What application uses an AM part as a model to help design parts for end-use and other applications?

The application that uses an additive manufacturing (AM) part as a model to help design parts for end-use and other applications is the prototype applications. Prototyping is a crucial step in the design and development process, allowing engineers and designers to create a tangible representation of their concepts. By using AM, they can quickly and cost-effectively produce prototypes that accurately reflect the final product's dimensions, materials, and functionality.

This process facilitates testing and evaluation, enabling designers to make necessary adjustments before moving to production. The iterative nature of prototyping with AM allows for rapid refinement, which enhances the overall design process. In contrast, other applications like sculpture, production planning, or quality control do not primarily focus on creating models for design improvement, but rather serve entirely different functions in the AM landscape.
