What a pixel is to 2D printing, a voxel is to 3D printing. So you can think of a pixel in 2D printing and then make it 3 dimensional. In this image, the box is one voxel. A 3D-printed part is made of millions of these voxels.
With Multi Jet Fusion, we can choose the color, density, or material at the voxel level. Able to print parts that are part rigid and part bendable. In theory, we could make every voxel a different color.
