Formlabs Fuse Blast - Cleaning Printed Parts

3. Open the blasting chamber door.
4. Carefully pour blasting media directly onto
the work area and allow it to fall through
the grate. Monitor the media level when
pouring and ensure it does not block the
air inlet. The air inlet is located below
the work area grate, on the left side of
the machine.
5.
Wait 15 minutes while the fan is blowing
for the media to move through the system
into the hopper. Do not overfill the hopper.
If the media level is above the fill line, put a
suitable container under the media hopper
valve, open the valve to remove excess
media, and close the valve when the media
level is below the fill line.
6.
Check the media hopper window to ensure
the blasting media is diverted to the correct hopper. If the blasting media was diverted into
the waste hopper, check the media filter mesh for damage.
5.3 Cleaning printed parts
Fuse 1 generation printers surround each printed part with Surface Armor, a semi-sintered shell
that minimizes potential thermal inconsistencies which can adversely aect your parts. Media
blasting is necessary to remove Surface Armor from parts printed with Nylon 12 GF. Formlabs
recommends media blasting your parts for the best possible finish.
The Fuse Blast exposes parts to blasting media from all directions. The ionizing air rinse
prevents loose dust and media from re-settling on the parts.
The Fuse Blast extends the life of blasting media with passive media recycling. Waste powder
and degraded media naturally filter out into the waste hopper over time.
5.3.1 Post-processing with the Fuse Sift and Fuse Blast
Thanks to Fuse Blast’s passive media recycling, media life is dramatically extended relative to
standard blasting cabinets. Waste powder and degraded media will naturally filter out of the
usable media over time, giving you significantly longer life before saturation.
5.3.2 Operating the blast arm and blast gun
Use the blast gun to remove extraneous powder and Surface Armor from parts. TheFuse
Blast’s compressed air supply pulls blasting media into the air line and propels it through the
blast nozzle.
The blast arm supports the blast gun and swivels between two positions. The blast arm features
a wire guide to change its orientation between the active cleaning position and the idle
position. When idle, the blast arm is positioned vertically on the right side of the blasting
chamber. In its active position, the blast arm is in front of the tumbler basket.
