ELECTRICAL REQUIREMENTS
The electrical cable ships with the printer, and consists of 1 phase + neutre + PE (section cable 2.5mm²). The phases and
protective cables must all be connected to the facility’s power.
The ProX
®
DMP100 is designed to be connected to primary AC power directly from the facility’s power circuit to the machine’s
input power. This task must be performed by a qualified electrician. The facility’s power circuit must have a 16A branch
protective circuit breaker (type D curve) with lockout/tagout capabilities.
All equipment and storage container must be grounded to prevent accumulation of static electricity.

GAS REQUIREMENTS
A customer supplied gas system (Nitrogen required when using non-reactive powders, Argon required when using reactive
powders) must be in place
before
the ProX
®
DMP100 is installed.
When installing the gas supply line:
•
Route gas supply line through the ceiling.
•
Locate the drop over the main cabinet.
The connection of the gas supply is located on the bottom right of the printer.
Gas
ProX
®
DMP100
Connection Type
Quick coupler plug, internal diameter 6mm
Flow Rate
Manufacturing : 5 - 10 L/min (0.17 - 0.35 cubic feet per minute)
Purge : 30 L/min (1.06 cubic feet per minute)
Supply Pressure
Minimum 5.5 bar (80 psi) - Maximum 6.9 bar (100 psi)
Quality
Nitrogen : 99.99% or better
Argon : 4.8 or better
For a gas supply, you may use a bulk (liquid) gas tank or gas cylinders.
If a liquid gas supply is used, the supply tubing from the gas source to the machine must be at least 20 meters (65.6 feet) long.
This distance will act as a buffer and will make certain the temperature of the gas is not below freezing point when it enters the
ProX
®
DMP100.
Caution: Allowing gas that is below 0 degrees C (32 F) to enter the ProX® DMP100 will damage the machine .
If using gas cylinders, the following is recommended:
•
Use one pack of twelve cylinders connected with an auto-switching manifold.
•
A high volume flow pressure reducer must be used for the cylinders. This allows the chamber to fill quicker.
•
Use two particle filters immediately after the reducer. One 5μm filter and one 0.01μm filter.
