    In an attempt to increase resource efficiency and reduce carbon emissions, the development of lightweight designs in structural applications is essential. In addition, the lightweight structures ... often follow complex topologically optimized designs which are more suitable for the application of additive, in contrast to conventional manufacturing techniques. Within the additive manufacturing (AM) process, constituents may be combined to design and produce durable and lightweight materials with predefined mechanical, electrical, and thermal properties, while also accounting for their sustainability and recyclability. Regretfully, due to the lack of research in material behavior, the AM technology implementation in engineering applications is still limited in comparison to traditional manufacturing methods. While the potential of additively manufactured continuous fiber composites has already been recognized in the scientific community, constitutive modeling and damage resistance are seldom reported. Since fiber-reinforced composite structures are rarely designed as unidirectional (UD), this study is focused on numerical analysis of failure for multi-directionally reinforced composite laminates loaded in a uniaxial direction. Specimens are modeled and evaluated using a progressive damage model, proposing guidelines for safer design and application.
