Environmental Safety

The following are environmental issues concerning the Figure 4 Modular:


To allow optimum systems operation and optimum part quality, the temperature of the Figure 4 Modular system’s location should remain stable. The working range is 18-28°C (64-82°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 Printer room should have a minimum cooling capacity of 1.4 kW. We recommend an HVAC system that changes the air six times per hour. To avoid adversely affecting part quality, do not expose the Figure 4 Modular system to direct air flow from the air conditioning system.

*For Figure 4 FLEX BLK 10 material, printing temperatures outside the range of 10-30°C (50-86°F) can cause printed-part properties to change.

There are no special requirements for controlling waste heat on the Figure 4 Modular.

Humidity and Altitude

The optimal humidity in the Figure 4 Modular build chamber and lab will depend to a certain degree on the material selection. Regardless, the humidity should always be non-condensing and should not vary outside the range of 20% to 80% RH*. Review your material information (SDS, Instructions for Use, and product labeling) for specific information on recommended humidity levels.

*For Figure 4 FLEX BLK 10 material, humidity outside the range of 10-65% RH can cause printed-part properties to change.

The Figure 4 Modular system is capable of operating correctly up to an altitude of 2,400 m (7,874 ft) above mean sea level.

Sound Pressure

Overall sound pressure level for this equipment will not exceed 85 dBA, and, therefore, does not require ear protection to operate.

Disposal of Figure 4 Material and Waste

When you dispose of materials, refer to the SDS for that material and follow any applicable government regulations. All waste products (material-soaked paper towels, cleaning liquids, etc.) must be disposed of in accordance with all applicable government regulations.

Do not clean anything with uncured material on it in a sink or tub that drains into normal wastewater.

Intended Pollution Degree

Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment. The intended pollution degree for Figure 4 Modular is PD2. This means that normally only nonconductive pollution occurs. Temporary conductivity caused by condensation is to be expected.


WEEE Warning (Europe only)
