用于多孔材料快速成型的商用光敏树脂通常不适合不同的成型技术，因为移除模具需要在高达600℃的温度下进行热分解。在本研究中，开发了一种基于水溶性聚合物的树脂配方，并对其作为牺牲模具材料的可用性进行了评估。碱性单体二甲基丙烯酰胺具有快速固化和优良的聚合物溶解性能。甲基丙烯酸被发现是一种有用的共聚单体，可以提高机械强度和特征分辨率。通过添加聚乙烯吡咯烷酮作为填充剂和使用可水解性交联剂如甲基丙烯酸酸酐，后一种标准也得到了改进。(C)2005年威利期刊公司。
Commercial light-sensitive resins for Rapid Prototyping of cellular materials are often unsuitable for different molding techniques because removal of the mold uses thermal decomposition at temperatures of up to 600 degrees C. In this study, a resin formulation based on water-soluble polymers was developed and evaluated regarding its usability as sacrificial mold material. The base monomer dimethylacrylamide gave fast curing and excellent polymer solubility. Methacrylic acid was found to be a useful comonomer to improve mechanical strength and feature resolution. The latter criterion was also improved by adding poly(vinyl pyrrolidone) as filler and by using a hydrolytically cleavable crosslinking agent such as methacrylic acid anhydride.
