Can you over cure UV resin?
So, in short yes: Resin parts can be over cured if exposed to UV light for too long. The light coming from a UV curing chamber is much stronger than the effect that sunlight has on the resin prints, and leaving them overnight will already show some signs of degradation.
Does UV resin cure on its own?
The resin can be used for a very long time, as it does not cure without the aid of a UV lamp. Curing by UV light is completed within a very short time.
How long does it take for UV to cure resin?
How Long Does It Take For UV To Cure Resin? UV curing stations and lamps will cure each resin layer in 15 to 20 minutes. Sunlight cures resin more slowly and may take about 2-3 hours to fully cure your resin print. Engineering resins reach their optimum properties after about 1 hour of curing in a UV curing station.
Why is my UV resin not shiny?
Foggy resin projects can happen for a few reasons: Make sure the mold is clean and completely dry before pouring. The mold can play a part in the finish. If the surface of your mold is shiny, the resin will be shiny. This silicone mold is very matte, therefore the resin turned out dull and matte.
What wattage is needed to cure UV resin?

How long should I cure a resin print?

Do you need to wash and cure resin prints?
Best answer: Yes! Properly washing and curing resin 3D prints is crucial, and the Anycubic Wash and Cure V2 is an inexpensive way to handle the messy reality of resin 3D printing.
Why does my UV resin have so many bubbles?
Tip 3: let the resin sit for a few minutes and check for any additional bubbles that might pop up. Resin by nature is self-leveling so there’s a possibility that more bubbles will form. Tip 4: watch those embeds! Any objects that you add to the resin may create air-bubbles.
Which is better UV resin or epoxy resin?
The durability of UV resin is limited to half a year. Furthermore, it is neither heat- nor scratch-resistant. Epoxy resin is the best option for a durable, long-lasting result that is also aesthetically pleasing for a long period of time.
