3. Work Flow

Print setting

Tenacious Resin is a flexible resin material that is widely compatible with MSLA/LCD 3D printers. It can also print on some 405mm SLA/DLP printers if you have access to exposure controls.

To achieve optimal results with Tenacious Flexible resin, you need to use the appropriate slicer profiles for your printer model and software. You can download the slicer profiles for Chitubox and Lychee slicers here

Clean

Use a painter brush (or any brush made with hair) to remove excess resins from the printed part.

Use 95% concentrated Ethanol (preferred) or IPA to clean. Some forms of methanol should work but make sure they do not contain acetone.

After 2-3 minutes of cleaning action, remove the alcohol with a hair dryer or air blower.

For complex parts with lots of cavities, it may be a good idea to clean and dry them multiple times.

Check the dried surface of the part by touching it to see if it is still sticky. If the dried surface is still sticky, wash it again and dry it again.

Post Curing

Tenacious reaches its optimal strength when the printed part is post-cured with UV after cleaning.

Use 395-405nm UV light and cure for about 25 minutes.
Make sure the resin is completely cleaned off and there is no alcohol left on the print before curing.
Curing by submerging the object in water will significantly increase curing efficiency.
