5.3.1.2 Saturation
Values
The saturation values determine how much binder is placed on the powder to print the part. The
part is made up of two areas, the shell and the core, as described in Section 1.2,
How It Works
.
Thus, there are two saturation values, one for the shell and core. In general, the shell saturation is
higher than the core saturation. The ZPrint Software will display the recommended values for each
powder type.
1. Plaster Material System
The shell and core saturation values for the plaster material system are generally constant values,
meaning that there is only one value for all geometry types.
2. Starch Material System
The shell and core saturation values for the starch material system depend on part geometry. A
thick walled part will have lower shell saturation than a thin walled part. Core saturation is
dependent on the wall thickness of the part. The thinner the wall thickness the higher the core
saturation; the thicker the wall thickness the lower the core saturation.
3. ZCast Material System
The shell and core saturation values for the ZCast material system are generally constant values,
meaning that there is only one value for all geometry types.
The ZPrint Software will recommend shell and core saturation values based on the part geometry.
These values will work for most parts except the following:
Parts where a large volume will be unsupported when the part is fully depowdered need to
have their saturation values manually set. These parts should be printed with a very low
core saturation value and the highest shell saturation possible without affecting
depowderability (cakiness).

Volume
PLEASE NOTE:
When printing parts that are thinner than 1/8 of an inch (3 mm). Increase
saturation values:
Shell Saturation: 2
Core Saturation: 1
