder materials are put into the processing cavity of the powder fusion machine. Then, the heat energy (such as laser beam or electron beam) is focused on the powder to raise its temperature above the melting point. At high temperature, the powder particles are partially melted, and due to the effect of surface tension, the powder particles form a certain bond. At the same time, the machine will also apply a certain pressure to maintain the close contact of the powder particles and promote melting.

[0003] The existing powder melting chamber only has the function of melting powder when in use. When the powder needs to be colored, a separate device is required, which results in low functionality of the powder melting chamber when in use and reduces the processing efficiency of the powder.
