To clean overflow chutes and screens
The chutes below the overflow holes at the right
and left ends of the powder bed have screens to
catch chunks of agglomerated powder and
broken part pieces. The screens prevent these
chunks from clogging the SLS system’s powder
transporters and tubes.
L
If you run out of powder unexpectedly, your
overflow chute(s) and/or screen(s) might be
clogged.
Periodically check and clean the overflow chutes
and screens. The steps are the same for the right
or left side overflow chutes.
1
Exit Sinter, then wait for the SLS system to
cool down.
2
Open the (left or right) side access doors on
the SLS system enclosure. See
SLS System
Features on page 182 to locate the access
doors.
3
Locate the hinged, sealed cleanout panel on
the outer wall of the overflow chute.
4
Use a flathead screwdriver to loosen the two
captive screws on the cleanout panel.
5
Before you open the panel, put a garbage
under it to catch any powder that falls out.
6
Lift out the screen and clean it off, then put it
back in.
7
Close the panel, then press lightly as you
retighten the two screws. (Pressing in helps
seal the panel.)
8
Check and clean the other overflow chute.
9
Restart Sinter and continue.
