How to create bubble-free resin pieces?
Creating perfect bubble-free resin pieces requires paying attention to several key points. Here are the most important ones:
Proper mixing: Ensure that you mix the resin and hardener thoroughly and in the correct proportions. Any unmixed or over-mixed resin will result in bubbles in the final piece.
Degasification: Remove any air bubbles from the resin mixture by degasifying it. This can be done by stirring, using a vacuum chamber, or blowing into the mixture with a straw.
Surface preparation: The surface on which you will pour the resin should be clean and free of any dust, oil, or other contaminants that can trap air bubbles.
Pour technique: Pour the resin mixture slowly and smoothly to minimize the introduction of air bubbles. You can also use a resin spreader to help control the flow of resin and prevent air pockets from forming.
Temperature control: Resin curing can be affected by temperature and humidity, so it’s important to work in a temperature-controlled environment. Avoid pouring resin in hot or humid conditions, as this can cause bubbles to form.
Curing time: Allow the resin enough time to cure fully before handling or adding any additional layers. Resin takes longer to cure when poured in thicker layers, so be patient and avoid disturbing it during this time.
By following these key points, you can significantly reduce the likelihood of air bubbles forming in your resin pieces, ensuring a perfect and bubble-free final result.
