Additive production of composites is a relatively new technology, the development of which currently allows the printing of long-fibre reinforced components. The rapid development technology necessarily requires finding a suitable application. Mechanical tests are performed to determine the material characteristics and behaviour of the material under different types of loading for these reasons. Several studies have been published dealing with tensile and bending tests of additive produced composites. The authors have performed a Charpy impact test on the same materials in the past. The influence of printing parameters (infill type, reinforcement type, lamina thickness, infill orientation) and the orientation of the load against the position of the laminas in the composite on the mechanical properties (achieved values of impact toughness) were identified by experimental measurements. The first phase was performed on un-notched specimens. In the second phase, further research and experimental measurements were performed on notched specimens.The aim of the article was to assess the influence of the notch on the mechanical properties of composite materials produced on the basis of 3D printing. The results show the dependence of the laminate layering on the direction of loading. The impact toughness decreased by 35 % on notched specimens in the case of perpendicular direction of loading to laminas layering. In the case of direct loading to laminas layering, notched specimens achieved higher impact toughness than specimens without notch.
