Additively Manufactured LatticesAdditive manufacturing (AM) enables the production of complex lattice structures that cannot feasibly or economically be manufactured any other way. However, there are complicating factors that engineers are likely to confront when designing fine AM lattice structures: geometric inaccuracy and anisotropic material properties.
Anisotropy of 3D-Printed PolymersMany additively manufactured polymers exhibit anisotropic mechanical properties which must be accounted for by engineers designing with these materials. This case study illustrates the importance of testing additively manufactured polymers at many orientations to identify the range of isotropic behavior as well as the optimal build orientation.
Optimizing Additively Manufactured Parts for Adhesive AssemblyVeryst used topology optimization to design an additively manufactured bracket for adhesive assembly and then used cohesive zone modeling to predict the strength of the bonded joint.
Strength of Additively Manufactured PartsVeryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.
Additive ManufacturingVeryst Engineering helps clients realize high-performance additively manufactured parts. Our strong foundational knowledge in materials science and mechanics coupled with practical expertise in experimental methods and engineering software make us uniquely qualified to solve complex additive manufacturing challenges.
Veryst engineers and scientists offer additional specialized expertise in a wide range of important areas, including the following fields. In each case, we concentrate on meeting client need through the application of fundamental engineering science.
Veryst’s mechanical testing capabilities have been developed over the past decade and are motivated by the need for high quality data to characterize complex polymer behavior. We tailor our test programs based on our deep understanding of polymer and material mechanics and the challenges complex
