Special Considerations for FLEX BLK 10

Figure 4 FLEX-BLK 10 printed-part mechanical properties will change when exposed to low and high temperature and/or humidity. Parts will become either softer or tougher as temperatures increase/decrease beyond typical office environments. Similarly, impact strength will drop as temperature and humidity are decreased outside of typical office environments. In use cases where stable printed-part mechanical properties are important, FLEX-BLK 10 is recommended for indoor use, at temperatures between 10-30°C (50-86°F), and 10-65% relative humidity. The best conditions are around 20°C (68°F) and 40-50% RH (non-condensing). The printed-part mechanical properties most-susceptible to change are: notch impact strength, tensile modulus and yield strength. Please refer to the charts below for detailed information on printed-part mechanical properties as a function of temperature and relative humidity.

NOTE: The printed-part mechanical properties will return to standard when parts dry completely (back into the 10-65% RH range) and are at standard room temperature. In the case of the effects of exposure to high humidity, return to standard properties could take a day or two.
