Ceramic particle preparation process for laser sintering ceramic 3D printing
The invention discloses a ceramic particle preparation process for laser sintering ceramic 3D printing. The ceramic particle preparation process comprises the steps of raw material treatment, adhesivepreparation, raw material mixing, spray granulation and heating drying treatment. According to the method, the particle diameter of the ceramic particle raw material is controlled in the grinding process in the ceramic particle preparation process, and the treated ceramic particle raw material is screened after grinding, so that the particle size of the raw material is ensured to be within a proper range, and the method satisfies the requirements of a laser printer on materials in the laser sintering preparation process. By adopting a spray granulation process, ceramic particles are uniform and fine, so that the stable performance of the material in the printing process is ensured, and the material is more uniform during the sintering; in addition, the ceramic particles are heated and dried after spray granulation, so that stable ceramic particles are obtained, and the ceramic particles prepared by the process are good in use effect, high in strength and easy to popularize.
本发明公开了一种用于激光烧结陶瓷3D打印的陶瓷微粒制备工艺，包括原料处理、粘接剂配制、原料混合、喷雾造粒与加热干燥处理步骤；本发明通过在陶瓷微粒制备的工艺中添加研磨过程中对陶瓷微粒原料的微粒直径进行控制，并在研磨后对经过处理的陶瓷微粒原料进行筛分处理，从而保证原料粒径在合适的范围内，以适应激光烧结制备过程中激光打印机对材料的要求；通过采用喷雾造粒的工艺使得陶瓷微粒均匀细腻，进而保证材料在打印的过程中性能稳定、烧结过程更均匀；另外在喷雾造粒后对陶瓷颗粒进行加热干燥处理，从而获得稳定的陶瓷微粒，也使得本工艺制备的陶瓷微粒使用效果好、强度高且易于推广。
