Storage and handling notes
Review Safety Data Sheet to ensure safe handling, storage, and disposal.
Shake resin containers before printing to ensure the resin is thoroughly mixed.
To avoid contamination, do not pour resin back into cartridges.
For best performance and shelf life, store resin between 10–25 °C (50–77 °F), and keep opened resin away from direct light.
Short-term freezing during shipping is generally not detrimental to shelf life. Thaw and shake the resin cartridge thoroughly before use.
High temperatures decrease shelf life. Transient high temperature conditions (e.g., during shipping) should have a minimal effect.
Extended Properties
Representative Tensile Curves
Tensile properties were determined according to ASTM D638 (Type I). Samples were prepared following the Default post-processing workflow and conditioned at 23°C and 50% RH for 48 hours prior to testing. The displayed curve represents a single sample selected to illustrate typical stress-strain behavior. See the Material Properties section for average values.
Dynamic Mechanical Analysis (DMA)
DMA was performed using a TA Q800 with dual cantilever clamps from -20°C to 170°C using a heating rate of 3°C/min. Samples were prepared following the Default post-processing workflow. The resulting curve characterizes the material’s viscoelastic response over the temperature range and indentifies the glass transition (Tg).
Chemical Compatibility ASTM D543
Chemical resistance was evaluated according to ASTM D543. Samples were prepared following the Default post-processing workflow then fully immersed in test chemicals for durations of 1 day and 1 week. Following exposure, samples were manually wiped off and conditioned at 23°C and 50% RH for 24 hours. Mechanical testing was conducted per ASTM D638 (Type IV). Results are reported as the percentage change from non-exposed control samples. 4
Light Transmission Curve
Transmission spectra were recorded from 200 nm to 1000 nm using a Varian Cary 50 Spectrophotometer. The 3 mm sample was prepared following the Default post-processing workflow.
Thermal Expansion by TMA
The Coefficient of Thermal Expansion (CTE) was measured according to ASTM E831. Samples were prepared following the Default post-processing workflow. Testing was performed via TMA with a ramp rate of 5°C/min under a High Purity Nitrogen purge (50 cc/min).
Footnotes
- Material properties may vary based on part geometry, print orientation, print settings, temperature.
- Data was obtained from parts printed on a Formlabs printer with 100 µm Clear Resin V5 settings, washed with IPA, and post-cured according to the default workflow.
- Data was obtained from parts printed on a Formlabs printer with 100 µm Clear Resin V5 settings, washed with IPA, and post-cured according to the max strength workflow.
- Data was obtained using Grey Resin V5, and is expected to fall in the same approximate range. Some results may vary. Consult Grey Resin V5 TDS for information on printing and post-processing of samples.
- Transmission refers to the amount of visible light that passes through the part
a* and b* are more commonly associated with the CIELAB color space, where they denote axes for color measurement:
a* axis: Ranges from green to red, with negative values indicating green and positive values indicating red.
b* axis: Ranges from blue to yellow, with negative values indicating blue and positive values indicating yellow."
