光固化快速成形技术（SLA）因其具有良好的尺寸精度和位置控制能力而被认为是最有前途的陶瓷零件快速成形技术。悬浮液的流变行为和固化行为是陶瓷光固化成型的控制因素。本文研究了油酸（OA）、硬脂酸（SA）和聚丙烯酸铵（PAA-NH 4）作为HDDA悬浮剂的表面活性剂。改性氧化铝颗粒表现出不同的润湿性与HDDA单体，因此不同的流变行为和稳定性之间的配制悬浮液。在所有三种分散剂中，OA表现出最好的性能。40体积%的氧化铝悬浮液具有粘度（
Stereolithography (SLA) has been regarded as the most promising rapid prototype (RP) production method for ceramic parts recently because of its better precision in size and site control. The rheological behavior and curing behavior of suspensions are controlling factors for ceramic stereolithography. In this work, oleic acid (OA), stearic acid (SA) and Poly(Acrylate Ammonium) (PAA-NH4) were studied as the surfactant for HDDA-based suspension formulation. Modified alumina particles exhibit different wettability with HDDA monomer and thus the different rheology behavior and stability between the formulated suspensions. OA shows the best performance among all three dispersants. 40 vol% alumina suspensions with a viscosity (
