丙烯腈-丁二烯-苯乙烯（ABS）是熔融沉积成型（FDM）3D打印使用的最重要的材料之一。在这项工作中，我们通过简单的混合策略制备了一系列3D可打印的ABS基材料，这些材料具有更好的耐刮擦性和平衡的机械性能。在ABS中加入30质量份的聚甲基丙烯酸甲酯（PMMA），可同时提高ABS的耐刮擦性能、机械强度、熔体流动速率、硬度、透光率和表面光泽度。在ABS/PMMA体系中加入少量的核壳橡胶改性剂甲基丙烯酸酯-丁二烯-苯乙烯共聚物（MBS），可有效提高ABS/PMMA体系的韧性，且对ABS/PMMA体系的耐刮擦性能和光学性能影响不大。这种ABS/PMMA/MBS共混物具有大规模制造的潜力，可以开发为专门用于FDM 3D打印的新型热塑性聚合物材料。
Acrylonitrile butadiene styrene (ABS) is one of the most important materials utilized by fused deposition modeling (FDM) 3D printing. In this work, we prepared a series of 3D-printable ABS-based materials with improved scratch resistance and balanced mechanical performance via a simple blending strategy. The scratch resistant performance, mechanical strength, melt flow rate, hardness, transmittance, and surface gloss of ABS were improved simultaneously by adding 30 mass portion of poly(methyl methacrylate) (PMMA). Further addition of a small amount of methacrylate butadiene styrene (MBS), a kind of core shell rubber modifier with high toughening efficiency, improved the toughness of ABS/PMMA effectively and hardly influenced the scratch resistance and optical properties of ABS/PMMA. This ABS/PMMA/MBS blend has the potential for large-scaled fabrication and can be developed as a new category of thermoplastic polymer material specially used for FDM 3D printing.
