Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] It should be noted that when a component is said to be "mounted on" another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left...

Abstract

The invention relates to a powder supply device and a powder supply method for a powder bed. The powder supply device comprises a support, a forming mechanism and a powder supply mechanism; the forming mechanism is arranged on the support and comprises a forming cylinder with an inner cavity and a lifting table capable of moving in an inner cavity of the forming cylinder, and a printing base plateis supported on the lifting table; the powder supply mechanism is arranged on the support and comprises a powder bin, a lifting unit and a powder laying unit, the powder bin is provided with an innercavity, an inlet and an outlet, and the inlet and the outlet are communicated with the inner cavity of the powder bin and located at the two opposite sides of the printing base plate respectively; and the lifting unit is provided with bearing elements which can move in the inner cavity so as to send powder out of the powder bin, and the powder laying unit is provided with powder laying elements which can move from the outlet to the inlet so as to push the sent-out powder. The powder supply device integrates powder storage, powder supply, powder laying and powder returning, and is compact in powder path, easy to control, reliable in control and high in powder supply speed; and residual powder can be directly recycled.

Description

technical field [0001] The invention relates to the technical field of powder bed 3D printing, in particular to a powder supply device and a powder supply method for a powder bed. Background technique [0002] Powder bed 3D printer is one of the important branches of additive manufacturing equipment. It adopts the forming principle of powder layer by layer and selective heating area powder, which makes powder bed 3D printer have high forming freedom, high dimensional accuracy, good surface quality, It has the advantages of low support structure dependence and simple post-processing. [0003] In recent years, 3D printers have become popular in the field of mass consumer goods manufacturing, and the popularization and application of 3D printers, in turn, has stimulated their upgrade to higher processing performance and better production efficiency. However, during the development of 3D printers, an important system that affects the performance of powder bed 3D printers: the p...
