2. Inspect the filter visually; if material deposits are visible, proceed to steps 3–4.
3. Starting from the top and moving from left-to-right, vacuum powder out of the filter pleats.
Note any loose powder that falls down into the work area.
4. Move down and across until the entire filter has been vacuumed and loose powder stops
falling out.
5. Latch the HEPA filter door shut.
6. Vacuum any powder that fell into the work area below the Fuse Blast.
6.4.2 Cleaning the media filter mesh
The media filter mesh separates and recycles powder into the media hopper. Over the course
of regular use, clumps and hardened material can collect on the mesh and must be removed to
ensure the continued collection of recycled powder. The media filter mesh should be cleaned
after processing approximately 10 hours.
Dry powders can build static electricity charges when subjected to friction. Do not use
brooms or compressed air hoses to clean the media filter mesh. Only use antistatic
WARNING
vacuums that are grounded and bonded (e.g., NFPA 652-compliant vacuums).
To vacuum the media filter mesh:
1. Unlatch the waste hopper door to access the media filter mesh.
2. Remove the media filter mesh. Take care to not directly touch the mesh with your hand.
3. Starting from the top and moving from left to right, vacuum the media filter mesh. Note any
loose powder that falls down into the work area. Move down and across until the entire
mesh has been vacuumed and loose powder stops falling out.
Do not apply pressure or touch the mesh with your hand, vacuum, or any stiff tool.
Any force may break the mesh and prevent the component from properly filtering out

unusable powder.
4. Firmly reseat the media filter mesh back into the Fuse Blast.
5. After reinstalling the media filter mesh, close the waste hopper door. Secure the door with
its latch.
6. Vacuum any loose powder that falls into your workspace from cleaning the mesh.
6.4.3 Replacing the blasting media
During regular use, the blasting media loses effectiveness and must be replaced. Deteriorated
blasting media will fall through the media filter mesh into the waste hopper instead of returning
to the media hopper. Formlabs recommends topping up the blasting media as needed.
To replace the blasting media:
1. Ensure that the media hopper valve is firmly closed.
2. On the touchscreen, tap the Fan button. Wait a few seconds for the fan to start.
3. Open the blasting chamber door.
4. Carefully pour new blasting media directly onto the work area. The blasting media will fall
through the grate.
5. Wait 15 minutes while the fan is blowing for the media to fill the hopper. Do not overfill.
