Worbla’s pellet products, Deco Art and Crystal Art, can both be used as an alternative for resin casting when you are unable to cast due to space, health, or cost reasons.
Both Deco Art and Crystal Art work best in smaller applications: the pellets can be blended and pushed into a mold. Silicone molds work very well, but hard plastic molds can also be used as long as a mold release is also used to prevent the plastic from sticking.
Some examples of Worbla pellets cast into various molds:
Deco Art and Crystal Art can be used in larger molds, but it can be more difficult the more complex the mold: you may have to reheat and re-cast to get all the details in very complex molds. Simple shapes work excellently well with Deco Art, but Crystal Art may show trapped air bubbles that are unavoidable when working with large amounts of the pellets.
Molding with Worbla’s pellet plastic Deco Art and Crystal Art is possible and can achieve a range of results depending on your needs. The Worbla products are not meant as a replacement for resin casting and we will never suggest they will give you the same result! If you require perfect casting results, be it complete transparency or fine detail capture, we strongly suggest Smooth-On’s large product catalog and excellent tutorials to achieve your needs.
But if you need it fast or if you can’t use resin due to space or cost or health, Crystal Art and Deco Art might be a great alternative.
