BASIC JOB BUILD TASKS

BEFORE A JOB BUILD

To build a job, you must send the job file to the system from the Insight application installed on your workstation.
Jobs are sent in a CMB format and placed in the job queue (stored on the system hard drive). The header of the
CMB file contains the processed job's basic information (material type, approximate material amount required
for build, tip size, etc.). This information is used to verify job compatibility with the system setup.
For detail about how the system uses file information see
1. Prepare the system:
A. Power up the system. (Stabilization of the system takes approximately four hours.)
B. Install a new build sheet by doing the following;
Warning: Wear proper safety equipment when handling items inside the oven.
Surfaces in the build chamber can be very hot.
i.
Remove the plastic wrap from both sides of a new build sheet.
Note: Always use a new build sheet when building a job. The build sheet is
intended for one-time use. Do not turn a build sheet over and place it on the
platen. Material residue on the sheet can adhere to the platen or interfere with
the build sheet vacuum.
Using build sheets not provided by Stratasys may impact part quality and system
reliability.
ABS, ASA and PC parts use a clear build sheet.
PPSF parts use an amber-colored build sheet.
Nylon 12 parts use a green tinted build sheet.
ii.
Set the build sheet on the platen.
•
The Fortus 900mc can accommodate two sizes of build sheets. Make sure the build sheet that is
used is centered on the platen.
•
If the oven is hot, the build sheet will curl when placed on the platen. As the build sheet warms up, it
will flatten and adhere to the platen. Some adjustment of the sheet may be necessary to seal it
against the platen. (Turning the platen vacuum off and on will help this final adjustment to a warm
build sheet.)
iii.
Make sure the active model and support canister bays have filament loaded to the head (steady green
LED).
iv.
Make sure the loaded filament match the material requirements of the CMB file. Change material type if
necessary (see
v.
The touchscreen warns if there is a material mis-match.
vi.
Make sure that the tip cleaning brush and tips are clean.
vii.
Empty the purge bucket.
viii.
If using Auto-Cool Down, or if the material type has changed, allow the oven to heat and stabilize for at
least four hours.
