No silicone molds? No Problem! UV resin DIY- Tutorial

How to make hollow pieces with UV resin without silicone molds
Como fazer peças ocas com resina UV sem moldes de silicone.

Tips for this project: The UV resin when in contact with the UV light from the torch, hardens very fast. Between layers there's no need to fully cure the resin. I only fully cure the resin when I apply the last layer.
Why do I fill the balloon with water? To prevent it from shrinking when curing the resin.

Dicas para este projeto: A resina UV quando em contato com a luz UV da tocha, endurece rapidamente. Entre as camadas não há necessidade de curar completamente a resina. Eu apenas curo completamente a resina quando aplico a última camada.
Porque encho o balão com água? Para evitar que este encolha ao curar a resina.
