The lightweight products with superior specific strength are in great demand in numerous applications such as automotive, aerospace, biomedical, sports, etc. This work focussed on the manufacturing of lightweight products using the cellular three dimensional (3D) printing process. In this work, the continuous microcellular morphology has been developed in a single foamed filament using 3 D printing of carbon-di-oxide (CO₂) saturated acrylonitrile butadiene styrene (ABS) filaments. The microcellular structures with average cell size in the range of 6–1040 µm were developed. The influence of printing parameters; nozzle temperature, feed rate, and flow rate on the foam characteristics and cell morphology at different levels were investigated. The different kinds of observed foamed extrudate irregularities were discussed.

具有优异比强度的轻质产品在汽车，航空航天，生物医学，体育等众多应用中都有大量需求。这项工作的重点是使用蜂窝式三维（3D）打印工艺制造轻质产品。在这项工作中，使用二氧化碳（CO ₂）饱和丙烯腈丁二烯苯乙烯（ABS）长丝。已开发出平均细胞大小在6–1040 µm范围内的微细胞结构。印刷参数的影响；研究了不同温度下的喷嘴温度，进料速度和流速对泡沫特性和泡孔形态的影响。讨论了观察到的不同种类的泡沫挤出物不规则现象。
