The application of 3D printing in conventional printing technology was studied. Two methods of using of 3D prints in function of 2D printing were considered. Physical and mechanical characteristics of printed 3D material were determined in order to verify the use of 3D prints in conventional flexography printing process. 3D prints can be used as flexographic printing plate directly and as a negative matrix for conventional photopolymer flexographic printing plate production. Current material 3D prints are brittle and porous; therefore the finishing is required before further use. Liquid epoxy resin was considered as an appropriate agent as well as some other infiltrates, such as cyanoacrylate and polyurethane infiltrants. It is important that the applied infiltrant penetrates completely into the 3D print without any influence to its dimensions. The digital test form of the flexographic printing plate is required for the 3D printing. It can be constructed either by computer program or by scanning. 3D scanner is appropriate if the conventional flexographic printing plate exists and the 3D technology is used to produce the copy. The attempt of producing the 3D digital test form of the flexographic printing plate by means of computer programming was done.
