What is the primary role of CAD modeling in additive manufacturing?

The primary role of CAD modeling in additive manufacturing is to allow for precise design and the modification of complex geometries. CAD software plays a crucial role in the additive manufacturing process by enabling engineers and designers to create highly detailed and intricate designs that can be directly translated into 3D printed parts.

This capability is essential because additive manufacturing, unlike traditional subtractive manufacturing processes, can produce geometries that are not feasible with conventional methods. For example, CAD modeling allows for the design of hollow structures, complex lattice designs, and intricate surface details that can optimize the functionality and performance of a part while reducing material usage.

Moreover, CAD tools make it easier to make adjustments and optimizations before the actual printing begins, ensuring that the designs meet the intended specifications and performance requirements. This adaptability and precision in design are what empower additive manufacturing to take on innovative projects and create customized parts tailored to specific applications.
