Fusion 360 is an excellent choice for creating CAD models for 3D printing. It allows you to create not only “prismatic” models such as gears or brackets, but it also allows you create more “organic” models using T-Splines, including characters, plants, and vehicles. You can use Fusion 360 to create and then edit your objects for 3D printing. Bring in models from other software and make modifications, such as de-featuring them by removing small features or blends. Fusion 360 can export as an OBJ or STL file format that is read by most 3D printing software. It also has the ability to print directly to your 3D printer. In addition, Fusion 360 even allows you to edit mesh or STL data that is brought in from a laser-scan or other source. Before printing, you can reduce or increase the surface count, edit out features, fill holes, etc.
