FLOOR BEARING CAPACITY
The printer is the heaviest piece of equipment on the system, weighing 1134 kg (2500 lbs) . Additional equipment, such as
one or more Material Delivery Modules (MDM), will add significant weight as well. Refer to the illustration,
"Distributed
Floor Load - ProX 800 and system components" on page 6
and the table,
"Weight and Dimensions - System Components"
on page 10
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 800 single MDM are:
•
200-240 VAC, 50/60 Hz, 30A, single-phase
The facility's power circuit must have a 30A-50A branch protective circuit breaker or fused disconnect with lockout/tagout
capabilities. 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 prints 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 800 dissipates as much as 2000W of heat while printing and as much as 1200W while idle .
CONNECTION TO AC POWER
The ProX 800 is designed to be connected to primary AC power directly from the facility's power circuit to the machine's main
power disconnect. This task must be performed by a qualified electrician.
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 1 .8 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 800 print chamber and lab will depend to a certain degree on the material selection used for
printing . Regardless, the humidity should always be non-condensing and should not vary outside the range of 20-50% . Review
your material information (MSDS/SDS, product datasheet, and product labeling) for specific information on recommended
humidity levels .
