This session focuses on the design phase of 3D printing using Fusion 360. Participants will be introduced to the Fusion 360 interface, core design concepts, and the difference between sketching and 3D modeling. Through hands-on practice, they will learn essential sketch tools, constraints, and dimensions, followed by basic 3D features like extrude, fillet, and chamfer. The session also introduces slicing software, explaining print settings such as infill, speed, supports, and G-code generation to prepare models for printing.
