RUN SINTER APPLICATION
1 . Start the Sinter application: from the Windows task bar; choose
Start > Programs > SLS System > Sinter
, then . . .
•
The Sinter application window opens .
•
The RealMonitor utility starts, appearing as a
RealMonitor
button in the Windows taskbar . Sinter icons will remain grayed-out
until the DSP is initialized . (Sinter uses DSP to control SLS system heaters and motion, and to communicate with the laser
scanning system .)
2 . When you see the DSP button in the taskbar, the Sinter application is ready to start a print . However, you must prepare the
chamber before printing the parts .
BREAKING OUT PARTS
Once the print job has finished, the part cake will need to be cooled and transported to the MQC System for breakout.
To cool down the print cake and remove the print cake from the print chamber, refer to the section,
“Removing the Print Cake from
the Print Chamber” on page 44
.
For instructions on breaking out the parts from the print cake at the MQC System, refer to the section,
“Breaking Out Parts” on page
47
.
For post-processing parts, refer to the
Material Guide
for your specific material.
Preparing the Print Chamber
The following steps are a suggested guideline for preparing the system to print parts .
1 . Check to see if the MQC is in Fully Cycle mode and that there is enough powder in the blended bin for the print . Refer to the
section,
“Set the MQC System to Full Cycle Mode” on page 32
.
2 . Close and latch the inner print chamber door and close the outer door . All interlocks must be engaged to move the piston or roller .
3 . If the piston is not homed, go to
Sinter > ManOps > Piston Control
and select
Home Piston
.
4 . If the roller has not been homed, press the
Roller
button on the toolbar, then press the
Home Limit
button in the dialog box to
home the roller .
5 . Press the
Inert
button on the toolbar and select the
Enable
toggle option to activate the inerting process .
6 . Press the
Add Powder
button on the toolbar to create level print bed:
•
While the machine is inerting, begin leveling powder . Set the
Layer Thickness
to 0 .0 . Specify the number of cycles, normally
2 at a minimum, in the
Layer Cycle Count
field press the
Add Layer
button to begin leveling .
7 . Once the powder has been leveled, and if the next build has not yet been set-up, open Build Setup, complete the Build Setup, and
close the function . Refer to the section,
“Run Build Setup” on page 34
for detailed instructions .
Running the Build
After the preceding steps have been completed, the printer is ready to print parts .
1 . Verify that the IR Core temperature value is 77 °C . If necessary, run an IR Calibration . Refer to the section,
“Calibrating the IR
Sensor” on page 42
2 . Press the
Exit
button on the toolbar to exit Manual Ops and return to the main Sinter screen .
3 . Select
Build > Start Build
, select the build packet name, and select
Start
.
4 . Once the O
2
level of 5 .5% has been reached, the roller should begin adding powder layers .
