ABS-Like Fast Resin User Guide
Shake the bottle and mix the resin in the vat before start printing!
Fast is an affordable fast curing and non-brittle general application resin ideal for model making like tabletop minis, and figurines.
It is not a tough or engineering resin but can be mixed with Blu/Tenacious for more impact resistance.
The shelf life of the resin is 2 years.
Even if it can be stored for such a long time, we still recommend that you use it in half a year.
UV Resin is a liquid sensitive to temperature, light, and time. Long-term storage will cause the components and pigment of the resin to precipitate and separate.
2. Please Note Before Printing
While the ideal printing condition for Fast is over 20C, we have printed as low as 15C as long as the bottom layers use more exposure time.
Fast is designed for MSLA printer in mind. It can work in DLP and laser SLA printers but you would need FEP film-based vat.

4. Recommend best support settings
- We recommend medium preset support setting in Chitubox for smaller prints. Heavy support for large prints on large printers.
- If you don't use Chitubox, at least download a copy and see the detailed settings for each preset and copy them over to your software of choice.
5. Cleaning
- Use a painter brush (or any brush made with hair) remove excess resins on the printed part with Use 95% concentrated Ethanol (preferred) or IPA to clean. Some form of methnol should work but make sure it does not contain acetone.
- After 4 minutes of cleaning action, remove alcohol with a hair dryer or air blower. For complex part with lots cavities, it may be a good idea to clean/dry multiple times.
- Users can check by touching the dryed surface of the part to see if it is still sticky. If the dryed surface is still sticky, wash some more and dry again.
6. Post Curing
- Fast reaches its optimal strength when the printed part is post-cured with UV after cleaning. Use 395-405nm UV light and cure for about 1-2 minutes.
- Make sure the resin is completely cleaned off and there is no alcohol left (it needs to be dry) on the print before curing.
- It is important to dry the print made by Fast completely before post-curing. There is no need to use submerge in water technique with Fast.
