- Instructions to use the Crestaform® Rapid 8K resin
- Always shake or mix the resin thoroughly before use. This is especially true for Crestaform Rapid 8K as pigment heterogeneity will affect print quality
- Open the container and pour the appropriate amount of resin into the tank according to the size of the printer model
- Make sure to not spill the resin onto the printer, LCD screen or anywhere outside of the resin tank
- If not used for a long time, please filter the resin and pour the resin into the storage container

Printer Type LCD, DLP Printer Wavelength (nm) 405 Layer Height (μm) 25 - 50 Printing Temperature (°C) 18 - 30 Base Layer Exposure Time (sec) 20 - 40 Normal Layer Exposure Time (sec) 2.0 - 3.0 * For DLP printers, it is recommended that light power is reduced to around 2.5mW/cm2
* It is recommended that 3D resin exposure finder test prints are undertaken to find optimum cure settings- Note
- Mechanical Testing Specimen Print Orientation - 50°
- * 16 mins at 60°C + 405nm UV Post Cure for cured properties

Technical Details & Test Data
- Recommended Cleaning
- Soak the print in a clean isopropanol (IPA) (or similar solvent) bath for a minimum of 5 minutes. Alternatively, rinse the part with IPA until all the visible uncured resin has been removed. Reusing IPA in multiple cleans can reduce the cleanliness and clarity of a print
- Leave the print to dry off any residual solvent prior to post-curing
- Recommended Post-Curing
- Post-cure as soon as possible after completion of printing
- Post-cure every print for a minimum of 2 minutes under a dedicated curing UV light operating at 405nm wavelength. Alternatively, leave the print to cure for a minimum of 2 hours under direct sunlight
- Temperature-assisted UV curing will increase the rigidity of the print. It can also be used to initiate shrinkage to improve the quality of negative features. Temperature-assisted UV curing will increase the rigidity of the print

Storage & Handling
- Handling Information
Do
- Always wear Personal Protection Equipment (PPE), protective eyewear and chemical nitrile gloves when handling resin
- Shake the resin well every time before you use it or decant from the container
- If spilled, please clean the spill immediately with paper towel, and Isopropanol (IPA)
- Store it in its original container at room temperature, away from children, untrained personnel, direct or indirect sunlight, heat sources, sparks and open flames
- Use it in well ventilated rooms
- Use every sensible preventive precaution to avoid skin contact, spillage of resin, eye contact or swallowing. Make note of Local Poison Centres availability
Do not
- Expose resin to direct or indirect sunlight, UV light, heat sources, sparks and open flame while handling and storing the resin
- Touch the resin with bare hands. Always wear appropriate gloves. If skin contact occurs, wash it with soapy water. If you feel unwell, please consult immediately medical assistance
- Swallow the resin or printed objects
- Expose to children or pets
- Handle before completing training
- Expose persons sensitive to the resin components – please see Material Safety Datasheet
- Inhale the resin fumes. Use only in well ventilated rooms or areas
- Pour the resin or used IPA into the draining system
- Storage Conditions
Crestaform® Rapid 8K should be stored in the dark, in suitable, closed containers. It is recommended that the storage temperature should be between 15°C and 35°C. Ideally, containers should be opened only immediately prior to use. Keep out direct light/sunlight.
