Changing the Printing Material
Before producing models using a different type of printing material than is
currently installed, run the Material Replacement wizard to flush the print block
and feed tubes.
Before running the wizard, empty the waste container. A full waste container
can cause the wizard to cancel or freeze.
After using the wizard to change the Support material and certain Model
materials, Head Optimization is required before printing models.
You should carefully plan printing models with different materials to avoid
unnecessary waste of the materials currently loaded. The amount of material
flushed depends on the flushing cycle chosen and if you are replacing one or
more cartridges.
The Material Replacement wizard suggests the best slot locations for placing
different material cartridges, based on the materials currently in the system.
This ensures minimum flushing of materials currently loaded.
Note:
When performing manual material replacement, certain replacement
options are blocked to protect the system. In these cases, follow the
recommendations of the Material Replacement wizard for best replacement
options.
To replace the printing material with the wizard:
1. Start the Material Replacement wizard from the
Options
menu.
