Abstract

Additive manufacturing (AM) allows the production of the internal structure of porous media (PM) with porosity and permeability tailored for a specific application. Material extrusion (MEX) AM enables the fabrication of a lattice-type porous structure by varying process parameters, usually applying the zigzag raster filling strategy. In a recent study, a Variable Bead Width Porous Filling (VBWPF) strategy was proposed, which generates pores by changing the printing speed during filament deposition and resulting in a unique porous structure with less pore interconnectivity. Specific pores’ dimensions and distribution on the layer can be obtained with the strategy’s parameters. In this work, different configurations of the VBWPF strategy were produced, and their porosity and permeability were measured experimentally. A PM with traditional raster filling (lattice structure) was also printed and measured for comparison. The porous structures of different VBWPF configurations were analyzed with micro-computed tomography (µCT). The results showed that VBWPF parameters were able to modify the porous structure obtained, changing the porosity and permeability of the PM. The PM produced exhibited 27% lower porosity and 55% lower permeability than the traditional raster filling PM with similar pore widths. These unique characteristics open up the field for applications of PM obtained through AM.

在 MEX 填充策略中通过微珠宽度变化获得的独特多孔介质的渗透性和孔隙度分析

增材制造（AM）可根据特定应用生产具有孔隙率和渗透性的多孔介质（PM）内部结构。材料挤压（MEX）AM 可以通过改变工艺参数来制造晶格型多孔结构，通常采用之字形光栅填充策略。最近的一项研究提出了可变珠宽多孔填充（VBWPF）策略，通过改变丝沉积过程中的打印速度来产生孔隙，从而形成孔隙互连性较低的独特多孔结构。利用该策略的参数可以获得特定的孔隙尺寸和在层上的分布。在这项工作中，制作了 VBWPF 策略的不同配置，并通过实验测量了它们的孔隙率和渗透性。同时还打印并测量了传统光栅填充（晶格结构）的 PM，以进行对比。利用微计算机断层扫描（µCT）分析了不同 VBWPF 配置的多孔结构。结果表明，VBWPF 参数能够改变所获得的多孔结构，改变 PM 的孔隙率和渗透性。与孔隙宽度相似的传统光栅填充 PM 相比，所生产的 PM 孔隙率低 27%，渗透率低 55%。这些独特的特性为通过 AM 获得的 PM 的应用开辟了领域。

期刊介绍： -Publishes original research on physical, chemical, and biological aspects of transport in porous media- Papers on porous media research may originate in various areas of physics, chemistry, biology, natural or materials science, and engineering (chemical, civil, agricultural, petroleum, environmental, electrical, and mechanical engineering)- Emphasizes theory, (numerical) modelling, laboratory work, and non-routine applications- Publishes work of a fundamental nature, of interest to a wide readership, that provides novel insight into porous media processes- Expanded in 2007 from 12 to 15 issues per year. Transport in Porous Media publishes original research on physical and chemical aspects of transport phenomena in rigid and deformable porous media. These phenomena, occurring in single and multiphase flow in porous domains, can be governed by extensive quantities such as mass of a fluid phase, mass of component of a phase, momentum, or energy. Moreover, porous medium deformations can be induced by the transport phenomena, by chemical and electro-chemical activities such as swelling, or by external loading through forces and displacements. These porous media phenomena may be studied by researchers from various areas of physics, chemistry, biology, natural or materials science, and engineering (chemical, civil, agricultural, petroleum, environmental, electrical, and mechanical engineering).
