三维(3D)印刷方法
摘要：
在3D印刷方法中，施加可烧结材料并将其加热至约50℃至约400℃的温度。将聚结剂选择性地施加在所述可烧结材料的一部分上，并且将改性剂选择性地施加在所述可烧结材料的所述一部分上和/或另一部分上。所述改性剂由无机盐、表面活性剂、助溶剂、湿润剂、杀菌剂和水组成。将所述可烧结材料暴露于辐射，从而所述聚结剂至少部分地使与该聚结剂接触的可烧结材料的一部分固化，并且所述改性剂i)减少与聚结剂和改性剂两者接触的可烧结材料的一部分的固化、ii)防止与该改性剂接触的可烧结材料的另一部分的固化、或iii)i和ii两者。
摘要（英）：

In a 3D printing method, a sinterable material is applied and heated to a temperature ranging from about 50 DEG to about 400 DEG. A coalescent agent is selectively applied on a portion of the sinterable material, and a modifying agent is selectively applied on the portion and/or on another portion of the sinterable material. The modifying agent consists of an inorganic salt, a surfactant, a co-solvent, a humectant, a biocide, and water. The sinterable material is exposed to radiation, whereby the coalescent agent at least partially cures the portion of the sinterable material in contact with the coalescent agent, and the modifying agent i) reduces curing of the portion of the sinterable material in contact with both the coalescent agent and the modifying agent ii) prevents curing of the other portion of the sinterable material in contact with the modifying agent, or iii) both i and ii.
