Inside and outside the equipment should be cleaned regularly with an explosion-protected vacuum
cleaner to avoid dust accumulation. Do not sweep the dust or try to remove it with a compressed-air
An explosion-protected vacuum cleaner certified for collection of combustible metal dust is
required for cleaning. Take measures to mitigate powder spillage and avoid potential ignition
sources such as ESD (ElectroStatic Discharges), flames, and sparks. Do not smoke nearby.
An explosion-protected vacuum cleaner compliant with the following normative specifications:
Europe/International Electrotechnical Commission (IEC): Zone 22 or better, temperature Class
200°C (392°F) maximum.
United States/National Electrical Code (NEC): Class II, division 2 or better, temperature Class
200°C (392°F) maximum.
Suitable for conductive material.
Refer to the material safety data sheet (MSDS) and meet local regulations.
Recommended equipment fitted with wet filter (vacuum with submerged flow inches inert liquid)
or High Efficiency Particulate Air (HEPA) filter grade.
The equipment and accessories must be properly grounded at mains outlets only; do not
manipulate internal bonding. If static discharges or electrical sparks are noticed, stop operation,
disconnect the equipment, and contact your support representative.
The auxiliary equipment (i.e. the oven for the rebaking process) must be explosion-protected for
combustible dust and flammable vapors, according to the explosion protection document (EPD)
or explosion hazard analysis covering the probability of an explosive atmosphere and presence
of effective ignition sources as per local laws requirements. Refer to the safety data sheet of the
material being processed.
The material collector has to be electrically conductive or dissipative, and the material cannot
generate mechanical sparks. In addition, the earthing clamps are necessary to ground the material
collector during use.
Follow the cooling time and ensure a maximum powder temperature of 70°C (158°F) prior to putting it
inside the load station.
Ground the portable tank and drums using static earthing clamps during refilling or unloading.
HP recommends the use of HP equipment for unpacking 3D parts and refilling the build unit. If other
methods are used, read the following notes:
Dust clouds generated during handling and/or storage can form explosive mixtures with air.
Dust explosion characteristics vary with the particle size, particle shape, moisture content,
contaminants, and other variables.
Check that all equipment is properly grounded and installed to satisfy electrical classification
requirements. As with any dry powder, pouring this powder or allowing it to fall freely or be
conveyed through chutes or pipes can accumulate and generate electrostatic discharges,
potentially causing ignition of the powder itself, or of any flammable materials which may come
into contact with the powder or its container.
Powder, agents and solvents storage, handling, and disposal as per local laws. See the Safety Data
Sheets of your processed powder and solvent powder for adequate handling and storage. Follow
your Environmental, Health, and Safety processes and procedures.
