The invention belongs to the technical field of 3D printing, and particularly relates to inorganic slurry for direct writing forming and a preparation method of the inorganic slurry. The inorganic slurry for direct writing molding comprises Al2O3 powder, an inorganic dispersant, SiO2 micro powder and deionized water. The components used in the invention are all inorganic substances, and the prepared slurry can replace an organic binder added in the slurry for direct writing molding at present, so that the problems of blank cracking and density reduction caused by decomposition and discharge of organic matters in the sintering process can be avoided, and finally the compressive strength and breaking strength of a sample are improved; and the problem of environmental pollution caused by volatilization of organic matters can be avoided.
本发明属于3D打印技术领域，具体涉及一种直写成型用无机浆料及其制备方法。本发明的直写成型用无机浆料包括Al2O3粉末、无机分散剂、SiO2微粉和去离子水。本发明所用组分均为无机物，配制成的浆料能替代目前直写成型用浆料所添加的有机粘结剂，不仅可以避免有机物在烧结过程中因分解、排出而引起坯体开裂和致密度降低的问题，最终提高样品的耐压强度和抗折强度；而且还能避免因有机物挥发造成的环境污染问题。
