Hi Guys,
Can someone please tell me how much the shrinkage % is from blue resin print in the casting process for jewellery…
Anyone working with jewellery and cast who can tell me, i heard it’s 3%, sounds like a bit much?
Kind regards,
Martine

Hi, Martine. Some shrinkage occurs in blue resin parts during the required post-curing step. The Preform software already scales up the size of the part to compensate for this.
There is no shrinkage in casting due to any resins or models. the only way a casting could shrink would be from the investment, which ive never seen. its a big myth in the jewelry business
Sorry , Dont belive it is a myth… Just hand made a wax to fit a stone. Had to burr out the silver casting because it is slightly smaller… There is some casting shrinkage wjhen metal cools. I also make my models 2.5% larger in preform to get the finger and stone sizes to come out correct

Thanks Art, I haven’t tried the blue stuff yet, good to know. Yes my wax castings shrink too.
