The following parameters are available to set in the Add Powder Layer dialog:
NOTE: You cannot close the Add Powder Layer dialog box while the printer is adding layers .
Add Powder Layer Parameters
PARAMETER
RANGE
DEFAULT
DEFINITION
Powder Feed amount 0 to 10 rev .
0 .2 rev .
The number of revolutions the powder dispenser
makes when dispensing powder on top of the
roller . (The powder dispenser is at the bottom of
the feed hopper .) Typical setting is 0 .2 rev .
Layer Thickness
0 .1 mm (0mm available for
Add Powder Layer)
0 .1 mm
The distance that the part piston lowers each
layer .
Layer Cycle Count
1 and 32,000
1
The number of consecutive powder layers to be
added .
Roller: Rotation Ratio 0 to 15
11
The ratio of the roller’s counter-rotation angular
velocity to its (linear traverse) speed . The larger
the ratio, the faster the counter-rotations .
Roller Traverse Speed 76 and 305 mm per second
(3 and 12 inches per second)
203
Specifies the speed at which you want the roller
to travel .
Calibrating the IR Sensor
The printer will recalibrate the IR sensor dynamically during a build . This calibration is a quick process which occurs multiple times
during a print to compensate for sensor drift and changing environmental conditions within the machine .
NOTE: You must perform an initial offline IR calibration to enable automatic, real-time recalibration during the print. If
recalibration requires too great an adjustment, a message pops up advising you to perform offline calibration again
when the print completes .
NOTE: Once you perform a manual IR calibration, the settings are saved in the system . A manual IR calibration does
not need to be performed before each print .
If you want the printer to do real-time IR sensor recalibration during the print, perform a manual IR calibration before you start the print
as described below .
NOTE: You can opt to have the printer simply verify IR sensor readings rather than recalibrate. Click the Verification
Only checkbox in the IR Cal window to choose this option .
To Perform Manual IR Calibration
1 . Put the system in
Manual Operations
mode .
2 . Click the
IR Cal
button .
3 . The
Manual IR Sensor Calibration
dialog box appears .
4 . Click the
Start
button on the dialog box . The calibration will last approximately 10 minutes .
NOTE: During the calibration, an Abort button appears; click it if you need to stop the calibration process for any
reason .
NOTE: If the part bed or the blackbody is above 60 °C, the software waits until they cool to actually start the offline
calibration .
NOTE: If the IR sensor core temperature is below 77 °C, the offline IR Calibration will wait until 77 °C has been
reached, and then an additional 5 minutes for the core to stabilize .
