INFINAM® RG 2000 L is designed to print on bottom-up digital light processing (DLP) machines. When printing with a light intensity of 9 mW/cm² at 385 nm, the recommended layer exposure time for 100 μm thick layers is 2 s, with a base layer exposure time of 3 s. Working curve data for 385 nm wavelength and 9 mW/cm². Intensity: Critical exposure energy Ec = 6 - 9 mJ/cm² and Depth of penetration Dp = 300 - 400 μm.
- Recommended washing procedure
It is recommended to wash printed parts with isopropanol to remove uncured resin. When support structures are used, they should be removed before post-curing. To achieve higher clarity in complex geometry objects, it is recommended to wash the parts in tripropylene glycol methyl ether. When support structures are used, they should be removed before postcuring.
- Recommended post-curing procedure
After washing, the parts should be submitted to ultraviolet (UV) light (intensity at ca. 5 mW/cm²) for 120 min at 80°C, followed by 180 min at 80°C without UV light.

- Note
¹ - The mechanical values were obtained on specimens printed with a DLP printer at 385 nm (9 mW/cm², XY or XZ print with 2 s layer exposure time, 100 μm thick layers). Tensile bars were tested following ASTM D638, Type V, 10 mm/min using an automated extensometer. Specimens are notched using a manual notching machine.
² - The mechanical and thermal values reported in this document derived from printing various parts with one specific bottom-up DLP machine and following the above-mentioned procedures. Those values reflect an approximation of the mean value of a range of values and are intended for reference and comparison purposes only.

Storage & Handling
- Storage and Handling Information
- INFINAM® RG 2000 L resin is a light-sensitive product protected by its original packaging. Exposure of the liquid formulation to daylight or UV light should be minimized or avoided at all during storage and handling to ensure consistent print quality. Special light sources shall be used instead.
- 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.
- It is recommended to shake INFINAM® RG 2000 L resin well before use. Degassing can be carried out before any print process. It is advisable not to store the unused resin in the vat, especially for prolonged period of usage.
- If the resin is left in the vat after printing, thoroughly mix and agitate the resin in the vat prior to any print processes. Do not return used resin from the vat back into the original INFINAM® RG 2000 L container.
