FLOOR BEARING CAPACITY
The heaviest piece of equipment 1724 kg (3800 lb) for the ProX 950. Additional equipment, such as one
or more Material Delivery Modules (MDM), will add significant weight as well. Refer to Figures 9 and 13 to
determine the total weight of the equipment to be housed in your room to ensure that you don’t exceed the
maximum load bearing capacity that your flooring can support.
ELECTRICAL REQUIREMENTS
Electrical voltage requirements for the ProX 950 single MDM are:
•
220-240 VAC, 50/60 Hz, 50A, single-phase
Power for the ProX 950 must be on a dedicated, surge protected circuit. UPS usage is strongly recommended in
areas where power fluctuations are frequent, as surges and spikes can cause damage to electronic components,
and loss of power can result in failed builds or potential damage to the SLA system.
Surge and spike suppression should carry a rating of at least 1000 joules with a clamping voltage of approximately
300 VAC. Uninterruptible power, recommended especially in areas where circuits may be affected by lightning
strikes, should be rated for 5kVA at a minimum. Make certain that no heavy equipment, especially large electric
motors (greater than 1.5 kW or 2 hp) are connected to the same circuit. Use a pass through UPS with power
conditioning. For specific information on a suitable UPS, contact a UPS manufacturer and provide the voltage
rating, current draw, and desired backup time. The manufacturer can recommend an appropriate model.
HEAT DISSIPATION
The ProX 950 dissipates as much as 4580W of heat while printing and as much as 2600W while idle.
CONNECTION TO AC POWER
The ProX 950 is designed to be connected to primary AC power directly from the facility’s power circuit to the
machine’s input power line filter. This task must be performed by a qualified electrician. The machine is shipped with
a 6 gauge, 3 wire, power cord (13 feet long) with no connector.
TEMPERATURE
The temperature in the room or location where the SLA system resides should remain stable to allow optimal
system operation and optimal part quality.
The working range is: 20°-26°C (68°-79°F)
Any temperature fluctuations greater than 3°C (5°F) may adversely affect parts built on the system. The rate
of temperature change should not exceed 1°C (1.8°F) per hour. The air conditioning system should maintain a
temperature change of less than 1°C per hour. The stereolithography room should have a minimum cooling
capacity of 3.6 kW. The air should change two to five times per hour. Avoid exposure of the SLA system to direct air
flow from the local air conditioning system to avoid the possibility of adversely affecting part quality.
HUMIDITY
The optimal humidity in the ProX 950 build chamber and lab will depend to a certain degree on the SLA material
selection. Regardless, the humidity should always be non-condensing and should not vary outside the range of
20-50%. Review your SLA material information (MSDS/SDS, product datasheet, and product labeling) for specific
information on recommended humidity levels.
