陶瓷坯体3D塑性成形及原料性能研究

Study on 3D plastic forming and material properties of ceramic

适用于各类陶瓷材料的3D打印技术及装备成为研究热点.本文提出了一种适用于陶瓷洁具及陶瓷艺术品坯体成形的陶瓷3D打印新技术—挤出堆积成形技术.采用塑性陶瓷泥料进行挤出堆积试验.通过改变陶瓷泥料含水率及甲基纤维素含量,研究挤出泥料的可塑性和坯体抗弯强度,以此为基础,通过选择打印装备及打印系统,调试打印参数,利用陶瓷泥料打印测试,最终实现了复杂造型的陶瓷坯体3D塑性成形.

Currently,various types of printing technology and equipment which applicable to all kinds of ceramic materials is becoming a research hotspots.A new technology of ceramic 3D printing named Extrusion Deposition Modeling technology was proposed which applied to the green body forming of ceramic ware and ceramic artwork.The plastic ceramic clay was used during the extrusion deposition test.The plasticity of the extruded mud and the flexural strength of the green body were studied by changing the moisture content of the ceramic clay and the content of methylcellulose.On this basis,by selecting the printing equipment and printing system,debugging printing parameters,using ceramic clay for printing test,the 3D plastic forming of ceramic green body with complex modeling was ultimately achieved.
