Positioning
You can change the position of objects on the build tray—even if they were
inserted with the
Orient Automatically
option. Tools for changing the
position of objects are presented in "Manipulating Objects on the Tray" on
page 5-35.
The orientation of models on the build tray affects how quickly and efficiently
they will be produced by the printer, where and how much Support material
is used, and whether or not model parts will have a glossy finish. Therefore,
you should consider a variety of factors when deciding how to place models
on the build tray, using the following positioning rules.
X-Y-Z Rule
This rule considers a model's outer dimensions.
➢
Since the print heads move back and forth along the X-axis, the printing
time along this axis is relatively short, compared to printing time along the
Y-axis and Z-axis. From this point of view, it is advisable to place the
object's
largest
dimension along the X-axis.
➢
Any surfaces that come into contact with Support materials become matte.
➢
Since models are built up, on the Z-axis, in 16- or 30-micron layers
(according to the printing mode), it is very time-consuming to print a tall
object. From this point of view, it is advisable to place the object's
smallest
dimension along the Z-axis.
➢
Since the print heads measure about 2 inches (5 centimeters) on the
Y-axis, models measuring less than this (on the Y-axis) are printed in one
pass. From this point of view, it is advisable to place the object's
intermediate
dimension along the Y-axis.
