Sample was tested by ASTM E831-19 in a TMA. Ramp rate was 5 °C/min with a Ultra-High Purity Nitrogen purge of 50 cc/min.

UV Aging

Outdoor Aging ASTM D4329

Tested in accelerated outdoor weathering conditions according to ASTM D4329 (Cycle A). Test samples were exposed to defined conditions of heat, water condensation and UV light. Exposed samples were conditioned for 24 hours at 22 °C before mechanical testing. Control samples were stored at a constant 22 °C. Mechanical testing was conducted according to ASTM D638 at standard lab conditions (22 °C). “0 hrs” represents non-aged samples stored at 22 °C and tested 24 hours after post-processing.

Please note, accelerated weathering testing cannot fully represent all aging conditions. Formlabs recommends conducting additional testing relevant for your specific application needs.

Chemical Compatibility ASTM D543

Tested for chemical compatibility according to ASTM D543. The influence of various chemicals was tested by measuring tensile modulus and strength after different exposure times. Exposed samples were stored in containers and fully immersed in the test chemicals for 1 day and 1 week. After removal, exposed samples were washed and conditioned for 24 hours at 22°C before mechanical testing. Mechanical testing was conducted according to ASTM D638 using Type 4 tensile samples at standard lab conditions (22°C). Results are reported as a % difference from the measured values of non-exposed samples.
