GraMMaCAD – Graded Multi-Material CAD

GraMMaCAD helps engineers enhance CAD models with targeted material gradients, enabling them to efficiently create functionally optimized multi-material components.

Our Solution: Interactive CAD Software for Material Gradients and Multi-Material 3D Printing

GraMMaCAD provides an interactive CAD environment in which material gradients can be defined directly on an existing 3D model. Functionally graded materials—i.e. spatial variations in material properties—can be defined efficiently, including gradients that continuously follow the shape of the component. When the geometry changes, the gradients automatically adapt accordingly.

The software significantly reduces manual effort and enables consistent, reproducible data preparation for multi-material 3D printing processes.

For design and engineering professionals
GraMMaCAD makes it possible to quickly and interactively add functional material gradients to CAD models of components and prepare them for multi-material 3D printing. Gradients can be defined efficiently and reused when the model geometry changes.

For manufacturers of multi-material 3D printers
The software makes the capabilities of printing technologies that can combine or selectively position multiple materials easy for users to access. This allows customers to take advantage of the printer’s unique capabilities more quickly and use them efficiently in their applications, increasing the attractiveness of multi-material 3D printers.

Ceramic and TPU Components

Lithoz GmbH uses the software to develop graded ceramic components for Lithography-based Ceramic Manufacturing (LCM) and to demonstrate the benefits of its technology.

GraMMaCAD is used at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA to create component prototypes with functionally graded structures in connection with voxeljet GmbH’s High Speed Sintering technology.
