Grid-controlled field emission electron beam device and ceramic additive manufacturing device and method
The invention provides a grid-control field emission electron beam device and a ceramic additive manufacturing device and method.The grid-control field emission electron beam device comprises a substrate, field emission cathode arrays and grid electrodes are arranged on the substrate, the field emission cathode arrays are arranged on the substrate in a square array mode, the grid electrodes are arranged on one column or one row of field emission cathode arrays in a sleeving mode, and the grid electrodes are arranged on the substrate. A pixel unit is formed at the intersection of the field emission cathode array and the grid electrode, the field emission cathode array and the grid electrode are respectively connected with an external power supply, and the pixel unit is excited through a passive matrix addressing method. The grid-control field emission electron beam device with the emission breadth capable of being flexibly adjusted and the total breadth range of 500mm * 500mm is used as an electron beam source to carry out whole-layer exposure and layer-by-layer curing forming on the material, so that the forming efficiency and the forming range are favorably improved.
本发明提供一种栅控场发射电子束装置及陶瓷增材制造装置及方法,栅控场发射电子束装置,包括基板,基板上设置场发射阴极阵列和栅极,场发射阴极阵列采用方形阵列式布置在基板上,一列或一行场发射阴极阵列上套设有栅极,场发射阴极阵列与栅极交叉处构成一个像素单元,场发射阴极阵列与栅极各自与外部电源连接,通过无源矩阵寻址的方法激发像素单元。以发射幅面灵活调节、总幅面范围达500mm×500mm的栅控场发射电子束装置作为电子束源对材料进行整层面曝光、逐层固化成型,将有助于提高成型效率及成型范围。
