Abstract

The article presents the results of work on testing the possibility of using modern and affordable additive technologies based on a photopolymer printer for the manufacture of prototypes of microfluidic devices suitable for solving problems in the oil and gas industry. Two methods for creating microfluidic devices using additive technologies have been studied. The first one is the production of a master mold for subsequent casting of PDMS in it, the second is the production of a microfluidic chip with fully three-dimensional channels. A technique has been developed for creating a master mold with channels of the required geometry for pouring PDMS from a photocurable polymer using stereolithographic printing. This technique was successfully tested for the production of a microfluidic chip with channels with a minimum width of 100 μm. A microfluidic chip with a three-dimensional channel structure was designed and fabricated. It was shown that by printing a master mold for subsequent casting of PDMS in it, it is possible to produce microfluidic chips with a channel width of 100 μm and a height of 50 μm. Such devices can find their application in modeling processes of oil displacement from solid rocks
