Fast and Accurate Additive Manufacturability Analysis

This paper focuses on the design optimization of complex 3D composites structures made by additive manufacturing processes. There are commercial CAD-CAM software solutions for detailed offline path programming, but there is a growing need for innovative tools and methodologies for doing trade oil studies very early at design stage. A new innovative solution has been developed on top of the CATFIBER■ software,allowing both designers and stress engineers to quickly analyze complex double-curved geometries. It also includes a variable stiffness approach with tow-steering, and structural analysis of the manufacturing defects using Digimat■ software.
