3 Materials
Both sections of each print head are loaded with the same material.
Figure 4-13 Three materials loaded in the print heads
Up to three Model materials are available, with high-speed printing.
5. In the
Required materials
section of the wizard screen, select one or more
replacement materials cartridges.
6. For Model materials, select
Both
if you need to load two replacement
cartridges.
Loading one replacement cartridge is more economical because it potentially
requires less flushing of material currently in the system. However, when one
cartridge is not sufficient, loading two cartridges enables continuous printing
until the print job is completed. When one cartridge empties and the other one
is being used, you can replace the empty cartridge with a new one.
7. For Support material, select the number of cartridges to replace (2, 3, or 4).
Note:
At least two Support material cartridges are required.
8. If the color or mechanical properties of the first printed models are
unimportant, you can change the Model materials without flushing out the
current materials. To do so, continue with "Changing Model Materials Without
Flushing" on page 4-19.
