Researchers from both the US and China are taking digital fabrication and texture in materials to the next level, releasing the findings of their study in the recently published ‘4D Texture: A Shape-Changing Fabrication Method for 3D Surfaces with Texture.’
4D printing is growing as an area of interest for many researchers, but like 3D printing—and even more so—there is still enormously uncharted territory. Users are able to move beyond the constraints of 3D printing to meet pressing needs for more complex projects like creating new metastructures, surfaces, and new materials and techniques. 4D printing offers more to users innovating beyond the 3D, seeking to fabricate more complex geometries too.
In this study, the authors introduce a new design approach called 4DTexture which they describe as a ‘holistic computational design and fabrication method, leveraging the state-of-the-art 4D printing process to make 3D surfaces with texture.’
While the benefits of 3D printing are and continue to be vast for industrial users, 4D printing opens up new areas for fabrication that usually cannot be explored through conventional technology either. The new technique created in this study allows for actuators to be made with vertical texture structures—later to be turned into more complicated forms. The system runs on Rhino with Grasshopper, comprised of the following for preview and customization:
- Texture element
- Tendency and transformation type
Experiments were performed on textured structures as the researchers built up a ‘library’ consisting of shapes like hemispheres, pyramids, and hemicylinders. The program offers tools so that parameters can be customized; for example, designers can use offered 4D morphing mechanisms from previous projects or modify the settings if needed. Once the actuator shapes are set, textures can be arranged. Height and size can be chosen, and users can also move textures.
PLA was used with a MakerBot Replicator 2X as the researchers printed sample textures using the defaults for the hardware, producing self-rising, self-coiling, and self-bending objects.
“The transformation mechanism can be controlled by the printing direction, which has been embedded into our system to simulate the behavior,” stated the researchers.
Just as 3D printing has allowed for a variety of different forays into fashion, 4D printing has too, bringing all the benefits of materials that can morph and shift as needed. In this study, the researchers fabricated fashion accessories, a modular toy, a haptic handle, and 3D fasteners.
“We hope such a system can expand the design opportunity of 4D printing technology with a hobbyist FDM printer,” concluded the researchers. “In the future, we plan to implement a systematic material experiment for improving transformation accuracy and fine-tune the parametric setting with Grasshopper to make the design tool more user-friendly. We also found that the texture structure can serve as a constrained layer which needs further investigation.”
