3D printing forming and curing method
The invention belongs to the technical field of additive manufacturing, and particularly relates to a silicon carbide binder spraying 3D printing forming and curing method and a dipping recarburization process. A silicon carbide part green body is printed through a 3D printing technology, and then the carbon content of the silicon carbide green body is increased through an impregnation recarburization technology; and further sintering through a reaction sintering process to finally obtain a silicon carbide product which is high in strength and meets the technical requirements. By adopting the method provided by the invention, on one hand, the production cost can be reduced, and the production efficiency is improved; on the other hand, the silicon carbide powder can be utilized to the maximum extent, so that waste of the silicon carbide powder is reduced; and meanwhile, various silicon carbide products with complex sizes and shapes can be printed through binder jet 3D printing, and the requirements of various industries for the silicon carbide products are met.
本发明属于增材制造技术领域，特别涉及一种碳化硅粘结剂喷射3D打印成型与固化方法与浸渍增碳工艺；通过3D打印技术来打印碳化硅零件生坯，再经过浸渍增碳工艺，增加碳化硅生坯的碳含量；进一步地通过反应烧结工艺烧结，最终得到高强度、满足技术要求的碳化硅产品。采用本发明提供的方法步骤，一方面可降低生产成本，提高生产效率；另一方面可使得碳化硅粉末能够最大化利用，以降低碳化硅粉末的浪费；同时粘结剂喷射3D打印能够打印各种尺寸形状复杂的碳化硅制品，满足各行业对碳化硅产品的需求。
