This presentation will present an overview of the state-of-the-art, newly introduced capabilities in the areas lattice structure generation, generative design, CAD reconstruction of generative design results, generation of validation models for performance simulation, and optimization of print orientation. Lattice structures have been used for a long time by nature, now with AM and new CAD and IMT capabilities we can use them in our designs. A pictorial taxonomy of lattice structures such on surface (i.e. iso-grid), 2 ½ D (i.e. honeycomb), 3D beam (i.e. diamond, octet) and 3D shell (i.e. gyroid, diamond, custom) will be presented. Generative design is the automatic process to generate optimum feasible designs from a set of performance requirements and design rules. The generated organic designs can be printed using metal additive manufacturing. The generative fesign processes of the modern tools will be presented and demonstrated with three examples from the aerospace industry. Over the last three decades, the main bottleneck in the optimization process is the conversion of generative design results back to a CAD. This is not an issue anymore; several tools offer that capability. A simple technique that converts the tessellated generative design results to a B-rep sub-divisional surface models will be demonstrated. Another challenge that we recently have overcome is how to simulate the structural or thermal performance of these complex geometries. A new class of real-time simulation tools enable us to simulate intricate lattice structures. A live example will demonstrate the real-time simulation capabilities.
