Cross-sectional Structural Analysis for 3D Printing Optimization (4:00 min.)

Abstract

We propose a novel cross-sectional structural analysis technique that efficiently detects critical stress inside a 3D object. We slice the object into cross-sections and compute stress based on bending momentum equilibrium. Unlike traditional approaches based on finite element methods, our method doesn’t require a volumetric mesh or solution of linear systems, enabling interactive analysis speed. Based on the stress analysis, the orientation of an object is optimized to increase mechnanical strength when manufactured with 3D printing.

    Meshmixer is a prototype design tool based on high-resolution dynamic triangle meshes. We are exploring the new capabilities of this surface representation for interactive design and fabrication, in the context of a practical system we release to the public.
