Method for manufacturing ceramic part through photocuring additive
The invention discloses a method for manufacturing a ceramic part by a photocuring additive, which comprises the following steps of: 1, preparing a resin premixed solution, specifically, the mass of an organic solvent which does not participate in photocuring reaction is 20-40% of the mass of the resin premixed solution, and photosensitive resin is formed by mixing monofunctional resin, bifunctional resin and trifunctional resin; 2, obtaining a photocuring additive manufacturing paste; 3, carrying out photocuring forming to obtain a green body; 4, cleaning the green body, and freeze-drying the green body until tiny holes appear on the surface of the green body; 5, thermal degreasing is carried out; and step 6, sintering. The invention aims to provide a manufacturing method for manufacturing a thicker part based on a photocuring ceramic additive manufacturing material.
本发明公开了一种光固化增材制造陶瓷部件的方法，步骤如下：第一步：配制树脂预混液，不参与光固反应的有机溶剂的质量为树脂预混液质量的20%～40%，光敏树脂由单官能团树脂、双官能团树脂和三官能团树脂混合而成；第二步：得到光固化增材制造膏体；第三步：进行光固化成形，得到生坯；第四步：清洗生坯，然后通过冷冻干燥，直至生坯表面出现细微孔洞；第五步：热脱脂；第六步：烧结。本发明的目的是提供一种基于光固化陶瓷增材制造材料、制造较厚部件的制造方法。
