Method for preparing ceramic material through ultraviolet light beam synchronous curing assisted direct writing 3D printing
The invention relates to a method for preparing a ceramic material through ultraviolet light beam synchronous curing assisted direct writing 3D printing. The method comprises the steps that 1, a three-dimensional model of the ceramic material is established; 2, gas is pushed to extrude slurry by using an air pump; 3, before printing is started, an irradiation point coincides with a beating material extrusion position, during printing, a point light source synchronously moves along with a printing needle, and after single-time printing is completed, a printer stops printing, the needle returns to the original position, an ultraviolet lamp point light source is turned off, and a high-power ultraviolet lamp is turned on for surface exposure till complete curing is achieved; 4, the printer adjusts height parameters according to the height of a specific printing layer, continuously prints one to two layers on the cured printing layer and exposes, and the operation is cycled until printing is completed; and 5, the printed and molded ceramic body is degreased and sintered according to a sintering system. The problems of non-uniform curing, printing wire breakage, local overexposure, accumulative defects and the like in the photo-assisted direct writing forming process can be solved.
本发明涉及一种紫外光束同步固化辅助直写3D打印制备陶瓷材料的方法，包括：步骤1，建立陶瓷材料的三维模型；步骤2，利用气泵推动气体挤出浆料；步骤3，打印开始前，使照射点与打浆料挤出位置重合，打印时，点光源随着打印针头同步移动，单次打印完成后，打印机即暂停打印，针头归位，关闭紫外灯点光源，并打开大功率紫外灯进行面曝光至完全固化；步骤4，打印机根据具体打印层的高度调整高度参数，在已固化的打印层上继续打印一至两层并曝光，如此循环操作直至打印完成；步骤5，对打印成型的陶瓷坯体按照烧成制度进行脱脂烧结。本发明可以解决光辅助直写成型工艺中固化不均匀，打印断丝，局部过度曝光，累积性缺陷等问题。
