Avoid Support-Material Rule
This rule considers models that have large holes or hollows, open on at
least one side (like a pipe or a container).
It may be advantageous to print a model standing up, so support
material does not fill the hollow, even though printing the model lying
down would be much faster.
Manipulating Objects on the Build Tray
Positioning
Objects on the
Z-Axis
When you use the automatic positioning option to arrange objects on the
build tray (see Automatic Orientation on page 5 26), the objects are
positioned directly on the tray. If you do not insert objects with automatic
positioning, they often appear either above or below the tray.
To position objects directly on the tray:
1. Select the object.
2. From the Object menu, select
Lay On
.
To ensure that objects are always positioned directly on the tray:
1. From the Tools menu, select
Options
, and display the Settings tab.
Figure 5-35: Options dialog box, Settings tab
2. In the Automatic Lay On (Gravity) section, select
Always
.
Other Z-axis options (in the Automatic Lay On section):
•
When under the tray
The display of objects that are below the build
tray is automatically changed so that the object is at tray level.
•
Never
The display of objects that are above or below the build tray is
not changed.
In practice, the Objet system prints all models on the build tray on a one-
millimeter bed of support material. The importance of positioning objects
directly on the build tray with Objet Studio is to correctly display the objects
on the screen.
