Abstract

The invention discloses a power feeding device and a three-dimensional printing system with the power feeding device. The power feeding device comprises a powder storage tank, a vibration board, a vibration source, a powder receiving tank and a driving piece, wherein a containing cavity is formed in the power storage tank and a discharging port communicated with the containing cavity is formed in the powder storage tank; the vibration board is arranged below the discharging port and faces the discharging port so as to receive powder flowing out from the discharging port; the vibration source is connected with the vibration board so as to drive the vibration board to vibrate; a receiving cavity with the upper end opened is formed in the powder receiving tank, the powder receiving tank is movably arranged below the vibration board and between the receiving position and the discharging position, and the receiving cavity faces the vibration board in the receiving position so as to receive the powder fallen down through vibration of the vibration board; the driving piece is connected with the powder receiving tank so as to drive the powder receiving tank to move between the receiving position and the discharging position. The power feeding device has the advantages of being effective and stable in powder feeding and the like.

Description

technical field [0001] The present invention relates to a powder supply device for a three-dimensional printing system, and also relates to a three-dimensional printing system with the powder supply device. Background technique [0002] The 3D printing technology that uses laser or electron beam scanning to solidify the preset powder layer and manufacture 3D objects layer by layer is a new type of manufacturing technology. Typical 3D printing processes include laser selective melting and electron beam selective melting. The basic process steps include: the powder supply and paving system spreads the powder material into a thin layer on the working platform, and then the laser or electron beam moves on the powder, Selective sintering or melting of powdered materials. The above steps are repeated until the entire three-dimensional object is manufactured. Therefore, the stable supply of powder materials is very important, which is directly related to whether the forming can b...
