What AM tool is used to create the 3D digital models to be produced by the machine?

The correct choice is Computer-aided design (CAD) software because it is specifically designed for creating precise, detailed 3D digital models that serve as blueprints for additive manufacturing processes. CAD software provides designers with a range of tools to visualize and manipulate the dimensions, shapes, and features of the model, allowing for the creation of complex geometries that can be directly translated into 3D printable files.

In the context of additive manufacturing, CAD software enables designers to incorporate design elements that optimize the model for printing, such as considering support structures and material properties. This software also allows for easy modifications and iterations during the design process, ensuring that the end product meets the desired specifications before moving on to the manufacturing stage.

While 3D scanning software is used for digitizing physical objects into digital 3D models, it is not primarily for creating new models from scratch. Virtual reality tools enhance the visualization and interaction with 3D models but do not typically create the models themselves. Simulation software analyzes how a part will perform in real-world conditions but does not generate the initial design model required for 3D printing. Thus, CAD software is the most appropriate tool for creating the models intended for additive manufacturing.
