Recovering powder and filling powder cartridges
Use appropriate personal protective equipment when handling loose or
unsintered powder. Wear non-reactive nitrile gloves and safety glasses. Wear a
respirator (N95 or better) if the occupational threshold limit value for airborne
particle concentration has been exceeded, if you are sensitive to dust or pollen,
or you are concerned about your respiratory health. Refer to section 3.2 Personal
protective equipment (PPE) for additional information. Handle loose or unsintered
powder only with adequate ventilation. Avoid breathing mist/vapor/spray/dust.
Do not eat, drink, smoke, or use personal products when handling powder. Avoid
contact with skin, eyes and clothing.
5.1
Operational environment
The operating temperature for the Fuse Sift is 18–26 °C (64–80 °F), with low ambient humidity.
For optimal post-processing, and particularly for recovering powder, do not exceed these limits.
5.2
Cooling a print
For detailed guidance and visual assistance, visit

.
After printing, parts need to cool in the Fuse 1’s print enclosure before being moved into the
Fuse Sift to alleviate thermal stresses so your final geometry can be achieved. The Fuse 1
automatically starts cooling parts after printing completes, and indicates the recommended
time a print should remain inside the print enclosure. This is indicated by an on-screen
notification, as well as the status card in the top-right of the
Home
screen.
The Fuse 1’s print enclosure is designed to operate at up to 200 ºC (392 °F), and
incorporates high-intensity heaters. Do not open the print enclosure or any other
access doors on the Fuse 1 during or immediately after a print. Do not handle parts
from a build chamber without allowing the entire print enclosure to cool for several
hours, or until the print bed temperature has reached ≤ 100 ºC (212 °F). Use the
provided thermal-insulating silicone gloves when handling a hot build chamber.
Failure to follow these procedures will result in serious injuries, including burning and/
or scalding of skin.
A full build chamber or a build chamber with many printed parts will be heavy. Use
appropriate precautions and correct lifting form when moving the build chamber.
5.2.1
Cooling the build chamber in the Fuse 1
After a print has completed, a message on the touchscreen displays the recommended cooling
time required for each print. All prints are subject to a subsequent cooling phase that allows
parts to steadily cool down to 100 ºC (212 ºF). Removing a build chamber from the printer before
parts have completed their initial cooling may result in warpage and deformation.
