[QUOTE="Marcusthegladiator CDT, post: 99188, member: 7071"] The material is warmed and then flowed into the matrix. Then I submerge everything in ice cold water to harden the material as much as possible. It is not cured, just hard, but fragile. So I have to be carefull when removing the matrix. My matrix actualy has a slice going through it that is glued back together, so I can remove it easier. I just open the slice and peel back the matrix. Radica runs about thirty five dollars a tube, and this bridge used up one tube all together.I could use some clear matrix material, but I dont like it. Or at least the stuff we have in the lab I dont like. After removing the matrix I cure it for a few seconds, just enough to harden the outside a bit, then carfully remove it from the model. Then plung it back and forth onto the model and cure it for seconds at a time, always checking to see if its stuck to the model or not. Once im sure it wont stick to the model, I cure it for the full duration, on the model. I find if i cure off the model, things warp a tiny bit... [/QUOTE]
