Photocuring printing silicon carbide and preparation method thereof
The invention provides light-cured printing silicon carbide and a preparation method thereof, and relates to the technical field of additive manufacturing. The preparation method of the light-cured printing silicon carbide provided by the invention comprises the following steps: sequentially carrying out ball pressing granulation, curing, airflow crushing, modification, heat treatment, fumigation bleaching treatment and the like on submicron green silicon carbide to obtain silicon carbide powder with a composite structure; the printing paste containing the silicon carbide powder is subjected to photocuring printing and sintering, and photocuring printing silicon carbide is obtained. The submicron green silicon carbide powder is subjected to a series of treatment to prepare the silicon carbide powder with a composite structure, in the paste mixing process, the composite structure of the silicon carbide powder is not dispersed, a modified liquid phase layer is not prone to falling off, and the defects that silicon carbide powder with the fine particle size severely absorbs a light source and is not prone to falling off are overcome. And the prepared photocuring printing silicon carbide has the advantages of easiness in photocuring, few defects, easiness in sintering and high finished product density.
本发明提供了一种光固化打印碳化硅及其制备方法，涉及增材制造技术领域。本发明提供的光固化打印碳化硅的制备方法，包括以下步骤：对亚微米绿碳化硅依次经压球造粒、固化、气流破碎、改性、热处理、熏蒸漂白处理等，得到具有复合结构的碳化硅粉体；将包括所述碳化硅粉体的打印膏料进行光固化打印和烧结，得到光固化打印碳化硅。本发明通过对亚微米绿碳化硅粉体进行一系列的处理，制备得到具有复合结构的碳化硅粉体，混膏过程中，碳化硅粉体的复合结构不散，改性液相层不易脱落，克服了细粒径碳化硅粉体对光源吸收严重，难以打印和粗粒径粉体烧结活性低、生坯密度低的问题，制得的光固化打印碳化硅具有光固化容易、缺陷少、易于烧结和成品密度高的优点。
