Resin preparation:
- Shake the bottle of INFINAM® RG 3101 L for ca. 30 sec until the material is homogenous before filling into the printer
- The resin needs to be bubble free prior to printing: allow the resin to rest before printing in order to allow air bubbles to dissipate (prior degassing of the resin can help to expedite this process)
Print settings:
- INFINAM® RG 3101 L is designed to print optimally on digital light processing (DLP) and LCD machines at 385 or 405 nm (see table below for exposure time)
- At 405 nm: Critical exposure energy Ec = 10 mJ/cm² - Depth of penetration Dp = 180 μm
- It is advisable to use standard separation speed (e.g. peeling and separation speed of 2 - 4 mm/s)

- INFINAM® RG 3101 L is designed to be printed with support contact size of 0.3 - 0.5 mm for easy support removal from printed parts
- For complex geometries, lattice support structure is recommended to ensure high print success rate Washing procedure
- Wash printed parts with isopropanol (IPA) to remove uncured resin and use compressed air to accelerate the removal of residual solvent from the surface of the parts
- Recommended wash cycles: rinse 2 - 3 times (each rinse for 1 - 2 min) until excess resin has been completely removed
- Let the parts dry for at least 30 min before the next post-processing step
- Contact with washing fluids like IPA should be minimized, as prolonged immersion or sonication of the uncured parts may result in loss in the mechanical properties: do not exceed more than 10 min total exposure to IPA
- When support structures are used, they should typically be removed before post-curing
Post-curing procedures:
- After washing, the parts should be post-cured in order to achieve specified properties Below are two recommended procedures (it is recommended to flip printed parts once during UV-curing):
Method UV-curing Thermal-curing Option 1 405 nm lamp (LED, 40 W) at 80°C for 120 min 80°C for 180 min
Option 2 Broad-spectrum lamp (metal-halide, 400 W) for 30 min -

Technical Details & Test Data
- Chemical Resistance
INFINAM® RG 3101 L was tested for solvent compatibility following standard ASTM D543. Tensile specimens were immersed in various liquid media for either 24 hours or 7 days and tested following ASTM D638.

Retained tensile properties in % after 7 days immersion in test liquids:
- Long Term Environmental Stability
INFINAM® RG 3101 L was tested for its stability towards indoor and outdoor weathering conditions. The method is intended to reproduce the weathering effects that occur when the material is exposed to either solar radiation through glass (indoor conditions, ASTM D4459, Q-Sun) or to sunlight and moisture as rain or dew (outdoor conditions, ASTM G154, Cycle 1, QUV).
Note: For the indoor method, it is possible to infer that accelerated weathering times of 400 and 800 hours correspond to ca. 5 and 10 years of aging in normal conditions, respectively. For the outdoor method, it is possible to infer that accelerated weathering times of 400 and 800 hours correspond to ca. 8 and 16 months of aging in normal conditions, respectively.

Storage & Handling
- Storage Condition
INFINAM® RG 3101 L resin is a light-sensitive product protected by its original packaging. Store product in a dry location with optimum storage temperature of 10 - 30 °C. Storage beyond this recommended temperature range can adversely affect both print and product properties. Exposure of the liquid formulation to daylight and especially UV light should be minimized during storage and handling to ensure consistent print quality.
