Abstract: Three-dimensional printing on a membrane of a filtration device is described herein. Forming the filtration device involves receiving a membrane comprising a porous material, depositing an ink into pores of the porous material, causing the ink to solidify, and continuously building three-dimensional printed structures via micro-stereolithographic three-dimensional printing. Solidifying the ink causes the ink to bond with the membrane.

Abstract: Methods of preparing a mineral-coated rock micromodel can include 3D-printing a transparent porous micromodel with photo-curable polymer, seeding a thin layer of mineral nanoparticles in the network of pores inside the micromodel, and subsequently growing a mineral layer on the thin layer of mineral nanoparticles. The thin layer of mineral nanoparticles can be introduced by injecting a suspension containing the mineral nanoparticles through the microporous polymer micromodel, and the mineral layer can be grown in-situ on the thin layer of mineral nanoparticles in the network of pores by injecting an ion-rich solution configured to crystallize from solution in response to contacting the mineral nanoparticles.
