4D printing of active structures with spatially variable materials
The image shows a multi-material 3D printed T-Rex when activated inside a hot water bath and actively deforming into its target shape.
The image illustrates the design, simulation, and fabrication process using multi-material 3D printing technology. Principle stress streamlines, indicated in back, provides both expressive quality and structural reinforcement to the final design.
