Parametric Design

Definition

Parametric design is a process in which the parameters and rules define the shape and function of an object, allowing for a high degree of flexibility and customization in the design. This approach uses algorithms to manipulate design variables, enabling the creation of complex geometries that can be easily modified. This process is particularly important in 3D printing, where precise control over design parameters can significantly impact the performance and aesthetics of printed structures.
