To ensure part quality and accuracy, choose a ground floor location which will minimize vibration. The ProX

DMP100 should
not be affected by normal or incidental environmental vibration; however, the area should be isolated, either via location or
some other physical or mechanical means, from any significant internal or external vibration sources such as heavy machinery,
airplanes, or trains, which could cause unacceptable shock or vibration levels.

RECOMMENDED METAL POWDER STORAGE***
To store metal powders in your facility:
•
Use closed containers. Closed containers will prevent accidental dust generation and contamination.
•
Preferable use conductive containers or containers lined with conductive material. Containers made from a conductive
materials will help dissipate electrostatic charges.
•
Store containers on a grounded conductive surface.
•
Store separately from other chemicals such as, but not limited to, oxidizers and fuels.
•
Store in a fireproof cabinet.
•
Make certain you have small containers for small quantities of powder. Do not store small quantities of powder in large
vessels.
•
In the ideal case, large quantities of powder are stored in a suitable separate building, away from the production
environment.
Storage in closed containers will prevent accidental dust generation and contamination, while a conductive material will help
dissipate electrostatic charges.
It is also recommended to store large quantities of combustible powders in fire retarding cabinets or a specifically designed
room. While this will not prevent fire itself, it will prevent powder from igniting immediately by a fire in the vicinity of the
powder storage. This will give your personnel additional time to evacuate and will provide emergency services the opportunity
to extinguish the external fire before the powder stock ignites. In the ideal case, store large quantities of powders in a suitable
separate building, away from the production environment.
You must make certain there is no automatic sprinkler system installed where aluminum, magnesium or magnesium alloys are
stored. These materials will react with water to produce hydrogen which will create an explosion hazard.
*** Some metal powders are very reactive to Oxygen, Water, or other elements. Refer to the material SDS and all
local regulation for proper handling, storage, and disposal.
