3DP manufacturing method of aluminum oxide ceramic part
The invention relates to the field of additive manufacturing, in particular to a 3DP manufacturing method of an aluminum oxide ceramic part, which comprises the following steps: mixing aluminum oxide, aluminum dihydrogen phosphate, a curing agent and a mineralizing agent to obtain 3DP prefabricated powder; the 3DP prefabricated powder and water-based ink are used for ceramic part printing, and a ceramic printing part is obtained; integrally baking and curing the ceramic printing piece and the powder bed; the cured ceramic green body is sequentially subjected to powder cleaning, vacuum infiltration and drying treatment, and a ceramic product green body is obtained; and sintering the ceramic part green body to obtain the formed ceramic part. According to the invention, aluminum dihydrogen phosphate is used as a binder for forming the high-performance porous ceramic part, and the ceramic part with excellent performance is obtained through a proper post-treatment process.
本发明涉及增材制造领域，具体涉及一种氧化铝陶瓷零件的3DP制造方法，包括如下步骤：将氧化铝、磷酸二氢铝、固化剂和矿化剂混合，得到3DP预制粉末；利用3DP预制粉末以及水性墨水进行陶瓷制件打印，得到陶瓷打印件；对陶瓷打印件与粉末床进行整体烘烤固化；对固化之后的陶瓷生坯依次进行清粉、真空浸渗及干燥处理，得到陶瓷制件生坯；对陶瓷制件生坯进行烧结，得到成型陶瓷制件。本发明利用磷酸二氢铝作为粘结剂，进行高性能的多孔陶瓷零件成型，并通过合适的后处理工艺，获得优良性能的陶瓷零件。
