Selecting support style:
Support material is used to support the model during the build process. It is
removed when the part is complete. Support styles will affect the support
strength and build time of the print. SMART support is the default support
setting as it uses the least amount of support material and allows for faster
build times.
• Basic - May be used for most parts. Basic support uses a consistent
spacing between support toolpaths.
• SMART - minimizes the amount of support material used, reduces
the build time, and improves support removal for many parts.
SMART supports use a wide spacing between toolpath rasters and
change the shape of the support region. As the supports descend
from the underside of the part feature to the base of the supports,
the support region shrinks and transforms to a simpler shape to
reduce the amount of material used and the build time. SMART sup-
ports are suitable for all parts, especially those with large support
regions.
• Surround - The entire model is surrounded by support material.
Typically used for tall, thin models.
Selecting the scale of your STL file:
Before you process a part for printing, you can change the size of the part
within the build envelope. Every part has a pre-defined size within the STL
file. After you have opened the file you can change the size of the part
produced from the STL file by changing the scale. The scale always relates to
the original STL file size definition.
For example: a cube that is defined as 2 X 2 X 2 can be built to be 4 X 4 X
4 by simply changing the scale to 2.0. If after changing the scale to 2.0, you
decide that a size of 3 X 3 X 3 would be preferred, change the scale to 1.5 -
the scale relates to the original size of 2.0, NOT the resulting 4.0 from the
first scale change.
Click within the scale input box to type a scale of your choice.
Selecting the orientation of your STL file:
The Orientation tab has an expanded preview window. It provides options
for viewing a part, measuring a part, orienting a part, processing a part and
viewing the layers of a part. How a part is oriented in the preview window
will determine how the part is oriented when it prints.
Orientation impacts build speed, part strength, surface finish and material
consumption. Orientation can also affect the ability of HP Designjet 3D
Software Solution to repair any problems with the STL file.
You can choose to auto orient your part, which allows HP Designjet 3D
Software Solution to determine the best orientation for the part for the fastest
build time and least material usage, or you can manually change the
orientation of your part.
