1⁄35Pouring Resin - Without Air Bubbles
Resin's Curse - The Air Bubble
When you start casting resin, your initial excitement about the newly discovered modeling technique may be torpedoed by a seemingly
unavoidable problem : air bubbles !
When you cast the liquid resin, small airbubbles form inside the mold. Like the bubbles in a glass of champagne, they try to
float to the top of the liquid. But when resin gets hard, these trapped air bubbles become tiny holes, like the holes in cheese.
Professional resin companies avoid this by placing the freshly casted resin in a vacuum device. The vacuum sucks out the bubbles.
Once the resin is hard, air is allowed back in, and there's not a single bubble left.
Since you and I don't have the space, the technology, the money and the experience to mess around with vacuum machines,
we need to try other ways.
There IS a way to cast resin under room conditions. It takes a bit of fidgetting, but you soon get the hang of it and
the results are crisp and bubble-free. I'll try to explain step-by-step.
Since Matrix posted a mail about problems with air bubbles when casting a 1/35 helmet, I take the helmet as an example.
