Multi-material printing

Definition

Multi-material printing refers to the 3D printing process that involves using two or more different materials to create a single object or component. This technique enables designers and engineers to produce complex geometries with varying properties, such as strength, flexibility, and color, all within one print. By leveraging multiple materials, it allows for innovations in product design, functional prototypes, and customized items that would be impossible with single-material methods.
