Shape, stress, loads, mass are the main things to consider before starting to print. The topology optimization is one of the calculation methods that help you to obtain optimized CAD models before uploading it to our 3D printing service.<\/div>\n<h2 class=\"jssocials-share jssocials-share-linkedin\">What is Topology Optimization?<\/h2>\n<\/div>\n<\/div>\n<p>It is a technique that optimizes the geometry of an object thanks to a mathematical method, within a given space and with given loads and constraints. The goal is to maximize the performance of a part by reducing its mass.<\/p>\n<div id=\"attachment_21087\" class=\"wp-caption aligncenter\"><\/div>\n<figure id=\"attachment_102632\" aria-describedby=\"caption-attachment-102632\" style=\"width: 504px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-102632\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/09\/Topology-Optimization-process.jpg\" alt=\"\" width=\"504\" height=\"580\" \/><figcaption id=\"caption-attachment-102632\" class=\"wp-caption-text\">The process of topology optimization<\/figcaption><\/figure>\n<p>Designers and engineers use topology optimization to conceive parts but the parts optimized with this technique are often difficult to manufacture through traditional manufacturing methods.<\/p>\n<h2 class=\"sub-heading\">Topology Optimization with Additive Manufacturing<\/h2>\n<p>The field where topology optimization helps the most is surely additive manufacturing. With 3D printing, it is known that the less material is used to manufacture the part, the better it is.<\/p>\n<p>Indeed, a part that uses less raw material to be produced means that it will be lighter and cheaper.<\/p>\n<p>Topology optimization has the capacity to improve 3D models with constrained parameters to enhance the shape and reduce the amount of material used.<\/p>\n<p>Additive manufacturing doesn\u2019t encounter the same limits as traditional manufacturing methods and can go further with shape optimization thanks to the ability of 3D printing to print complex parts.<\/p>\n<h2 class=\"sub-heading\">Improving the shape of a CAD model<\/h2>\n<p>To optimize the shape of a model, you can use the dedicated tools of some software:<\/p>\n<ul class=\"list\">\n<li><strong>Fusion 360<\/strong><\/li>\n<li><strong>Inspire<\/strong><\/li>\n<li><strong>Cura<\/strong><\/li>\n<\/ul>\n<p>And much other software. You can also run a python script that optimizes the topology.<\/p>\n<h2 class=\"sub-heading\">Shape Optimization for 3D Printing with Fusion360<\/h2>\n<p>Autodesk Fusion 360 has a very interesting shape optimization tool.
