Professor Martin Dunn, Associate Dean and Co-Director of SUTD DManD Research, said:
“In this direction, we focus on three main themes. One is additive manufacturing using multiple materials, especially soft-body materials, to create multifunctional components, parts and products. The second is 3D nanofabrication. The third is The topic is 3D digital textiles and composites.”
Explore design at the voxel level
As the team researches further into material properties and new design approaches, they will explore possibilities beyond predefined digital materials.Utilizing Stratasys J-Series Multi-Material3D printingUsing the on-board GrabCAD Voxel Print™ utility to create products, DManD researchers can precisely manipulate materials and structures point-by-point in space, down to the voxel or voxel level.
voxel-level controlled3D printingTechnology allows us to create microstructures and macroscopic products at unprecedented scales and resolutions. This technology really pushes us to develop new tools that enable people to design with this emerging manufacturing capability.

With GrabCAD Voxel Print, DManD researchers can create entirely new digital materials to meet the specific functional or aesthetic needs of each specialized research project.
Voxel-level control has really changed the way we think about design, now we can scan texture effects directly from the environment and create textures and microstructures from those images. At the same time, various properties including tactile, acoustic, structural wrinkling and thermal properties can also be observed, enabling rapid prototyping of multiple design options.

Researchers can build their own computational analysis and design tools, model layer slicers, and control voxel-level attributes, resulting in bitmap or PNG files. GrabCAD Voxel Print is sliced digital data with3D printerCommunication tools between the generated 3D models possess specific properties that cannot be achieved by other methods.
Multiscale Structural and Materials Design
DManD researchers have used this new method to create an interlocking table for studying the structural behavior of traditional joinery systems. Making interlocking tables was challenging, so Sawako Kaijima and his team of researchers designed a custom slicer to dispense material layer by layer, using GrabCAD Voxel Print to 3D print the joinery system on a Stratasys J-series printer.
“With selective material deposition, we can design and fabricate objects with heterogeneous properties that have superior functional properties compared to objects composed of a homogeneous distribution of materials,” Patel said.
Using a custom slicer and GrabCAD Voxel Print, the researchers 3D printed an interlocking table with gradient properties of VeroClear™, Vero PureWhite™ and TangoPlus™.
“This project is a reflection of the future of design work, where designers will not only create geometric structures, but also design materials on a micro scale for better function and appearance,” says Dunn.
DManD researchers also fabricated multi-material soft lattice structures that can withstand large nonlinear deformations. Soft lattices contain curved components with spatially varying thickness and material that can form free-form geometries. Using another custom slicer to control the material’s hardness and behavior, the researchers can also create the precise soft lattice structures needed for better performance and design.
