Abstract
The mechanical properties of additively manufactured plastic components, i. e. strength and stiffness, can limit their use as load-bearing structures. In particular, the use of continuous reinforcing fibers can significantly improve the mechanical properties of additively manufactured components and enable the production of load-bearing fiber composite structures. In this context, it seems reasonable to develop the required equipment and process workflows, but also procedures for the load-optimized positioning of fiber paths inside the component and its design. In this paper, the current challenges in the field of technology development of continuous-fiber reinforced 3D printing are highlighted. Possible solutions for the development of a 3D printing system and the generation of necessary toolpaths are presented on the basis of the FIBER-PRINT 3 project. Contents from a subsequent project present a design strategy for a load-optimized positioning of the continuous fiber reinforcement within the component and the implemented calculation of principal stress trajectories as a step towards optimization of the fiber positioning.
