How can I remove bubbles from the uncured material?

What can I do about bubbles in the cured material? Shenzhen Little Sparrow Epoxy Resin

If the material has not yet hardened, adding heat is beneficial as it will cause the bubbles to rise to the surface. You can therefore use a hair dryer or heat torch, for example, and apply heat to your epoxy resin project at a slight distance. If the resin has already cured, the bubbles can no longer be removed.
