6.3.1 

Inspecting the sifter mesh

Clumps of powder can accumulate in the sifter’s mesh screen below the grate, eventually 
preventing reclaimed powder from passing through to be collected.

To inspect the sifter mesh:

1.  If the sifter is on, tap 

Sift

 on the touchscreen or push the 

Sift

 button on the control panel 

to turn off the sifter.

2.  Lift the white grate up using the depression in the back-right corner of the workspace and 

set it aside.

3.  Turn on the vacuum by pushing the 

Vac

 button on the control panel or by tapping the 

vacuum hose icon on the touchscreen.

4.  Vacuum any debris, clumps, or loose powder from the sifter mesh. Be very careful not to 

damage the sifter mesh with the vacuum or vacuum hose.

5.  Turn off the vacuum by pushing the 

Vac

 button on the control panel or by tapping the 

vacuum hose icon on the touchscreen.

6.  Examine the sifter mesh for signs of clogging or stuck powder. If the sifter mesh needs 

additional cleaning, follow the instructions in section

 6.4.4 Cleaning the sifter mesh

.

7.  Reinsert the grate.

6.4.4

Do not use compressed air or an air gun to clean the Fuse Sift’s vent, surface grate, 
build chamber enclosure, or any other component. Mobilizing loose powder increases 
the risk of unintentional inhalation or ingestion.

6.4.1 

Adding fresh powder to the Fuse Sift

The Fuse Sift dispenses a mix of fresh and used powder into powder cartridges. Add fresh 
powder to the Fuse Sift whenever the fresh powder hopper runs low.
