Morphological evaluation of microcellular foamed composites developed through gas batch foaming integrating Fused Deposition Modeling (FDM) 3D printing technique

Abstract

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.

An Investigation on the Hardness of Polylactic Acid Parts Fabricated via Fused Deposition Modeling

“…Fused deposition modeling (FDM) is one of the most popular and used technique in additive manufacturing (AM) due to its simple operation, low cost, and variety of materials [ 1 , 2 , 3 , 4 ]. The FDM method is popular due to its highly flexibility and process speed, but the durability of the printed material is the major concern, especially for products applicated in an outdoor environment [ 5 ].…”

Lightweight and flexible sensors based on environmental‐friendly poly(butylene adipate‐co‐terephthalate) composite foams with porous segregated conductive networks

“…[19][20][21] Several approaches have been applied to manufacture the microcellular structure, including template, phase separation, 3D printing and bubbling methods. [22][23][24][25][26] Supercritical fluid foaming technology, as one of the bubbling methods, is considered as a facile and effective strategy to fabricate the porous structure with uniform cell size and large cell density in the polymer matrix. 27,28 Supercritical carbon dioxide (ScCO 2 ) has been widely applied in the polymer foaming filed, due to the mild critical condition, good compatibility with polymer matrix, low cost and environmental-friendliness.…”
