| 在层和速凝技术原理的基础上，研制出一种适合陶瓷零件的快速成型设备，但该设备存在刚性不足，变形较大等
问题，为了解决该问题，对铺料台升降装置进行了改进，将铺料台单边支撑改为中间对称支撑方式，改进后的陶瓷零件快
速成型机加强了运行的可靠性和平稳性。在此基础上对设备的的特点、技术参数和适用范围进行了说明，并以制备
95A1203陶瓷凸轮件为例，对成型过程进行了实验，得到成型样品，在电镜下进行SEM测试，结果表明：烧结后样品层间
无分层迹象，说明样品已经烧结为一体，材料黏合程度符合要求；与传统陶瓷零件成型设备相比，新型陶瓷件快速成型机
提高了加工效率，降低了生产成本，达到了经济实用的目的。 |

| On the basis of technology of laminated coalition and rapid concreting prototyping, an equipment which was
suitable for rapid prototyping of ceramic parts was designed. but there were problems with the device. such as
insufficient rigidity, large deformation etc. In order to solve the problems. the lifting system for paving platform was
improved, and a new rapid prototyping machine for ceramic parts was obtained. The support method for paving platform
was improved form one side support to middle way and symmetrical support, and the reliability and operation was
enhanced after the structure was improved. On the basis of the equipment. the characteristics. technical parameters and
the application scope of the device were proposed, and the forming experiments for 95Al203 ceramic cam member was
carried out to obtain a sample. The SEM test was conducted with the electron microscope. The results show that there is
no stratification sign between the interlayer of the sintered samples, which demonstrates that the sample has been
sintered as a whole. and the bonding extend of the material was qualified for the requirements of the products.
Comparing to traditional ceramic parts of molding equipment. the new rapid prototyping machine for ceramic parts
improves the efficiency, and reduces the production cost. and reaches the economic and practical purposes. |
