8.2 Saturation Values Overview

• In general, the saturation settings for high performance powders are constant for all parts. The

default saturation values, suggested by ZPrint, are designed to successfully print a majority of

parts.

• In general, bulkier parts will print more successfully with a lower saturation setting and delicate

parts will print better with a higher saturation setting.

• Default values are defined in terms of percentage. The recommended saturation values are

always 100%.

• Saturation values may be changed by percentage. When changing any value corresponding to

shell saturation, the relative core saturation is also changed. The saturation values displayed are a

percentage of the recommended saturation value.

• You may manually override the core percentage, if needed.

8.3 Anisotropic Scaling Overview

Anisotropic Scaling is mainly used with zp

14 (Investment Casting) and zp

15e (Elastomeric) powders,

and operates as a simple multiplier. If you have experienced part shrinkage or expansion, it may be the

result of humidity and temperature variations between operating environments. ZPrint sets the default

powder settings for Anisotropic Scaling based on the powder type being used with your printer. These set-

tings tell the printer how much to compensate for these part shrinkage or expansion differences.

NOTE: When Anisotropic Scaling is applied to a part, the physical part increases or decreases in size.

The part rendered in ZPrint changes in appearance when Anisotropic Scaling is applied, but the

dimensional values do not change and remain the same. It may be necessary to rescale and/or justify

the part after applying Anisotropic Scaling.

Anisotropic Scaling values in the Powder Settings dialog are the default settings and cannot be changed.

To apply different a Anisotropic setting to an individual part, select the part and then select Transform >

Anisotropic Scaling and enter new values in the Powder Settings fields. The settings are applied to the

current build only.

To keep the new settings as the default in the Anisotropic Scaling dialog, check the Save as default val-

ues option. The Anisotropic Scaling dialog updates with the new settings.
