Anisotropic DMs
In many macrostructures, a basic repeating unit cell exists.
A unit cell is the smallest unit that can be cropped without changing the structure.
A single pattern can usually be created by several different unit cells.

Anisotropic DMs
Even with the same concentration of 50%:50%, these materials diagrams behave
differently due to custom microstructures.

Voxel Print
Voxel Print is a Stratasys R&D interface that:
17
•
Reads BMP files directly into an assembly
map, and enables their 3D printing
•
Grants the user control over material deposition
and the printing sequence on a voxel level
•
Enables creation of:
• New structures
• Complex Digital Materials
• More advanced applications and
modifications at model-volume size
levels
