基于树脂的三维（3D）打印对于包括复制地质多孔介质样品的许多应用是流行的。这项研究是第一次探索基于树脂的反应性多孔介质3D打印。在这里，砂岩复制品的数字光投影（DLP）3D打印使用与不同量的方解石混合的光敏树脂进行。使用X射线微计算机断层扫描（μCT）对打印样品进行3D成像。打印的样品孔隙率一致，接近原始补片孔隙率。方解石体积分数通常与树脂混合物中的方解石含量一致。方解石的可及表面积是相似的公布值为真实的砂岩和方解石溶解观察到在酸性批实验，其表面反应性的证据。因此，DLP印刷有希望用于制造反应性多孔介质样品。
Resin based three-dimensional (3D) printing is popular for many applications including replicating geologic porous media samples. This study is the first to explore resin-based 3D printing of reactive porous media. Here, digital light projection (DLP) 3D printing of sandstone replicates was performed using photosensitive resin mixed with calcite of varying amounts. Printed samples were imaged in 3D using X-ray micro computed tomography (μCT). Printed sample porosities are consistent and close to the original mesh porosity. Calcite volume fractions are generally in agreement with the calcite content in the resin mixture. Calcite accessible surface areas are similar to published values for real sandstones and calcite dissolution was observed in acidic batch experiments, evidence of its surface reactivity. DLP printing is thereby promising for fabricating reactive porous media samples.
