Environmental Conditions
Temperature
To allow optimum systems operation and optimum part quality, the temperature of the Viper Pro
SLA System’s room or other location should remain stable. The working range is 23°C +/- 3
°
C
(73
°
F +/- 5
°
F). Any temperature fluctuation greater than 3
°
C may adversely affect parts built on
the system.
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 1.4 kW. We recommend an
HVAC system that changes the air two to five times per hour. To avoid adversely affecting part
quality, do not expose the Viper Pro SLA system to direct air flow from the air conditioning
system.
Beyond the temperature range that is optimum for part quality, the system is capable of operating
safely without creating a hazard between 5
°
C and 40
°
C.
Humidity and Altitude
The optimum humidity in the Viper Pro SLA system build chamber depends partly on the SL
material selection, although humidity should always be non-condensing and should not vary
outside the range of 20-50% for optimum part quality with most resins. The system can operate at
higher non-condensing humidity levels but may adversely affect part quality. Review your Viper
Pro SLA system material information, MSDS/SDS, product datasheet, and product labeling, for
specific information on recommended humidity levels. The Viper Pro SLA system can operate
correctly up to an altitude of 1000m above mean sea level.
