Single-material printing: All print heads print models without regard to the
source of the model material. This happens in the following situations:
¾ All print heads are supplied with one model material.
¾ Each pair of print heads is supplied with a different model material, but
models are printed as if they were the same material. The result is an
arbitrary mixture of materials in the printed model.
Digital Material Mode is selected automatically when more than one model
material is assigned to objects on the tray.
