In this article, the development of microcellular structure foams has developed by integrating the two successful and existing technologies, namely CO₂ gas batch foaming and Fused Deposition Modeling (FDM) 3D printing technique. It is a novel approach to manufacture complex design porous products for customized applications. The eventual cell morphologies of the extruded 3D printing filament depends on the process parameters pertaining to both microcellular foaming and 3D printing processes. Further, morphological study has been conducted to evaluate the cell morphologies of the 3D printing filament developed through customized FDM setup. During this process, the significance of various process parameters including saturation pressure, saturation time, desorption time, feed rate and extrusion temperature were thoroughly studied. To pursue this study base material used was acrylonitrile butadiene styrene (ABS). The 3D printed filaments consisted of cells with an average cell size in the range of 2.3–276 µm and the average cell density in the range of 4.7 × 10⁴ to 4.3 × 10⁹ cells/cm³. Finally, it has found that by controlling the process parameters different cell morphologies can be developed as per the end application.

在本文中，微孔结构泡沫的开发是通过整合两种成功的现有技术，即 CO ₂气批发泡和熔融沉积建模 (FDM) 3D 打印技术。这是一种为定制应用制造复杂设计的多孔产品的新方法。挤出的 3D 打印长丝的最终细胞形态取决于与微孔发泡和 3D 打印工艺相关的工艺参数。此外，还进行了形态学研究，以评估通过定制 FDM 设置开发的 3D 打印灯丝的细胞形态。在此过程中，深入研究了各种工艺参数的重要性，包括饱和压力、饱和时间、解吸时间、进料速度和挤出温度。为了进行这项研究，使用的基础材料是丙烯腈丁二烯苯乙烯 (ABS)。⁴至 4.3 × 10 ⁹细胞/cm ³。最后，发现通过控制工艺参数，可以根据最终应用开发不同的电池形态。
