[Problem] To provide an active energy ray-curable resin composition for support materials which, during three-dimensional molding, prevents the corrosion of components of a molding apparatus, enables the molding of a large-sized product including side surfaces and corners with high accuracy, and also enables the efficient removal of support materials after molding, and an ink for a support material comprising the resin composition, and similar materials.
[Solution] By using the active energy ray-curable resin composition for three-dimensional molding support materials comprising 0.1 to 90 % by mass of a non-polymerizable compound (A) in which inorganic groups/organic groups (I/O value) equals 0.4 to 1.8, and 10 to 99.9 % by mass of a polymerizable compound (B) in which inorganic groups/organic groups (I/O value) equals 0.8 to 3.0, an ink for a support material having well-balanced inorganicity and organicity is obtained, and by using the ink, the support material is easily removed from a roughly molded product without corrosion of ink tanks, ink ejection heads, and similar objects, and a large-sized and highly accurate three-dimensional molded product is obtained.
[问题]提供一种用于支撑材料的活性能量射线固化树脂组合物,该组合物在三维模塑过程中可防止模塑设备部件的腐蚀,能够高精度地模塑包括侧表面和拐角在内的大型产品,还能够在模塑后有效地去除支撑材料,以及提供一种包含该树脂组合物的支撑材料油墨和类似材料。
[解决方案]通过使用活性能量射线固化树脂组合物,用于三维成型支撑材料,该树脂组合物包含 0.1 至 90% 的不可聚合化合物 (A)(其中无机基团/有机基团(I/O 值)等于 0.4 至 1.8)和 10 至 99.9% 的可聚合化合物 (B)(其中无机基团/有机基团(I/O 值)等于 0.通过使用该油墨,可轻松地从粗模塑产品中去除支撑材料,而不会腐蚀油墨罐、油墨喷射头和类似物体,并可获得大尺寸和高精度的三维模塑产品。
