Brackets and mounts in conventional manufacturing for individual and small-series production do not achieve their maximum functional and economic efficiency. To increase functionality and improve economic viability in individualized structural component design, a method of press molding composites with short cut fibers in a polymer matrix is introduced, using a direct 3D printing method for the inner part of the hybrid mold. Molds made by the FDM 3D printing method offer a low cost of iterating solutions during the individualization process by allowing the quick change of the molded part geometry. Traditional methods of structural components manufacturing, like that of brackets and mounts, bring significantly increased production costs by increasing the complexity of its surfaces including the adding of secondary bracket features. Composite moldings can, however, form very complex external surfaces without additional cost. This paper describes all widely used additive technologies, their applications, advantages, and disadvantages. The loads on the assembly are defined, and the expected mechanical properties of the composite are computationally determined. The load on a conventional CNC-machined aluminum mount is simulated and compared to a composite molding that contains built-in electronics for encoders. The process of creating a model of such a mold and its molding procedure are described. A conclusion is drawn about the obtained results of the model construction and its limitations.
