Objet30 User Guide
In the printer interface, the printer mode changes from Idle to Pre-print, as the
printer's components prepare themselves for production:
• The print block is heated.
• If more than 48 hours have passed since the last print job, the printing
• The UV lamp is powered and it warms up.
When printing begins, the print manager program sends a number of slices to
the printer-control application. This fills the buffer between the print manager
and the printer to ensure continuous printing. As each slice is printed, as a
layer of the models on the build tray, another slice is sent to the printer.
Depending on the size of the model(s) to be produced, printing can take
between several hours to several days. As long as there is enough Model and
Support material in the supply cartridges, printing proceeds automatically until
the job is finished.
During printing, the server computer must remain on and it must
communicate with the Objet30 printer. Do not log-off Windows until printing
is finished.
The Objet30 printer uses one Model-material cartridge and one Support-
material cartridge to produce models. When four cartridges are loaded in the
printer, two of them are reserve, or standby, cartridges. By default, the printer
first uses the cartridges with the least material in them. The printer interface
indicates which are being used (see "Printer Interface Color Key" on the next
page).
When the weight of a cartridge drops below 200 grams, the remaining material
displayed on the printer interface is red.

materials in the print heads are flushed and replaced, to ensure quality
printing. (This step adds 7 to 14 minutes to the Pre-print cycle, and it is
displayed on the printer interface.)
