Conformal drying method for 3D printing direct writing forming ceramic body
A conformal drying method for a 3D printing direct writing forming ceramic body is disclosed and comprises the steps that a ceramic primary blank is printed on a printing bottom plate flatly laid witha layer of hydrophobic film in a 3D mode, then the ceramic primary blank and the printing bottom plate are placed in a constant-temperature and constant-humidity environment together to be dried for6h, wherein the drying temperature and humidity are set according to a warping degree relational expression fitted by MATLAB, solid phase content is 18 to 22.29 percent, the constant temperature is 25-35 DEG C, and the relative humidity is 40-93%, the initial ceramic blank is separated from the hydrophobic film and is continuously dried at constant temperature and humidity for 12-15 hours, then the constant temperature is selected to be 25 DEG C, the relative humidity is selected to be 40%, drying is continued for 3 hours, the ceramic primary blank subjected to constant-temperature and constant-humidity drying is put into a drying oven, the temperature is set to be 100 DEG C and the blank is dried for 10-20 minutes, so that controllable deformation and micro-deformation of the 3D printingceramic can be achieved, and the mechanical property and the specific surface area of the 3D printing ceramic are greatly improved.
一种用于3D打印直写成形陶瓷坯体的保形干燥方法，先在平铺有一层疏水薄膜的打印底板上3D打印陶瓷初坯，再将陶瓷初坯与打印底板一起放入恒温恒湿环境中进行干燥，根据MATLAB拟合的翘曲度关系式设置干燥温度与湿度，其中固相含量为18～22.29％，恒温温度为25℃～35℃，相对湿度为40～93％，干燥6小时；使陶瓷初坯与疏水薄膜分离，对陶瓷初坯继续进行恒温恒湿干燥，干燥12～15小时；然后将恒温温度选择为25℃，相对湿度选择为40％，继续干燥3小时；将恒温恒湿干燥后的陶瓷初坯放入烘箱中，温度设置为100℃，干燥10～20分钟；本发明能够实现3D打印陶瓷的可控变形、微变形，大幅度提高3D打印陶瓷的力学性能与比表面积。
