[QUOTE="sidesh0wb0b, post: 170582, member: 7594"] believe it or not doug, I think the material we burn out has an effect on reaction layer as well. my hand waxed crowns come out with more reaction layer than the printed ones....strange, I never thought it would make a difference. my hand waxes are usually dipped with Vacalon wax and contoured with Yeti Thowax. my printed crowns are 3DSystems FTX Cast material and theres no reaction layer to "grind" away. a few min in the invex, and the second sand blasting leaves them smooth as a baby's backside.
