3D printing forming method based on ceramic material
The invention relates to the technical field of ceramic 3D printing, in particular to a 3D printing forming method based on a ceramic material, which comprises the following steps: mixing various raw materials in proportion to prepare a premixed solution; adding ceramic powder and a dispersing agent into the premixed liquid, and continuously mixing to obtain a mixed material; extruding, cooling and granulating the obtained mixed material to obtain a ceramic feed; performing extrusion, wire drawing and cooling on the obtained ceramic feed to obtain a ceramic wire for 3D printing; the obtained ceramic wire is used as a raw material, 3D printing machining forming is utilized, and a ceramic green body is prepared; and degreasing and sintering the prepared ceramic green body to obtain the final ceramic device. The 3D printing forming method based on the ceramic material is suitable for machining and forming of all ceramic powder, is a ceramic additive manufacturing technology with a wide application range, and overcomes the defect that 3D printing technologies such as photocuring are only suitable for a small part of ceramic powder.
本发明涉及陶瓷3D打印技术领域，具体涉及一种基于陶瓷材料的3D打印成型方法，包括如下步骤：将各种原料按比例混炼配置成预混液；向预混液中加陶瓷粉体及分散剂，并继续混炼得到混料；将得到的混料挤出、冷却、造粒以制得陶瓷喂料；将得到的陶瓷喂料进行挤出、拉丝并冷却以制得3D打印用陶瓷线材；以得到的陶瓷线材为原材料，利用3D打印加工成型，制得陶瓷生坯；将制得的陶瓷生坯经脱脂烧结制得最终的陶瓷器件。本发明所涉及的基于陶瓷材料的3D打印成型方法适用所有陶瓷粉体的加工成型，是一种适用范围及广的陶瓷增材制造技术，解决了光固化等3D打印技术仅适用于少部分陶瓷粉体的缺点。
