3DP manufacturing method of aluminum oxide ceramic part based on aluminum chloride as binder
The invention relates to the field of additive manufacturing, in particular to a 3DP manufacturing method of an aluminum oxide ceramic part based on aluminum chloride as a binder, which comprises the following steps: mixing aluminum oxide, aluminum chloride and a mineralizer to obtain 3DP prefabricated powder; absolute ethyl alcohol and deionized water are mixed and then degassed, and the adhesive for printing is obtained; the 3DP prefabricated powder and an adhesive are used for ceramic part printing, and a ceramic part green body is obtained; and sintering the ceramic part green body to obtain the formed ceramic part. According to the method, aluminum chloride is used as a binder, the porosity-controllable ceramic part is formed, 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，具体涉及一种基于氯化铝作粘结剂的氧化铝陶瓷零件的3DP制造方法，包括如下步骤：将氧化铝、氯化铝以及矿化剂混合，得到3DP预制粉末；将无水乙醇和去离子水混合后除气，得到打印用粘接剂；利用3DP预制粉末及粘接剂进行陶瓷制件打印，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。本发明利用氯化铝作为粘结剂，进行孔隙率可控的陶瓷零件成型，并通过合适的后处理工艺，获得优良性能的陶瓷零件。
