What role does CAD software play in additive manufacturing?

CAD software plays a crucial role in additive manufacturing by facilitating the creation of digital models that are essential for 3D printing. The primary function of CAD, or Computer-Aided Design, is to allow designers and engineers to create precise and detailed 3D models of objects. These models can then be converted into a format compatible with 3D printers, typically a file type like STL (Stereolithography) or OBJ.

The benefits of using CAD software in this context are significant. It enables users to visualize and modify designs before production, ensuring that the dimensions, geometries, and features of the final printed object are accurate and meet the intended specifications. Moreover, CAD software often includes tools for simulating real-world conditions, helping to predict potential issues and optimize the part geometry for performance and manufacturability.

Given the nature of additive manufacturing, where layers of material are added to build up parts, having a 3D model that precisely represents the desired final product is critical. This level of detail and accuracy is not achievable with 2D models or by merely editing scanned images, emphasizing the specific role of CAD in preparing designs for 3D printing rather than managing hardware or serving other secondary purposes.
