  A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate, about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, and a tackifier, a transition temperature measured as the temperature immediately before phase change, based on viscosity measurement, is less than about 65° C. A system for additive manufacturing includes such a support material and a build material, the ratio of C12 to C18 fatty alcohol ethoxylate to C16 to C22 fatty alcohol is selected for property matching of the support material to the build material. A method of additive manufacturing includes providing such a system and printing via an inkjet printer the support material and the build material to provide a precursor to a three-dimensional printed article.

  一种用于增材制造的支撑材料包括大于约30重量％至约70重量％的C12至C18脂肪醇聚氧乙烯醚、约30重量％至约70重量％的C16至C22脂肪醇和增粘剂，根据粘度测量，其转变温度为紧接相变前的温度，小于约65℃。一种用于增材制造的系统包括这样一种支撑材料和构建材料，C12 至 C18 脂肪醇乙氧基化物与 C16 至 C22 脂肪醇的比例是为支撑材料与构建材料的性能匹配而选择的。增材制造方法包括提供这样的系统，并通过喷墨打印机打印支撑材料和构建材料，以提供三维打印物品的前体。
