The topological optimization is a technique that aims to vary the geometric shape of a three-dimensional object in order to meet requirements on the positioning of constraints and application of forces and to minimize the use of material with the aim of obtaining a lightweight structure with competitive mechanical characteristics.
All this is performed by means of a FEM analysis (finite element analysis). This study allows to study complex physical phenomena identifying problems before the realization of a prototype.
In previous years, before the technology of Additive Manufacturing took hold, the study of geometry and design assumed a marginal role compared to the design of the component under consideration. This was because design software had great limitations.
The future of Additive Manufacturing and its derived technologies have changed the cards on the table and with the topological optimization based on loads and constraints applied, it is possible to generate a model in an automatic way, increasing performance.
Topological optimization: the new techniques
The new design software allows a strong reduction in the weight of components by completely eliminating the superfluous.
Light-weighting a component not only reduces manufacturing costs by using less raw material, but also provides advantages related to ease of transport.
3D Metal designers have become very familiar with this software over the years and can completely redesign a component.
With this method of execution, you can
- Reduce production time by using less material than a non-optimized component.
- Obtain particular geometries and aesthetics not obtainable with other technologies.
- Have an advantage in economic terms.
The topological optimization has its maximum expression with the Additive Manufacturing technology because by reducing the weight it is possible to obtain shapes that are difficult to obtain with other methods. In this way it is possible to realize a particular as you really want it.
